ABSTRACT

In June 1984, we collected 735 live mussels from the Illinois
River in the vicinity of the Naples Terminal Company, Naples, IL,
between river miles 62 and 67. We engraved an identification
number on both valves, determined height and length, and noted
any damage to the shells. We replaced marked mussels on the
bottom in or near 1.5-m aluminum corrals. Mussel corrals were
grouped in two experimental (barge fleeting) plots and two
control (no barges) plots. In October 1984, we resampled the
plots. In one of the fleeted plots, barges are tied to pilings,
and corrals in that plot were bowed and pushed into the
substrate. In the other fleeted plot, barges are grounded, and
the corrals had been destroyed. Corrals in the upstream control
plot had been struck by propellers of small pleasure boats, while
the downstream control corrals were unscathed. We recaptured 3
of 16 dead shells and 175 of 735 live mussels marked in June. In
general, shell damage rates and mortality rates were higher in
the fleeted plots than in the downstream control. Growth rates
for most species were greater in the unfleeted downstream control
than in the fleeted areas, and differences between plots were
significant (P < 0.055) for Amblema plicata (the three-ridge) and
Leptodea fragilis (the fragile paper shell) . However, there were
no other statistically significant differences, probably because
of the small numbers of recaptures. Therefore, the trends for
responses other than growth in two species must be considered
inconclusive until we obtain larger samples of marked mussels and
allow more time for damage, mortality, and growth to occur.

INTRODUCTION

BACKGROUND

When this project began in 1982, the major objective was to
determine the effects of barge fleeting on mussels. The need for
such a study was, and remains, urgent because of the increase in
the number of permit requests for fleeting areas. Proposed sites
are primarily along the Mississippi and Illinois rivers just north
of St. Louis, Missouri, although encroachment of river terminals
and fleeting areas on mussel beds is a general problem on other
navigable rivers. Because there are no data on effects of
fleeting on mussel beds in rivers, permit seekers and hearing
officers are free to conclude that there are no demonstrated
effects. If barge fleeting does have adverse effects on mussels,
then many mussel beds will be damaged in the future as more and
more permits are issued.

A few examples give an idea of the magnitude and extent of
the problem. New locks and a dam across the Mississippi River at
Alton, Illinois are currently under construction, and traffic
limitations caused both by the new construction and by limitations
of the old lock have created a demand for fleeting areas in the

^

vicinity. In addition, _germits are being requested for new

fleeting areas upstream^in expectation of an increase in
commercial navigation once the new locks are opened. In just one
10-mile reach of the Mississippi River (river mile 207- 217) there

were four permit requests for fleeting areas with a combined
capacity of 240 barges (UMRCC 1982) . A major commercial mussel
bed is located in this area and at least one of the permits was
opposed by the Illinois Department of Conservation and the U.S.
Fish and Wildlife Service on environmental grounds, including
possible damage to the mussel bed. Sixty-five miles upstream on a
major tributary of the Mississippi River, the Illinois River,
there are several mussel beds where Naples Terminal Company
requested permits to fleet 563 barges. A request for expansion of
a fleeting area in the east channel of the Mississippi River at
Prairie du Chien, Wisconsin, has been embroiled in controversy
because the Higgin's-eye pearly mussel (Lampsilis higginsi) , an
endangered species, occurs there (UMRCC 1983).

HISTORY OF THE PROJECT

The original grant-in-aid award was from 1 October 1982 to 3 0
September 1983 to survey one or more mussel beds in a reach of the
Illinois River between river miles 51.2 and 54.3, where the

Soyland Power Cooperative had been granted a permit to construct a

i

barge unloading facility. The final product of the project was to

include a detailed plan and cost estimate for a post-construction

survey. The post-construction survey would have demonstrated any

effects of barge fleeting on the mussel beds over five years. JWe "\

believed funding for the post-construction surveys could

T"n

obtained from Soyland Power Company, the U.S. Army Corps of
Engineers, or a consortium of fleeting companies.

When Soyland Power Cooperative decided not to build the power
plant, because of declining demand for electricity, the project
was extended and funding increased so that a new site could be
located and another reconnaissance survey completed. In spring
1983, we selected the Naples Terminal Company at Illinois River
miles 61.4-70.2 for our study site (Figure 1). In June 1983, we
qualitatively sampled mussel beds in the area with a crowfoot bar.
The crew then quantitatively sampled a bed which eventually would
be heavily fleeted and another bed downstream which would not be
fleeted. Our sampling locations were marked permanently by steel
ground anchors whose exact positions could be determined by

triangulation from two locations on shore.

s

We were not able to secure financial support beyond that

J^ provided by the National Marine Fisheries Service and the Illinois — &-

Department of Conservation, so we changed the design of the study

to obtain results after only two summers of field work instead of

the five summers originally envisioned. _$The new^approadh was a

manipulative experiment where marked mussels were placed in both

fleeted and unfleeted areas starting in spring 1984. The next

section of the report gives details of the methodology and the

following section- describes project results through fall 1984.

Results of the 1985 field work will be given in the project

completion report in 1986.

Personnel, equipment, and travel money from the fleeting
project also were used for emergency sampling on 27-30 June 1983
in pools 14 and 15 of the Mississippi River where a die-off of
mussels had been reported by commercial clammers and state
biologists. Results are reported in Appendix E of this report.

METHODS

LOCATING MUSSEL BEDS

Initially we used a brail (also called a crowfoot bar) to
locate mussel beds in the fleeting area at Naples. The brail was
1.6 m long and had 30 4-pronged hooks or crowfeet attached to it.
We fished the brail from a 6-m boat as the boat floated downstream
with the current.

On 6 July 1983, we had great difficulty using the brail to
identify mussel beds in the fleeting area. The hooks continually
snagged on steel cables used for fleeting, submerged trees and
brush, and even a discarded automobile. One day of brailing
yielded only 12 mussels. On 12 July 1983, surface-supplied diving
was used to reexamine plots within the fleeting area where a few
mussels had been taken with the brail. An area on the west bank
near river mile 65 had the greatest density of the plots
investigated and was chosen for quantitative sampling by diving.

DIVING

For diving we used an 8-m pontoon boat equipped with an air
compressor, primary and secondary storage banks, and a control
console for air-pressure regulation and two-way communication to a
diver using a US Divers' Superlite 17 diving helmet. In shallow

water we also waded and used self-contained underwater breathing
apparatus (SCUBA) .

PERMANENT SAMPLING TRANSECTS

In June 1984, five permanent transects were laid out and
sampled in the fleeting site (Figure 2) and one transect in the
control site (Figure 1) to determine whether mussel densities,
species composition, size distribution, and shell damage initially
differed between the fleeted and control sites. Permanent
transects will allow us to relocate sampling points for long-term
monitoring of the mussel beds after our short-term, manipulative
experiment is completed.

To lay out a transect, the diver screwed a 1.2-m steel ground
anchor, normally used to anchor house trailers against wind, into
the bottom. He then attached one end of a 110-m rope to the
anchor and a float to the opposite end. The float was allowed to
move downstream in the current. The pontoon boat and diver then
moved downstream to the float, and another anchor was set by the
diver. Both upstream and downstream anchors were marked with
additional floats. The diver identified individual ground anchors
by the number of notches ground into the top of each one. We
designated transects by the ground anchors that marked them.
Thus, the transect running from ground anchor 3 to ground anchor 2
was transect 3-2 (Figure 2) . Positions of the ground anchors were

accurately determined by triangulation using a Motorola MiniRanger
III so that we could relocate the anchors even after the floats
were removed (Sparks and Blodgett, 1983) .

The 1.3-cm diameter transect rope was marked at 1-m intervals
for 100 ra with pieces of smaller nylon cord. Ends of the small
cord were knotted to allow the diver to determine each specific
interval by touch. The diver placed a 1.0 x 0.5-m (0.5-m )
sampling frame along an interval of the rope and collected all
mussels within the frame. He then placed mussels from a single
frame in a collection bag which was pulled up to the surface by
personnel on the boat.

On the boat, the contents of the collection bag were
transferred to a container and the bag returned to the diver. As
the diver moved the frame and returned to sampling, the surface
crew identified mussels to species, inspected them for damage, and
measured shell height and length. Height was defined as the
maximum dorso-ventral dimension of the shell at a right angle to
the hinge including the ligament and any wing present and length
as the maximum anterio-posterior dimension of the shell.
Measurements were made to the nearest 0.001 inch (0.002 5 cm) using
a Helios dial caliper. Mussels were returned to the diver and
either placed in the substrate in their normal position or simply
dumped onto the substrate near their original location.

10

Mean densities and standard deviations were determined for
each transect line and for all transects in the fleeting area
combined.

STUDY PLOTS

Barges at the Naples Terminal Company are fleeted by one
of two methods. Some are moved in against shore and attached
by cables to cement deadmen located farther back on the shore.
At least the inside edge of the barge nearest shore is
grounded. We refer to this type of fleeting as grounding. The
second method is to tie the barges to off-shore pilings in deep
water. We identified four different study plots: two within
the fleeting area to be used as experimental plots and two
control plots outside the fleeting area. Thus mussels were
exposed to one of three possible treatments:

1) control - no fleeting,

2) experimental - fleeting where barges are tied to pilings

3) experimental - fleeting where barges are grounded.
Both fleeted plots were near river mile 65 (Figure 2) . The

first was on the west or right bank (facing downstream) where
barges are grounded. The second was on the east or left bank
where barges are secured to pilings. One control plot was
approximately 4 km below the lower end of the fleeting area and
close to the right bank near river mile 62, and the other was
upstream on the left bank near river mile 67 (Figure 1) .

11

MUSSEL CORRALS

Enclosures were constructed to facilitate recapture of marked
mussels. Aluminum was used to make the enclosures strong,

resistant to oxidation, and light enough to handle. Each was

2

square and enclosed an area of 1.5 m . They could be pushed

approximately 13 cm into the substrate to reduce the likelihood of
mussels burrowing under them and extended approximately 8 cm above
the substrate to keep mussels from climbing out.

Corrals were placed in groups of four or five. After the
diver pushed each corral into the substrate, he wired it to at
least one ground anchor. Accurate locations for each group of
corrals were determined by triangulation.

COLLECTION AND MARKING OF MUSSELS

To collect mussels, the boat was anchored approximately 10 m
upstream of the collection site. A diver entered the water and
was directed to the upstream edge of the collection area by the
crew on the surface. He then searched the substrate while moving
to his left or right and maintaining tension on the umbilical
line. This method allowed the diver to efficiently sample a 180°
arc a given distance downstream from the boat. When the surface
crew determined the diver was approximately perpendicular to the
current from the boat, they let out approximately 1 m of umbilical

12

hose and instructed him to sweep in the opposite direction. The
diver sent mussels to the surface in collection bags.

On the boat, both valves of unmarked mussels were engraved
with an identification number. To engrave shells we used a Dremel
hand-held grinding tool powered by a 110-volt AC, gasoline-
powered generator. Some dead shells were also engraved to
determine whether dead shells would be washed out of the study
area. After engraving, the mussels were identified to species,
inspected for damage, and measured. Marked mussels were returned
to corrals by the diver, with no more than 2 5 live mussels placed
in a single enclosure. Additional marked mussels were placed
outside the corrals by dumping them into the water from the
surface or by the diver scattering them along the bottom.

SPECIES STUDIED

Mussels could respond to fleeting in different ways because
of interspecific differences in physiology, morphology, and
behavior. We intended to use one relatively thick-shelled
species, Amblema plicata (the three-ridge) , and one thin-shelled
species, Leptodea fragilis (the fragile papershell) . We were
unable to collect sufficient numbers of Leptodea fragilis, so we
supplemented them with another fragile-shelled species Proptera
laevissima (the fragile heelsplitter) . We also collected and
marked other species as time permitted. A list of scientific and

13

common names of mussel species used in this research is provided
in Appendix A.

EFFECTS MEASURED
Shell Damage

We considered mussels damaged if either valve showed chips,
cracks, and scrapes we felt were unnatural. What appeared to be
gradual wearing away of a valve near the umbones, due to scour or
the normal burrowing of the animal, was called erosion and was
not considered damage. Similarly, dents in the shells of the
fragile-shelled species were not considered damage.

Damage rates were calculated as percentages by dividing the
number of damaged mussels by the total number of mussels taken.

Mussels collected in 1984 were divided into two categories
for analysis of damage: those which were collected for the first
time, and those which were recaptured. Shells of newly-captured
mussels recorded damage accumulated during their adult life span
in the area in which they were found. Shells of recaptured
mussels recorded damage accumulated between the time they were
marked and the time they were recaptured (spanning the summer of
1984 in this study) in the area in which they were placed.

According to spokesmen from Naples Terminal Company,
heaviest fleeting activity occurs between fall and spring rather
than in summer. In fall and winter, farmers harvest grain which
is shipped downriver to New Orleans. In winter and early spring,

14

fertilizer is brought upriver for distribution to farmers. The
river seldom is closed to barge traffic by ice. Hence, our
results represent effects of a seasonal minimum in fleeting
activity.

Mortality

Mortality rates were calculated as percentages by dividing
the number of recaptures that had died between samplings by the
total number of recaptures.

Dead shells were marked in order to develop a correction
factor for mortality rates. A marked mussel which dies during
the interval between recaptures may be more likely to be washed
out of the study plot or buried beneath sediment than a live
mussel which maintains itself in the substrate at the sediment-
water interface. A mortality rate based on the number of marked
shells found dead since last being captured thus underestimates
the actual mortality if dead shells are less likely to be
recaptured than live mussels.

Comparison of mortality rates between plots assumes the
probability of recovery of dead shells is the same for each plot.
However, mortality rates are more likely to be underestimated in
the fleeted plots, where prop wash displaces dead shells, than in
control plots. Light, fragile shells are more likely to be
displaced than heavy shells. Therefore, separate correction

15

factors for mortality should be developed for each species in
both fleeted and unfleeted plots.

Growth

Growth rates are reported as increase in shell length in
centimeters per month. Mussels that were already damaged when
initially found and those that died before recapture were not
used in analyses of growth.

STATISTICAL ANALYSES

Four types of statistical tests were used to determine
whether there were significant differences in shell damage,
mortality, and growth rates in mussels recaptured from fleeted and
unfleeted areas. We used Fisher's exact test (2-tail) to
determine if mortality and damage were independent of "treatment",
that is, exposure to fleeting or no exposure to fleeting. Because
of the small sample sizes, data for the two fleeted plots were
pooled for this analysis. Each individual recaptured was either
alive or dead, and the shells were classified as either damaged or
undamaged. We also analyzed damage and mortality in all four
plots using chi-square tests of independence.

For analysis of growth we employed a one-way ANOVA keeping
the four treatments separate (upstream control, downstream
control, pilings, and grounded barges). Variances were

16

tested to determine whether to use a conventional ANOVA (variances
assumed equal) or a Brown-Forsythe ANOVA (variances not assumed to
be equal) . The ANOVA indicates whether there are significant difference
between treatments without indicating which of the four treatments
differ from each other. Hence, we used Tukey ' s studentized range
test to make pairwise comparisons of each treatment to the others.

Statistical analyses were limited by small sample size. In
some cases there were insufficient degrees of freedom for the
test, or there were entire rows or columns in the contingency
tables with no values so that expected frequencies could not be
computed. We have presented statistical analyses for the four
species with the greatest number of individuals and, where
appropriate, for all species combined.

RESULTS AND DISCUSSION

MUSSEL DENSITIES IN FLEETED AND UNFLEETED AREAS

We quantitatively sampled a total of 274 0.5-m quadrats
along five transects in the fleeting site (Figure 2) . Results

for each transect are presented in Appendix B. Densities in

o
samples ranged from 0 to 44 live mussels/m . Mean densities

(with standard deviations) were calculated for each transect

(Table 1) and were extremely variable. Mean transect densities

(and standard deviations) in the fleeting area ranged from 1.2 8 ( +

2.48) to 13.24 (+ 10.06) mussels/m , with an overall mean of 7.10
(+ 8.62) .

Seventy-seven 0.5-m samples were collected along one

transect in the downstream control area (Figure 1) . Data for each

transect are listed in Appendix B and summarized in Table 1.

Densities ranged from 0 to 32 live mussels/m , and the mean

density (and standard deviation) was 11.46 (+8.56). There were

2
more live mussels/m , on average, in the unfleeted control area

than in the fleeted area. Variances were approximately equal in

the two areas*. F

EFFECTS OF BOATS ON MUSSEL CORRALS AND SUBSTRATE

We placed 24 mussel corrals in June 1984 (Table 2) . When we
returned in October 1985, and tried to locate the corrals placed
in the experimental plot where barges had been grounded, we found

pieces from less than three. Gashes in the aluminum sheet metal
and reinforcing angle indicated that the corrals had been struck
by propellers. Most of the pieces were bent and crumpled. There
were several l-2m-deep pits in the substrate which we believe were
created by prop wash. We have observed towboats working as long
as three hours to pull a grounded barge off the shore. When a
towboat operates at full throttle in one place in shallow water,
it undoubtedly scours away the bottom. Sand and mud were probably
washed away from our ground anchors and the aluminum corrals
subsequently drawn into the props, or props may have actually
struck the substrate and our corrals. Prop wash probably
scattered and buried some of our marked mussels.

We found all the corrals near the pilings. The diver said
the top edges of the corrals were bent over and had either been
covered with sediment to a depth of 2 0 cm or pushed down into the
mud. A barge evidently settled on the corrals during low water or
had been pushed over the corrals.

Corrals in the upstream control plot had been damaged,
apparently by smaller propellers. Debris and a campsite left on
the bank indicated that the area was used heavily by recreational
boaters during the summer. Corrals in the downstream control plot
were intact and slightly silted in on their upstream edge.

MUSSELS MARKED AND RECAPTURED

During June 1984, we collected, marked, and replaced a total
of 735 live and 16 dead mussels in the two experimental and two
control plots (Table 3) . Data for all mussels marked in 1984 are
presented in Appendix C.

In October 1984, we recaptured 3 of the 16 dead shells and 172
of 735 live shells we had marked in June (Table 3). Data for
recaptured mussels are presented in Appendix D. We also collected
and marked 740 live, previously unmarked shells, so that the total
number of live, marked mussels replaced in the study area in 19 84
was 1,475 (Appendix C) . Although the recapture percentage for
mussels which were alive when marked (23.8%) was higher than that
for shells which were dead when marked (18.4%), we feel the sample
of dead shells was too small to assert that once a marked mussel
dies it is less likely to be found than one which remains alive.
We are now marking more dead shells to determine correction factors
for mussel mortality.

Recapture rates for live mussels were relatively high in the
piling plot (58.3%) and the downstream control (48.4%) (Figure 3).
High recovery rates were due, in part, to intact corrals
restricting movements of mussels and facilitating sampling by the
diver. Unrecovered mussels may have escaped from enclosures by
burrowing or climbing out where siltation had occurred, been moved
by currents, or, in the case of mussels placed outside corrals,
been missed by the diver. Recovery rates where barges were

grounded and in the upstream control plot were much lower, 11.4%
and 6.6% respectively. As previously noted, corrals in both of
these areas were destroyed.

PROBLEMS WITH SMALL SAMPLE SIZES

We found no statistically significant differences (P < 0.050]
in shell damage and mortality of mussels from the four plots
(Table 4) . When data from the two fleeted plots were pooled and
compared to the downstream control, the P value for mortality in
Amblema plicata was 0.096 and for shell damage in all species
pooled was 0.074 — none of the other values were close to 0.05.
Sample sizes were small, and in fact no damaged Leptodea fragilis
were recovered. Mussels with heavy shells, such as Amblema
plicata, are scraped and pushed down in the mud when barges are
grounded on them. We believe fragile-shelled species are crushed
to pieces. Since divers did not recover small shell fragments
(even if they had the particular fragment with the number on it
might not have been recovered) , our results probably
underestimate the number of fragile-shelled species damaged or
killed. With larger sample sizes, between-plot differences in
damage and mortality of heavier-shelled species are more likely
to be significant.

Shell growth rates differed between plots for Amblema
plicata, the species with the largest sample size (Table 5) . The
P value for Leptodea fragilis, the species with the next largest

sample size, was 0.055. Although the ANOVA test detected
differences between plots, paired comparisons and multiple range
tests could not detect which of the plots differed from each
other, again, because of the low power associated with small
sample sizes.

In summary, while there was a significant difference in
growth rates between plots for Amblema plicata and while trends
are evident for other effects (mortality and damage) and other
species, results must be considered inconclusive until we obtain
larger samples of marked mussels and allow more time for growth,
damage, and mortality to occur. The additional sampling in 1985,
and any subsequent sampling, will increase the number of
recaptures and enable us to draw more definitive conclusions.

With the above cautions in mind, we next present graphs
showing trends in shell damage, mortality and growth rates of
Amblema plicata, the species with the most data, and, where
appropriate, all species pooled. In general, most of the other
species showed similar trends. Since only five marked mussels
were recaptured from the unfleeted upstream control, they were
not included in the graphs of recapture data.

SHELL DAMAGE IN MUSSELS COLLECTED FOR THE FIRST TIME

The highest damage rate (14 of 116 live mussels, 12.1%) was
in the upstream, unfleeted control plot (Figure 4). None of the
41 mussels initially collected at the upstream control in spring

1984 were damaged. All the damaged mussels (14 of 75 - 18.7%)
collected at the plot were found in fall after use of the area by
recreational boaters.

The next highest damage rate was in the grounded plot where
107 of 952 (11.2%) mussels collected in 1984 were damaged. The
spring rate was 4.5% (17 of 3 74) and the fall rate was 15.6% (90
Of 578) .

The spring damage rate for the plot where barges were
attached to pilings was 2.7% (7 of 264), the fall rate was 6.1% (2
of 33), and the total rate was 3.0% (9 of 297). We presume that
rates were relatively low in the piling plot because barges were
usually in water deep enough to keep them from contacting the
bottom and the mussels.

The lowest overall damage rate of 2.7% (3 of 110) was in the
downstream control. The spring rate there was 1.8% (1 of 46) and
the fall rate was 3.7% (2 of 54).

In every plot, the percentage of damaged mussels was greater
in the fall 1984 collection than in the spring 1984 collection,
indicating that a detectable amount of additional damage was
being done in a period as short as 3.5 months.

Data for Amblema plicata, the most abundant species, showed
a similar trend (Figure 5) . Highest damage rates were in the
upstream control (20.8%) and grounded plots (15.0%). The lowest
damage rate (1.2%) was in the downstream control plot. We
collected no unmarked Amblema plicata in the piling plot.

31

SHELL DAMAGE IN RECAPTURED MUSSELS

The same trends are apparent for new damage to marked
mussels which occurred between the times mussels were collected
and marked in spring and recaptured in fall. With all species
combined, the highest damage rates were from the fleeted plots
(20.4% in the grounded plot and 19.0% in the pilings) (Figure
6). Again the lowest damage rate (8.3%) was in the downstream
control. Only five marked shells were recaptured from the
upstream control plot. Results for Amblema plicata were
similar (Figure 7) .

MORTALITY

With all species combined, the highest mortality rate
(13.8%) was in the pilings (Figure 8). Rates in the grounded and
downstream control plots were 6.1% and 5.0% respectively.

Again, low numbers of recaptured individuals made it
difficult to draw conclusions from the mortality rates for
individual species. Data from 116 recaptured Amblema plicata
(only four marked Amblema plicata were recaptured from the
upstream control) showed higher mortality rates in the fleeted
plots than in the downstream control with the highest rate
(13.5%) from the piling plot (Figure 9). While the bottom was
more disturbed in the grounded plot, the piling plot tended to

have barges fleeted there a greater percentage of the time. When
we sampled the piling plot in October, the diver could not get
under the barge to the corrals, and the Naples Terminal Company
moved the barge for us. As previously mentioned, it appeared
that a barge had settled on top of the corrals and mussels, and
mussels may have suffocated. No fragile-shelled mussels
(Leptodea fragilis or Proptera laevissima) were recaptured at the
grounded plot.

In the downstream control plot, only three recaptured
experimental mussels, one Leptodea fragilis and two Proptera
laevissima, had died between June and October. We have noticed
these two species suffer higher mortality in handling and in
aquaria at our laboratory than Amblema plicata, so they may be more
sensitive to handling stress or water quality factors. As
previously mentioned, comparatively low mortality rates in the
fleeted plots could be an artifact of displacement of dead fragile-
shelled species.

GROWTH

Growth rates are usually greater in younger mussels of a
given species. To adequately compare growth rates of individuals
from different treatment plots, it is necessary to collect enough
individuals of different ages from each plot to construct growth
curves. At present we do not have enough data to delineate these

37

growth curves. The following interpretation of growth rates for
Amblema plicata, the most frequently recaptured species (116
recaptures) , is based on available data and does not account for
differences in mean size and age of mussels from different plots,

Growth rates for Amblema plicata were greater in the
downstream control plot than in either of the fleeted plots
(Figure 10) . Both growth and mortality rates for this species
were greater in the pilings (0.022 cm/month, 13.5%) than in the
grounded plot (0.017 cm/month, 5.0%).

SUMMARY

1. This is an interim report on a continuing study of effects of
barge fleeting on mussels in the Illinois River at Naples,
Illinois. Results will be used to evaluate requests for fleeting
permits where proposed fleeting sites and mussel beds overlap.

2. In June 1984, we collected, marked, and replaced 735 live and 16
dead mussels in two experimental (fleeted) and two control
(unfleeted) plots. In one fleeted plot barges were tied to
pilings, and in the other barges were tied to deadmen and grounded
along shore. Mussels were placed in 25 aluminum corrals up to
normal densities, and additional mussels placed around the corrals.

3. In October 1984, we recaptured 3 of 16 dead shells and 175 of
735 live mussels. We also collected and marked 740 live,
previously unmarked mussels bringing the total number of live,
marked mussels in the study area at the end of 1984 to 1475.

4 . Corrals in the area where barges were grounded were destroyed
and remaining pieces had obviously been struck by large
propellers. There were several 1-2-m deep pits in the substrate
which may have been created by prop wash. Corrals by the pilings
were bowed and pushed into the substrate but otherwise intact.
Corrals at the upstream control site had been struck by small

41

propellers, probably pleasure boats which were beached at an
adjacent campsite. Corrals at the downstream control were
untouched.

5. In general, shell damage rates and mortality rates were higher
in the fleeted plots than in the downstream control, but none of
the differences were significant (P < 0.055) with the small sample
size available. At the unfleeted upstream control plot, none of
the 41 mussels collected in June were damaged. In fall, after
summer use of the area by recreational boaters, 14 of 75 mussels
collected were damaged.

6. Growth rates for most species were greater in the unfleeted
downstream control than in the fleeted areas. Differences between
plots were significant (P < 0.055) for the most frequently
recaptured species, Amblema plicata and Leptodea fragilis, but not
for any other species.

7. Any effects of fleeting on mussels were probably at seasonally
minimal levels during our study. Fleeting activity reaches a low
during summer according to spokesmen for Naples Terminal Company.
Therefore, these trends must be considered inconclusive until we
obtain larger samples of marked mussels and allow more time for
damage, mortality, and growth to occur.

Appendix E. Report on emergency sampling to verify reports of a
mussel die-off in the Upper Mississippi River.

In September 1982, fishery biologists attending the meeting
of the Fish Technical Section of the Upper Mississippi
Conservation Committee reported seeing an unusually large number
of mussel "meats" (the soft interior tissue of the mussels)
floating in the Mississippi River in July from Rock Island,
Illinois, to as far north as Lacrosse, Wisconsin (UMRCC 1983) .

In spring 1983, commercial clammers who used diving gear
reported large numbers of freshly dead shells in formerly
productive beds. Mr. Arnold ("Bill") Fritz, commercial fishery
biologist for the Illinois Department of Conservation, asked us
to investigate and guantify the mortality in two beds in Pools 1*
and 15 near Rock Island.

We sampled a total area of 8 m in Pool 14, 100 m from the
Illinois shore (river mile 494.7) and 4 m in Pool 15, 150 m
upstream of Arsenal Island at the entrance to Sylvan Slough,
approximately 50 m from the Illinois shore (river mile 486.0).
We used 0.5-m2 steel sampling frames and the surface supply
diving gear we described previously.

Recently dead mussels met the following criteria:

1. periostracum (horny brown/black layer covering the
outside of the shell) retained,

2. valves firmly joined at the hinge,

3. interior nacre shiny, not chalky,

91

Appendix E continued.

Results from both pools verified the commercial clammers'
reports (Table El) : 35-42% of the commercially valuable Amblema
plicata (three-ridge) and Megalonaias gigantea (washboards) had
died recently. Mortality in other species for which we had
adequate sample sizes (30 or more individuals) ranged from a low
of 9.8% for Leptodea fragilis (fragile papershell) to a high of
37.6% for Quadrula pustulosa (pimpleback) . Ms. Pamela Thiel,
Wisconsin Department of Natural Resources, conducted emergency
sampling in Pool 10 and found 20-40% of the mussels had died
recently (UMRCC 1983).

We submitted samples of living but moribund individuals to
Fritz and to Richard Ruelle, Ecological Services Office, U. S.
Fish and Wildlife Service, Rock Island, Illinois. They in turn
submitted them to several laboratories for contaminant analyses.
According to both men, the lab results indicated no unusually
high concentrations of heavy metals or organic contaminants,
although background levels for freshwater mussels have not been
determined. Another possible cause for the die-off could be
biological — an outbreak of parasites or disease.

Dr. John Nickum, Iowa Cooperative Fisheries Unit, Iowa State
University, is compiling information about the 1982-1983 mussel
die-off for the Upper Mississippi River Conservation Committee,
and a copy of Table El was mailed to him on 8 March 1984.

In July 1985, another massive die-off of mussels appeared to
be in progress. Biologists were reporting meats floating in the
Mississippi River, and divers were finding shells with decayed
meats inside and live mussels which were gaping and too weak to

resist a mildly forceful attempt by hand to open their shells.
The State Fish Pathologist of the Illinois Department of
Conservation, Mr. Rod Horner, examined some of these moribund
individuals and reported that cilia on the gills were still
beating and the animals appeared to be infected with Columnaris-
type bacteria. He was unable to determine whether the bacteria
caused the morbidity or simply invaded the mussels after they
were weakened by some other primary cause.

The finest beds of mussels remaining in the Mississippi,
including some rare and endangered species, lie within the area
of the die-off s, and we believe a program to determine the cause
should be concerted as soon as possible.
