National Marine Fisheries Service, Special Scientific Report — Fisheries
The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic
distribution of fisherv- resources, to understand and predict fluctuations in thequantity and distribution of these resources, and to establish levels
for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing
grounds, development and enforcement of domestic fisheries regulations, sur\eillance of foreign fishing off United States coastal waters, and the
development and enforcement of international fishery agreements and policies. NMFSalsoassists the fishing industry through marketing service
and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on
various phases of the industry.
The Special Scientific Report — Fisheries series was established in 1949. The series carries reports on scientific investigations that document
long-term continuing programs of NMFS. or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery
problems. The series is also used as a medium for the publication of bibliographies of a specialized scientific nature.
NOAA Technical fleports NMFS SSRF are available free in limited numbers to governmental agencies, both Federal and State. They are also
available in exchange for other scientific and technical publications in the marine sciences. Individual copies may be obtained (unless otherwise
noted) from D825, Technical Information Division. Environmental Science Information Center. NOAA, Washington, D.C. 20235. Recent SSRFs

Midwater Invertebrates from the Southeastern Chukchi
Sea: Species and Abundance in Catches Incidental to
Midwater Trawling Survey of Fishes,
September-October 1970
BRUCE L. WING and NANCY BARR'
ABSTRACT
Midwater invertebrates were collected in the southeastern Chukchi Sea. A 1.8-m Isaacs-Kidd
midwater trawl was used at 20 stations to collect 81 semiquantitative samples; a :!-m otter trawl was
used at one station to collect two qualitative samples. Data tables list the species collected and their
numbers, size range, and displacement volumes for the midwater trawl stations and a species list only
for the otter trawl station. One hundred three species of invertebrates were identified from the mid-
water trawl samples, and ,33 species were identified from the otter trawl samples. Amphipods were the
most diverse group (40 species) and decapod shrimps the next most diverse (14 species). Numbers of
species in a sample varied from 4 to 40 (mean 17). After removal of jellyfishes, the most important con-
tributors in numbers and volume to the catches were euphausiids and mysids.
INTRODUCTION
The Western Beaufort Sea Ecological Cruises (WEB-
SEC) were a sequence of oceanographic cruises spon-
sored by the U.S. Coast Guard to assess the Alaskan arc-
tic marine environment and biota before major indus-
trial development. The Coast Guard enlisted the efforts
of federal, state and university research groups for the
program, and the National Marine Fisheries Service con-
tributed to the first three cruises with studies of
zooplankton, midwater invertebrates, and fishes.
The intent of the first cruise, WEBSEC-70, which took
place during September and October 1970, was to ex-
amine the arctic coast from Barrow eastward to Barter
Island. Extremely heavy ice conditions in mid-Septem-
ber 1970 prevented the Icebreaker Glacier from working
in the Beaufort Sea; therefore, an alternative area, the
southeastern Chukchi Sea between Point Lay and Cape
Lisburne (Fig. 1) was surveyed between 25 September
and 17 October. Preliminary results of physical,
chemical, geological, and biological investigations for
WEBSEC-70 were reported by Ingham et al. (1972); and
reports were later published by Quast (1974) and Wing
(1974).
This report presents data on the invertebrates taken in
midwater trawls made to collect fishes from 25 Septem-
ber to 17 October 1970. The data are presented in tabular
form and are not interpreted, although some apparent
sampling anomalies are discussed. The tables provide a
list of species found, numbers of individuals taken, and
linear size range and displacement volume of the

specimens of each species. These data are the first
attempts to quantitatively assess macroplanktonic and
niicronektonic invertebrates in the southeastern Chuk-
chi Sea.
METHODS
A 1.8-m Isaacs-Kidd midwater trawl was used to
sample at 20 stations for a total of 81 tows (Fig. 1, Ap-
pendix Table 1). The trawl had a forward section of 38-
mm bar mesh, a rear section of 6-mm bar mesh, and a
cod end of 3-mm bar mesh. Cross-sectional areas were
calculated to be 2.87 m' at the mouth, 1.55 m' at the
beginning of the 6-mm mesh, and 0.13 m- at the begin-
ning of the 3-mm mesh. The depth of tow was recorded
by a bathykymograph attached to the bottom of the
depressor. Tows were standardized for a length of 3.7 km
at an estimated vessel speed of 4 knots. At least four tows
were made at each of the 20 stations, two on one bearing
and two on the reciprocal bearing. Trawling was general-
ly done at night in areas relatively free of ice. The choice
of sampling depths was dependent on water depths and
on whether or not the samples were intended to be
replicates or were to examine depth distributions (Quast
1974).
At one station (No. 8— Fig. 1) two trawls were made
with a 3-m, 38-mm mesh otter trawl (shrimp try net) to
collect bottom fishes and invertebrates.
Large scyphomedusans and most hydromedusans
taken in the trawls were discarded in the field after the
sizes and numbers of each species of scyphomedusan and
the volumes of hydromedusans had been recorded. The
other invertebrates were preserved in 5'"c Formalin.
In preparation for examining the invertebrates in the
laboratory, formalin was washed from the samples and

they were stored in 40'f isopropyl alcohol. Each sample
was examined first in its entirety for rare species. For
small samples, total counts were made for each species of
invertebrate, and maximum and minimum size ranges
were recorded. When large numbers of euphausiids or
mysids were present, the collections were subsampled
with a Folsom plankton splitter (McEwen et al. 1954).
The subsamples always contained more than 500 in-
dividuals.
Identifications (to species when possible) were based
on the following taxonomic references: Banner (1948a
1948b, 1950, 1954); Barnard (1958, 1962a, 1962b, 1962c
1964, 1973); Boden et al. (1955); Bowman (1973, 1960)
Brodskii (19.50); Coe (1904, 1905); Dawson (1971); Dun
bar (1954); Gurjanova (1951); Holmquist (1959, 1965)
Leung (1971); G. E. MacGinitie (1955); N. MacGinitie
(19.59); Naumov (1960); Rathbun (1904); Sars (1895,
1900); Shoemaker (1955); Vanhoffen (1906); and Zim-
mer (1926). Except for decapod shrimps, lengths are
greatest body lengths to the nearest millimeter and do
not include antennae, rostra, or tentacles. Decapod
shrimp lengths are for the carapace (insertion of eye to
dorsal posterior margin). Displacement volumes to the
nearest 0.5 ml were taken on the drained lots of each
species sorted from a sample. The volumes were
measured with 10-, 25-, 100-, or 500-ml graduated
cylinders. All sorting and measuring was done 1-4 yr after
the specimens were collected; thus shrinkage due to
preservation was stabilized. Displacement volumes were
obtained only for samples processed in the last 4 mo of
sorting.
RESULTS
The 81 samples from the 20 midwater trawl stations
contained 103 specimens of invertebrates (Table 1).
Amphipods had the greatest number of species (35) and
decapod shrimps the second largest (14). The number of
invertebrate species per sample ranged from 4 to 40
(mean, 17). The scyphomedusans and hydromedusans
discarded in the field contributed most to the volume of
the catches. In the preserved material, euphausiids and
mysids were the most abundant invertebrates and the
major contributors to the biomass (Appendix Table 2).
Thirty-three species of invertebrates were identified
from the two samples taken by the 3-m otter trawl at
station 8 (Table 2). The list of invertebrate species from
station 8 plus the benthic invertebrates taken in the mid-
water trawl samples supplement the more extensive lists
of benthic invertebrates from the southeastern Chukchi
Sea given by McCauley (1964), Sparks and Pereyra
(1966), and Naidu and Sharma (1972). Three species of
gastropods, 4 bivalves, 2 mysids, 2 isopods, 12
amphipods. 9 decapod crustaceans, and 1 ascidian were
collected by the otter trawl.
DISCUSSION
The three sizes of meshes in the Isaacs-Kidd mid-
water trawl used in the sampling were 3-mm cod end, 6-
mm rear section, and 38-mm forward section. Some of
the invertebrates captured were so small that many of
them undoubtedly passed through the larger meshes. Al-

though the resulting catches should be considered only as
semiquantitative, they do provide indicators of the kinds
and general quantities of midwater invertebrates present
in the southeastern Chukchi Sea.
The terms mesoplankton, macroplankton, micronek-
ton, and benthos may be applied to various grouping of
invertebrates collected with the Isaacs-Kidd midwater
trawl in the Chukchi Sea during WEBSEC-70. None of
the terms are precisely defined, but they provide criteria
for evaluation of catches by those who may wish to com-
pare the species and quantities reported in Appendix
Table 2 with other sets of data.
Mesoplankters are zooplankters quantitatively retain-
ed by a 0.2-mm mesh net and having a total body length
less than 10 mm. Large mesoplankters are those with a
body length greater than 1 mm. The midwater trawl used
during WEBSEC-70 did not quantitatively retain large
mesoplankters, as evidenced by the low frequency and
small numbers of copepods Calanus finmarchicus s.l.
and Eucalanus bungii and the chaetognath Sagitta
elegans in the catches. These mesoplankters were widely
distributed and abundant in plankton samples taken
with a 0.57-mm mesh plankton net during the same
cruise (Wing 1974).
Animals of the macroplankton and micronekton are
large enough to be identified with the naked eye. There is
no upper size limit and the lower size limit (5-10 mm
long) is dependent on the taxa involved and the knowl-
edge of the researcher. Animals of the micronekton are
10-100 mm long and can swim well enough to avoid stan-
dard 1-m plankton nets. Because the swimming ability of
crustaceans, cephalopods, and fishes increases with size,
macroplankton and micronekton are not precisely defin-
ed or clearly separable categories. Within the size range
of macroplankton and micronekton, the midwater trawl
used during WEBSEC-70 would collect quantitatively
only the large scyphomedusans and the hydromedtisan
Cuspidella mertensii. Although herding occurs, much of
the macroplankton and micronekton passes through the
6- and .38-mm meshes at the front of the net. Many of the
hydromedusan Aglantha digitale, the euphausiids, and
the mysids undoubtedly passed through the net, al-
though these were the most abundant organisms in the
catches (Appendix Table 2). The retention of
macroplankton- and micronekton-sized medusans,
amphipods, mysids, euphausiids, and shrimps by the
midwater trawl used during WEBSEC-70 indicates that
they were quite abundant and important in the trophic
structure of the area but does not measure their abun-
dance.
Many of the species collected by the midwater trawl in
the Chukchi Sea are considered to be benthic animals,
i.e., they live on (epibenthos), in (endobenthos), or just
off (hyperbenthos) the bottom. Many of the benthic
animals, especially polychaetes, mysids, cumaceans,
gammarid amphipods, and shrimps, may leave the bot-
tom at night and become part of the macroplankton and
micronekton. Except for stations 8 and 14 (Table 1), all
sampling was at night: consequently some benthic
animals were well represented in the collection.
The shallowness of the area (22-54 m) sampled by
WEBSEC-70 contributed to the occurrence of benthic
animals in the midwater trawl catches. Benthic animals,
which rise off bottom at night, are likely to contribute
more to the macroplankton and micronekton in shallow
waters than in deeper waters. Additionally, wave-in-
duced turbulence and ice rafting may have placed in sus-
pension some endobenthos (i.e., benthic snails, sipun-
culids, and echiuroids), which would not normally be off
bottom. The net struck bottom only on station 88.
Samples from that station contained two species of snails
(Margarites sp. and Natica clausa), a clam {Nucuia
tenuis), adult hermit crabs {Pagurus sp.), and brittle
stars (Ophiuroidae) in addition to more usual plank-
tonic species (Table 1, Appendix Table 2).
SUMMARY
One hundred three species of invertebrates were taken
in Isaacs-Kidd midwater trawl samples from the
southeastern Chukchi Sea during WEBSEC-70. Thirty-
three species were taken by otter trawl. Numbers of in-
vertebrate species in a midwater trawl sample varied
from 4 to 40 (mean, 17). Amphipods were the most varied
group (40 species) and shrimps the next most varied
group ( 14 species).
After removal of hydroid and scyphozoan jellyfishes,
euphausiids and mysids contributed the most to the
biomass and numbers of the midwater invertebrates
retained by the midwater trawl.
