ABSTRACT
A study of the pink shrimp, Penaeus duorarum, on the Tortugas fishing
grounds was undertaken during 1957 and 1958 to provide information on
the nature of the relation between the size of shrimp and the depth of
water where they occur, together with fleet concentrations and degree
of discarding of small pink shrimp. The average carapace length of both
male and female shrimp increased both with depth of water and with
northerly distance from the Florida Keys. Snnall pink shrimp were most
abundant from September 1957 through May 1958, appearing on the
eastern and southeastern portion of the grounds, where the highest try
net catches were made. The fleet concentrated there during December
to June but was more widely distributed during the summer. Apparently,
few small pink shrimp were discarded.
INTRODUCTION
THE FISHERY
The pink shrimp, Penaeus duorarum, sup-
ports valuable commercial fisheries off
the south coast of Florida and the Cam-
peche area of the Gulf of Mexico. This
species is of recent economic importance,
having been caught in large quantities
only since 1950. Little is known of the
details of its life history and much has to
be learned before a rational conservation
plan can be devised for the fishery. The
present investigation has been one phase
of a research program on the pink shrimp
and its fishery on the Tortugas grounds
off the southern end of Florida. The work
was supported by a Saltonstall-Kennedy
funds through the U. S. Bureau of Com-
mercial Fisheries, Contracts Nos. 14-17-
008-7 and 14-17-008-23.
The Tortugas shrimping grounds (fig. l)
are roughly rectangular in shape, about
60 miles long (east and west) and 25 miles
wide (north and south). The eastern corner
of the grounds is located about 12 miles
north -northwest of Key West, and the
grounds extend past the Dry Tortugas
Islands. The depth of water on the fishing
grounds ranges in a gradual gradient from
about 9 fathoms on the east to about 25
fathoms on the west, with most fishing
taking place in depths from 11 to 19
fathoms. The bottom is mostly white sand
and mud. Some outcroppings of rock
occur, esi>ecially in shallow extension of

the Keys from Key West to the Dry
Tortugas. Although shrimp occur outside
the regularly fished area, fishing is diffi-
cult and hazardous because of the presence
of loggerhead sponges, coral, and other
obstructions. Small clear areas are to be
found in the outside regions and these are
occasionally trawled with the aid of a
lighted buoy set out by the fishermen.
The exploitation of the Tortugas shrimp
population developed rapidly, drawing
boats from older grounds in Florida and
from many other southeastern and Gulf
States. By 1951, the landings were over
19 million pounds (heads on) and approxi-
mately this quantity has been landed in
each succeeding year, except 1952, when
only 11 million pounds were landed. The
catch has thus been maintained over 9
years of the fishery. This does not suggest
that overexploitation has occurred, but
some persons in the industry are certain
that the catch has been maintained only as
a consequence of a great increase in fish-
ing effort coupled with the use of small
sizes of shrimp which were formerly
discarded. Information on the sizes dis-
carded or kept is difficult to obtain, but
there is a greater tendency for buyers to
accept small shrimp in recent years.
PURPOSES OF THE STUDY
The principal purpose of this study was
to investigate the relation between the
size of shrimp and the depth of water
where they occur. Fishermen's observa-
tions and research data suggested that
pink shrimp on the Tortugas grounds in-
crease in size as water depth increases,
but details of this relationship were lack-
ing. A second purpose was to investigate
the extent to which fishermen discard
small shrinnp. A wide range of sizes of
shrimp are caught in the trawl nets. The
smallest sizes are often thrown overboard
with the vmusable part of the catch, and
the extent to which discarding is done is of
importance to an understanding of the
fishery. A third purpose was to study the
distribution of fishing vessels on the
grounds to deternnine whether effort was
concentrated in certain areas, and whether
seasons, weather, occurrence of seaweed
and jellyfish, or other factors influence
the distribution of fishing.
The present report summarizes the
results of 13 months' field observations.
Several factors, such as weather, mar-
kets, season, and size of boats, were
expected to affect the results of this
research. As the work progressed, other
factors, unsuspected originally, were
shown to influence the size -depth rela-
tionship and the distribution of fishing
effort. In the following analysis the effect
of the important variables on the results
is described, and where possible meas-
ured. The results are then presented, and
their significance in relation to the man-
agement of the fishery is discussed. These
data cover a single year, and one that was
not altogether "typical." The tempera-
tures of southern Florida during the winter
of 1957-58 were extremely low, and this
may have had some effect on the behavior
of the shrimp.

METHODS AND MATERIALS
VESSELS AND GEAR
Data were gathered from catches made
by chartered commercial shrimp trawlers
and from observations made from airplane
flights over the grounds. The boats used,
the Captain Mack, the Danny Boy, and th.e Joanie,
are typical "Florida -type" shrinnp
trawlers. They are 63, 55, and 69 feet in
length, respectively. The Captain Mack was
used from September 1957 to mid-April
1958 (table l). She was then sold and the
Danny Boy secured and used until late
September 1958, when she was acciden-
tally rammed and capsized. The last two
cruises were made on the Joanie.
During the first six cruises positions
were determined by the radio direction
finder on the chartered vessel. A small
portable directionfinder was also acquired
for use in case of the failure of the ves-
sel's instrument. During subsequent
cruises the dead-reckoning navigation was
improved by the use of a portable pelorus
for obtaining more accurate visual fixes
on navigation aids. Positions on the
northern portion of the area were difficult
to locate accurately, owing to the geo-
graphical location of the radio stations.
After cruise 10 celestial navigation was
used to supplement the radio direction
finder since fishing is carried on at night.
Depths were determined chiefly by use
of a fathometer. During the first several
cruises depths were checked by leadline
soundings and by bathythermograph lower-
ings, and the fathonneter was repaired and
checked to correspond. Fathometer tapes
were nnarked and retained.
The gear ennployed in sampling con-
sisted of standard commercial trawls, as
described by BuUis (1951) and Knake.
et al. (1958). On cruises 1-5 and 7-15, a
90-foot "two-seam flat" trawl was used.
On cruise 6 a 90-foot balloon net was
employed to avoid loss of the regular net
on the rough bottom. On cruises 16-21,
two 45-foot "double-rig" trawls were
used; and on cruises 22 and 23, two 50-
foot double -rig trawls. In addition to the
big trawls described above, 15 -foot try
nets were used regularly. On some tows
of cruises 1-11 a large try net, measuring
about 30 feet, was used in place of the
main trawl. Descriptions of all nets used
on the various cruises are given in table 1.
The research plan provided for two
cruises each month, starting in November
1957 and ending in November 1958. (Two
prelinninary cruises were made during
September 1957 by Bureau of Commercial
Fisheries scientists.) This plan was ac-
connplished in all months except June,
October, and November 1958 (in which
one cruise was made each month) despite
the unusually bad weather experienced
during the study period. A total of 23
cruises was made. Sampling stations are
depicted in figure 2. Fishing was done at
night and tows were ordinarily limited to
1 hour instead of the usual 3 hours nnade
by fishermen.

Note: On cruises 1, 3, 6, 8 and 9 large try net of 1 3/4" mesh was used on some tows
(sde ^pendix).
When the big trawl was retrieved the
catch was dumped on deck. The large
items, including sponges and big fish,
were removed. The remaining catch,
including shrinnp and small fish, was
mixed with a shovel and a sannple taken
for study. A constant sample size would
have been desirable, for statistical analy-
sis, but was not feasible. The number of
shrimp in these samples varied from
about 40 to about 200. These shrimp were
sexed and measured to the nearest 0.1 mm.
carapace length. This measurement was
from the postorbital notch to the posterior
edge of the carapace. "Size" of shrimp
hereafter refers to this carapace length.
Appendix table 3 shows the relation be-
tween carapace length, total length, and
weight of female shrimp.
Shrimp taken in try-net hauls were
measured if more than 20 but fewer than
100 were caught. If fewer than 20 were
caught, they were not measured, but were
counted and sexed. To determine relative
abundance of shrimp, counts were made

of the numbers of shrimp caught in
standard try -net tows. These estimates
were begun with cruise 7.
OBSERVATIONS ON FLEET ACTIVITY
The fleet concentration has been ex-
pressed in terms of the number of boats
fishing in a given area. This information
was obtained by counting boats seen from
the charter vessel on each trip and from
airplane flights over the grounds. Counts
of vessels from the charter boat were
made at the time each drag commenced.
Boats within sight were counted from each
side of the vessel. This routine was car-
ried out in cruises 1 -7. After cruise 7 a
different method was employed, the boats
being counted in various sectors at any
time during the tow. The size of the angle
comprising a sector varied depending on
the number and grouping of boats visible.
The number of boats seen was plotted on
a chart. As much care as possible was
taken to avoid counting a given boat more
than once. Maximum range of visibility of
boats is estimated to have been 8 miles.
Fishing is done at night in this fishery
and the boats were located by their lights.
Out to a radius of about 3 miles the
pattern of lights is clear enough to dis-
tinguish shrimp boats from other boats;
beyond that distance the lights blend and
possibly vessels other than shrimp boats
were occasionally counted. Other than
shrimpers there is little night traffic,
and few false identifications were believed
to have been made. On any given night
only part of the shrimp grounds were
covered by the research vessel, so that
the total fleet was never observed at one
time.
The aerial observations were made on
flights out of Key West and Marathon.
Flight patterns were arranged to allow
observation of the entire grounds within
2 hours. A single-engine airplane was
used without floats, and the pilots were
understandably reluctant to fly far fronn
landing fields at night. Hence flights could
only be made when conditions were favor-
able, and only seven flights were made.
Boat lights were counted by two observers
on opposite sides of the plane using hand
counters. The flight pattern was arranged
so that overlap in counts was minimized.
Boats tied up at docks in Key West and
Marathon were also counted during the
flights. Complete counts of the boats in
the fishery each night of the flight were
obtained in this manner.
SHRIMP DISCARDS
Observations of the amount of shrimp
discarded were made from the charter
vessels, from fishermen's logbooks, and
at heading houses. Little discarding was
done by the fleet during the period of
observation since virtually all sizes caught
could be sold. However, some shrimp are
always thrown back; for example, damaged
shrimp and shrimp that have recently
molted are commonly discarded but are
usually not abundant. "No" discarding
(meaning no conscious rejection of pink
shrimp of any size except dannaged indi-
viduals) was done from the charter vessels
from about February through August.
Before and after this period some of the
snnaller sizes were thrown away. When
this occurred, unselected samples were
taken and the whole shrimp were recov-
ered, counted, and measured. In addition,
a sample of the heads of the shrinnp kept
by the crew were recovered, counted,
and measured. This permitted an estimate
of the total amount of shrinnp discarded
from the total catch. Occasionally a cor-
rection had to be made, to allow for part
of the catch which was iced down without
being headed. This occurred when the
catch was so large that time was not taken
for heading, or if the shrimp were so
small as to make heading tedious.
Two circumstances reduced the use-
fulness of data on discards from the
charter vessels, hi the first place the
captain of the Captain Mack and later of the
Danny Boy had a market for small shrimp
to be used for fish bait, a market which
was not available to most others. Per-
haps, as a consequence of this, he kept
smaller shrimp than usual. Secondly, the
hauls made by the charter boats were of
shorter duration than usual in commer-
cial practice, resulting in smaller catches,
which may have affected discarding prac-
tices. Hence the data on discards may
provide only estimated maximum and
mininnunn discard sizes.
TREATMENT OF DATA
Size Distribution of Shrimp
Female pink shrimp are larger than
the males and a sample containing both
sexes produces a bimodal size distribu-
tion. The sex ratio in the total samples
approximates 1:1, but there is consider-
able variation in the sex ratio among
shrimp taken in individual samples. Con-
sideration was therefore given to the use
of only the females in calculating mean
sizes of shrimp found on the fishing
grounds. This would, of course, describe
only half the population, but if the sizes of
both sexes have a linear relation, descrip-
tion of the distribution of one sex will
provide an approximation of the size dis-
tribution of the other sex. The average
sizes of males and females of all samples
of 30 or nnore shrimp of each sex are
plotted in figure 3. All sizes and all depths
sampled are included. The figure shows
that there is a linear relation between the
sizes of the two sexes. Hence the average
size of females was selected to illustrate
the size distribution of shrimp on the
fishing grounds. For comparison four
diagrams were constructed using male
shrimp only.
Sampling Variation from Single and
Double Nets
While this study was vinder way the
shrimp fleet, and also the chartered ves-
sel, was in the process of changing from
the use of a single trawl to a double rig.
To determine whether this had an effect
on the sampling, the variation of mean
lengths and sex ratios of shrimp among
samples was analyzed. This also pre-
sented an opportunity to check the trawl
as a sampling device.
Repeated samples were taken from a
single catch. During cruise 16, the catch
from tow 10 was sampled three times
and during cruise 17, the catch from tow 8
was sampled four times. The average
carapace length of males, of females, and
of sexes combined are recorded in table 2.
The numbers of individuals measured and
the sex ratios are shown for each sample.

The mean lengths show little variation
and indicate that the sannpling technique
provided a representative index of the
sizes in the catch.
Catches of nets from 10 tows of cruise
16 were examined to discover whether
they differed in respect to the average
size of the shrimp and to the sex ratio
(table 3). Carapace length differences of
male and female shrimp combined, from
port and starboard nets, did not exceed
1.4 mm. within individual hauls. Neither
net consistently caught the larger average
shrimp. The variation in sex ratio of
shrimp caught by the two nets was not
extreme. These results justified pooling
catches of the two nets before drawing
the samples, or drawing them from either
net.
Effect of Trawl Mesh Size
Ideally, the same trawl cod end should
have been used throughout the study;
however, trawl nets do not wear well and
such a procedure was not possible. The
nets used were bought as 2 -inch stretched -
mesh manufacturer's measure. Because
of variations resulting from the manu-
facture, preservation, use, and other fac-
tors, trawl cod ends can vary greatly in
average mesh size (Medico, 1958). This
was evidenced in the present study. Cod-
end meshes were measured at intervals
for each shrimp net (table 1 ).
Graham (1956) found that the sizes of
meshes in trawl cod ends govern the
average size of the fish caught. This has
also been shown for shrimp (Regan g< aL,
1957) and it was considered necessary
to determine how the different sizes of
shrimp trawl cod ends might affect our
results. The average size of female
shrimp caught by the main nets was
compared with the average size of female
shrimp caught by try nets fishing sinnul-
taneously (fig. 4). At the top of the figure,
sizes of shrimp in catches by a 1 3/4-
inch mesh try net used for the first half
of the study were compared with catches
of two main net cod ends, one with 1 1/4-
inch mesh and one with 1 3/4-inch mesh.
The results suggest little influence by the
nneshes of these two nets on average
female shrimp sizes.

most of the remaining time, are compared
with catches of four main net cod ends,
including the 1 3/4 -inch mesh net used in
the above analysis. The results indicate
that the try net (1 7/8-inch mesh) caught
a somewhat larger average size of shrimp
than the main nets, but that the size
selectivity of the nets did not materially
affect the average size of female shrimp
sampled.
Shrimp Size Isopleths
Several methods were considered for
the analysis and presentation of the data
describing the size distribution of shrimp
on the fishing grounds. However, the data
would not fully satisfy the requirements
or assumptions of several statistical tests
and the decision was therefore miade to
present the results graphically. Diagrams
have been constructed showing the areas
of the fishing grounds where shrimp of a
certain size range occurred. Isopleth
lines were drawn on charts of the fishing
grounds, joining interpolated points from
observed average size of female shrimp.
Standard isopleths of 2.5 mm. head -length
intervals were used, the smallest being
20.0 mm. Data from successive cruises

with similar distribution of shrimp sizes
were pooled. The diagrams were con-
structed from data presented in the appen-
dix.
SEX RATIO
The sex ratios in each sample which had
at least 30 of each sex showed no marked
difference with changes in the size of
female shrimp (fig. 5). The ranges of sex
ratios for each cruise are shown in
figure 6. The mean percentage of females
varied considerably for each cruise, sug-
gesting that either there is grouping by-
sexes on the grounds or our sampling
induced variation, or both. There was an
indication of fewer females in the catches
from September to December, while during
January there were more than 50 percent
females; there were close to 60 percent
females during July-September.

SIZE OF SHRIMP
DISTRIBUTION OF SHRIMP BY SIZE
AND DEPTH
The average size of shrimp on the fish-
ing grounds increases with depth. This
relationship is illustrated by plotting the
average sizes of all samples throughout
the year against depth, keeping the sexes
separate (figs. 7 and 8).

Figure 8.— Relationship of depth of water and average size of Figure 9. — Relationship of the annual average size of shrimp

there is a considerable range of sizes
at all depths. Some important causes of
this variation will be discussed in sub-
sequent sections.
The following figures (10 to 13) contain
data gathered on groups of cruises and
these points should be noted:
1. The average size (carapace length)
of shrimp on the grounds.
2. The distance between isopleths.
When the standard isopleths are close
together, the average size of shrimp is
changing rapidly and conversely.
3. Direction of the gradient. When
the isopleths are parallel over some dis-
tance on the grounds, a positive gradient
exists.
Examination of these isopleths shows,
with minor exceptions, that two patterns
of size distribution predominate on the
Tortugas grounds. One is the increased
size with depth and the other a size
gradient in a northerly direction irre-
spective of depth. Without complete cov-
erage of the fishing grounds during each
cruise, a complete evaluation of the sig-
nificance of these two patterns is not
feasible. We have shown in figures 7,
8, and 9 that a size -depth relation exists
but we must consider that such a rela-
tionship may be a function of diffusion
or dispersion of individuals from the
Keys. Considering the number of cruises
in which the resultant isopleth lines cross
fathom contours, we strongly entertain
this possibility.
These data suggest that small shrimp
move onto the grounds from the east
and southeast and increase in size as

they move in either a northerly or north-
westerly direction. There is no distinct
seasonal pattern in the size -depth rela-
tion. Small shrimp predonninate on the
grounds during the months of September
through May.
Using as an index of abundance the
number of shrimp caught per hour in
the standard try net, additional infor-
mation on shrimp movements was ob-
tained. Catches are charted on the fol-
lowing graphs, and the diameter of the
circles denote the number of shrimp
taken per try -net hour (figs. 14 to 16).
The greatest abundance occurred from
December 1957 to January 1958 and from
March to June 1958. Catches during these
periods were made in shallow water on
the southern and eastern sectors of the
grounds. This evidence indicates a period
of recruitment during the winter, with
shrimp entering the grounds from the
south and east, much as was shown by
the size -depth relation.
FLEET CONCENTRATIONS
Most of the data on fleet concentra-
tions were obtained from observations
made on the charter vessel. These ob-
servations were made on every cruise
and hence are more complete than those
made from airplanes. Airplane flights
over the grounds at night provide spatial
distribution and estimates of the total
number of vessels trawling. Seven air-
plane flights were made (table 4, p. 21).
The number of boats observed from
the charter vessel are totaled for 5-mile
squares and are represented by symbols
denoting the various concentrations (figs.
17-19). These figures can only be con-
sidered as rough estimates since the
diagram for each cruise usually repre-
sents a total of three nights' observations.
Boats moving from one location on the
grounds to another during the cruise
could have been nnissed altogether. Vary-
ing visibility on the fishing grounds also
produces errors.
While observations on the distribution
of fishing effort are incomplete, some
general seasonal trends in fishing effort
can be seen. During the period December
to June the largest concentrations of
vessels were observed and were located
on the eastern and southeastern portions
of the grounds. An exception to this
occurred during October when concen-
trations of over 35 vessels per 5 -mile
square were noted on the southwestern
portion of the grounds. During the re-
mainder of the year the vessels generally
covered the entire grounds, their distri-
bution being restricted by the State con-
servation area and by the occurrence of
algae.
The distribution of fleet concentrations
agrees well with the abundance indices
of pink shrimp in time and space. The
largest catches of shrimp and the largest
number of vessels were found on the
eastern and southern portions of the
grounds, and these values were also
highest during the months from December
to June.
SHRIMP DISCARDING
Since small shrimp bring a lower price
than large shrimp, fishermen sometimes
discard the small ones. This practice is
important in the analysis of the fishery
because shrimp which are caught and
then discarded are not included in catch
records. This lowers the catch per unit
of effort of a vessel and introduces an
error in the average size of shrimp
caught. Estimates of discard in this study
have come only from the research vessel
for reasons discussed earlier. Observa-
tions were made on (1) the sizes of
shrimp discarded compared to those re-
tained, (2) the ratio of times fishermen
discarded shrimp to the times that they
did not discard shrimp, and (3) the possi-
ble influence of different size distribu-
tions causing fishermen to discard.
To obtain information on the sizes of
shrimp discarded compared to those re-
tained, heads from shrimp that had been
retained and whole discarded shrimp
were measured during five cruises (fig-
ure 20). When discarding occurred, vir-
tually all shrimp as large as 19 mm.
(smaller than 100 count, heads off) were
discarded and about 80 percent of 22
mm. and about 60 percent of 25 mm.
were discarded. Practically no shrimp
larger than 28 mm. carapace length (60

count, heads off) were discarded. On
certain instances fishermen left small
numbers of large shrimp, but these were
merely overlooked and were not inten-
tionally discarded. Some were also cast
aside because they were crushed, or
soft, having recently molted. From these
data it appears that when discarding
occurred, Z6 mm. carapace length was
the largest size normally discarded and
that at about 20 mm. carapace length
all shrimp were discarded.
The second aspect of this phase of
the study was to determine how often
discarding took place. Tows containing
some shrimp of 26 mm. or less (i.e.,
sizes which are ordinarily discarded)
were observed (table 5). On 23 tows the
fishermen intentionally discarded small
shrimp and on 177, they did not. The
majority of these cruises for which dis-
carding took place occurred during mid-
winter and fall. Table 5 also shows the
range and mean percentages of tows

in which shrimp less than 26 mm. were
discarded and not discarded. In discard-
ing tows, the mean percentage (obtained
by averaging the percentages of all
samples) was higher (58.1 percent of
shrimp were 26 mm. or less) than for
the no-discard tows (33.7 percent). On
some tows when no discarding took place,
as high as 93 percent of the shrimp
were 26 mm. or below.
When large numbers of small shrimp
(under 26 mm.) first appeared on the
grounds in September 1958, discarding
occurred. When it becanne apparent that
the small shrimp were in great abun-
dance, they were retained. During the
study period dealers indicated that all
sizes of shrimp could be marketed. In
September, samples taken from trash
in two heading houses produced no whole
discarded shrimp that were not soft or
damaged. Average size of two samples
were 22.9 mm. and 22.2 mm. carapace
length, the smallest individuals measured
about 18 mm.
SUMMARY
1. This report contains observations
on the relation between the size of Tor-
tugas pink shrimp and the depth of water
where they occur, on fleet concentrations,
on the grounds, and on the discards of
small pink shrimp.
2. Data on these aspects were gathered
from September 1957 to November 1958.
Two cruises per month were made each
month except June, October, and Novem-
ber 1958 to observe fleet activities and
to collect samples of shrinnp. Seven
flights were made over the grounds to
observe fleet concentrations. Additional
information on fishing effort was obtained
from logbooks.
3. The average carapace length of both
male and female shrimp taken during the
year increased with depth; however, a
size gradient irrespective of depth was
also apparent in a northerly direction
from the Keys. Whether the size-depth
relation was a function of seasonal dis-
persion of shrimp as they increased in
size, could not be determined.
During the period from Jvme through
November 1958, logbook reports from
14 boat& indicate that very little discard
took place. Data from approximately 645
tows (on the basis of three tows per
night) show discard occurring on only
17 tows, for an estimated total weight
of 138 pounds. Apparently small shrimp
are discarded only when few are caught,
and it is not worth the effort or expense
to ice them separately from the rest of
the catch.
4. The small shrimp first occurred on
the eastern and southeastern portions
of the grounds. Small shrimp were most
widely distributed on the grounds during
September through May 1958.
5. The highest catches, based on try-
net data, were made December 1957-
January 1958, and during March to June
1958. The highest catches were made
on the southern and eastern areas of
the grounds, generally in shallow water.
22
6. During December to June the largest
concentrations of vessels were located
on the eastern and southern portions of
the grounds. During the summer, the
fleet was more widespread.

APPENDIX
All tows from which samples of shrimp were obtained for the size -distribution
study are listed in appendix table 1. Not all tows provided adequate sannples of
shrimp; where this was the case, no average carapace length is provided. During
July and August 1958 (Cruises 16, 17, and 18), 28 tows were made with the try net
to locate the eastern boundary of the recurrence of algae. These tows are not listed.
Try net tows that were made simultaneously with main net tows are not listed.
