The Northeast Fisheries Center assessed the status of the Atlantic herring
stocks (G~lf of Haine and Georges Bank) with results serving as input to fishery
management plans.
A remote aerial surveillance program designed to locate schools of migrating herring was conducted by Zapata Corporation during April-May in the Gulf of
Maine and on Georges Bank.
A bottom-trawl survey was conducted durin~ September by the USSR R/V
VIA~DRA on Georges Bank to locate concentrations of spawning herring.
Herring gonads were collected from the Gulf of Maine stock for a new
fecundity study.
Herring ta~ging was conducted in coastal Maine waters by·the State of
Haine Department of Marine Resources.
In the eastern Gulf of t1exico, age, grOl~th, and mortality of coastal
herrings were studied by E. D. Houde and S. A. Berkeley, University of Maryland
and University of r1iami. Objectives are to esti'··,Jte growth and mortality of
several species, including Sardinella anchovia, Opisthonem~ oglin~, and
Decapterus punctatus, from which yield models will be developed to estimate
potential of these fishes to sustain major directed fishing effort.
Hackerel
The Northeast Fisheries Center provided an updated assessment of the
of the Atlantic mackerel stock (Cape Hatteras to Newfoundland) for use
in the amended fishery management plan for 1981-82.
Length and age samples were collected from the Spring 1980 recreational
fishery for mackerel in the New Jersey - New York area. Commercial, recreational, and research samples of mackerel otoliths were aged for use in the
assessment.

Bluefish
The :tortheast Fisheries Center updated an earlier assessment of the
status of bluefish along the Atlantic coast of the US for use in preparing a
fishery management plan for the species. The assessment included an estimate
of maximum sustained yield determined from a generalized stock-production
model.
Buttern sh
The Northeast Fisheries Center produced an update on the status of
butterfish for use in amending the fishery management plan for 1931-82.

USA
The tlortheast Fisheries Center completed an analysis vlhich atter.1pted to
estimte the maxil'1u;n sustained yield of pelagic sharks in the Western ~lcrth
Atlantic and the Gulf of Mp.xico based on international re~orted and estimated
catches and fr~~ a wide variety of fisherics by-catches and catch-per-unit
effort from the Japanese tuna longline fishery. The results from this analysis
provided in~ut to existing and proposed fishery management plans for sharks.
Ir: 1980, 5,236 sharks representing 34 species ~ere tagged and released
under tr,e National t-larine Fisheries Service cOJperative shark-taggir.g program.
In acdition. 253 teleosts of 11 species were tagged. Volunteer taggers
atcounted for 95:' of the releases.
Research cruises I,ere conducted aboard two foreign vessels (R/V WIECZnO
frO.ll Gdynia, roland, and JA:lE R from lockeport, :bva Scotia) and two US vessels
(BIRO OF PASS,'\GE from ~Ioods 1I01e, r'lassachusetts, anJ 80:;:;,\ LEE from Highlands,
New Jersey). Areas of operation during the cooperative foreign cruises in
f·larch and August extended from the offings of Oaytona Geach, Florida, northward
alcng the edJe of the continental shelf to Hydro~rapher Canyon on the southern
margin of Georges Bank. The purpose cf the cruises was to tag sharks and
other lal'ge gamefish for migration studies and to collect biological data for
life history stucies Cf sharks and swordfish. The primary fishing method was
pelagic lon~lines except aboard the BIRO OF PASSAGE wh~re chumming, handlines,
and harpoons were employed. All fish captured were tagged (237) or taken on
board for studies of shark food habits, age and growth, and re~roduction .
. Re~roductive information was collected from a total of 54 sharks. A prime
objective of the SIRJ OF PASSAGE cl'uise was to study the digestion rate in the
blue shark with the use of sonic telemetry. The work was done in cooperation
with Dr. Frank Carey of the Woojs Hole Oceanographic Institution. The sonic
tracking experi~ents provided first quantitative information on blue shark
feeding rates under natural conditions. To date, 523 stomach samples have
bee~ analyzed by area (inshore, less than 50 fathoms; offshore, greater than
50 fathoms) and for sexual differences with respect to the type and a~ount of
food they contained.
•
Swordfish
Age determination and ecology 01' South Carolina swordfish were investigated by J. M. Oean and C. Wilson, ~niversity of South Carolina, to describe
otoliths and determine the age of all life stages of sl,ordfish, and to correlate such esti~ates with those obtained using fin spines. In addition,
~
biological data on diet, reproductive states, and fecundity are being collected.
The fishery and biology of broadbill swordfish were investigated by E. O.
Houde, S. A. Berkeley, D. P. deSylva, E. 1rby, and J. Jolley, University of
Miami and Florida Oepartment of Natural Resources, to assess the stock,
investigate its biology, and make management recommendations based on c011ection of catch-effort statistics and biological data.
a
Bluefin tuna
Bluefin tuna fishery-oceanography in the Gulf of r'1exico and western North
Atlantic were investigated by F. Wil1ia~s, tiniversity of t1iami, to determine
how tuna availability varies as a function of ocean productivity by using both
satellite remcte sensing and ground truth data.

Sailfisl1
The Florida sailfish, lstiophorus platypterus, fishery was monitored by
E. lrby, Florida Department of Natural Resources, with the objective to
assess stock abundance and the fishery through long-term monitoring of catch
and effort.
•
Striped bas2
An assessr:ent of larval stocks of striped bass in the Potomac estuary was
undertaken by F. D. Martin and E. Setzler-Hamilton, University of Maryland,
with the objective to estimate larval abundance and correlate it with distribution and abundance of larval food and predators.
King mackerel
Migrations and stock identification of king mackerel, Scomberomorus
were studied by R. Williams and C. Godcharles, Florida Department of
IJatura 1 Resources. Objectives are to determine seasonal migration patterns
and to atte~pt stock identification through tagging studies. The stock was
studied by H. Arnold of the saffie Department, with the objcctive to use electrophoresis in an isozyme analysis to distinguish stocks from the southeastern US
and Gulf of Mexico.
cava~,
Round scad
The life history of round sCdd, Decapterus punct~~, in the South Atlantic
Bight was studied by S. Hales, College of· Charleston, South Carolina. The
objectives are to: (1) determine distribution and abundance based on trawl
catch ddta, (2) estimate ages and growth rates from otoliths, (3) detcrmine
,food habits, and (4) investigate reproductive biology.
Ecosystem Dynamics and Food Chain Projects
•
Further refincments were made in the energy budget for Georges Bank,
particularly for zooplankton production estimates; and comparisons of production at all trophic levels were made between Georges Bank, the North Sea,
and the tlova Scotian Shelf. Work continued on developing estimates of sizerelated prey selection and food consumption in fishes on Georges Bank, and
progress to date was summarized in several documents presented at the 1980
lCES meeting. Daily rations were estimated for silver hake and cod, using a
model based on an exponential digestion process, with results falling between
upper and lower theoretical limits of food consumption for these species.
These data were used in preliminary testing of a multispecies model designed
to explore the importance of predation on recruitment fluctuations in multispecies fish communities.
A monograph was completed on the ecology of fishes in the Middle Atlantic
Bight (Cape Hatteras to Cape Cod), including life history synopses of 43
species of fish and shellfish, abrief zoogeographic description of the
finfish co~munity, and an overview of the changes in fish populations in
relation to fishing, temperature trends, and pollution.

Pelagic fish in general
The Miami Laboratory, Southeast Fisheries Center, conducted an ichthyoplankton cruise in the Gulf of r·lexico from February 25 to t·larch 27, 19200. The
purpose of the cruise was to collect tuna, scombroid, and other important
commercial and recreational fish larvae for studies on development, ab'mdance,
and distribution. The material was collected :Jsing bongo and neuston nets
from RjV QREGDrl 11. The ichthyoplankton sampIes were sent to the Polish
Sorting Center for sorting to be cODpleted by early 1931. A total of 102
stations were made throughout the Gulf of Mexico.
Physical oceanographi: data were collected by cooperating scientists from
the University of lliami. These data included continuous surface te~peratures,
8 bottle hydrocasts, and secchi disk and light transmission measurements at
each ichthyoplan!<ton station. Cooperating scientists from Texas A&t·! Unhersity
studied primary prod~ctivity and ~easured chlorophyll-a,b,c. suspended solids.
phytoplankton. and nutrients.
Additional Southeast Fisheries Center research included a large-scale
tagging expe~iment conducted on bluefin tuna juveniles off the northeastern
coast of the US in June. The purpose of this study is to obtain population
parameters necessary for assessment studies. Cooperative tagging studies of
billfish continued in 1930.
Comparison of the bioenergetics of feeding in two plankton-feeding fishes.
menhade'1. B. tyrannu5, and herring. Clu::ea harengus. was undertaken by Ann an.:!

planktivores (mel~haden) differ Trom pa.-ticle-selectors (herdng) in relation
to food use and efficiencies.
An estimation of early life histcry vital parameters of marine fishes,
and development of larval mortality models. was undertaken by S. Saila.
University of Rhode Island.
An assessment of the population dynamics of important commercial or
recreational fish of Chesapeake Bay is being carried out by B. J. Rothschild,
University of Maryland, using catch-and-effort statistics to obtain preliminary
stock assessments of several species, including striped bass. bluefish, river
herring, Ai"erican shad, and white pereh.
A comparison of larval food and condition among striped bass, white pereh,
and Clupeidae spp.in the Potomac estuary is being made ~y E. Setzler-Hamilton,
F. D. Martin, G. E. Drevlry. and J. A. t·lihursky, University of Maryland, to
deter~ine larval food habits, compare them among species, assess larval condition, and relate it to abundance of zooplankton used as food.
forecasting commercial finfish landir.gs and crab catch from Maryland
estuarine waters is being done by R. E. Ulanowicz, University of Maryland. to
develop algorithms that rely on environmental correlates to predict the magnitudes of annual catches of several species, including striped bass, alewife,
bluefish. butterfish. menhaden, scup, American shad, gizzard shad, and white
perch.

Pamlico Sounds: (2) stock assessment of striped bass in Albermarle and Pamlico
Sounds and the Cape Fear River; (3) offshore assessment (trawling surveys) of all
anadromous species, from Cape Lookout to Chesapeake Bay; and (4) experimental
stocking of striped bass to increase population size. All of these programs
are carried out with field sampling, juvenile abundance indices, commercial
catch statistics, and biological data on the catch composition.
The relationship of upwelling events to spawning by pelagic fishes is
being investigated by T. Targett, Skidaway Institute of Oceanography. Objectives are to use satellite remote sensing and gro~nd truth data to assess
primary production, zooplankton production, and larval abundance, and to infer
how spawning by fishes, particularly menhaden and bluefish, is linked to
oceanographic events.
Temporal and areal distribution of scombrid larvae in the Florida Straits
was investigated by K. Burns, Florida Department of Natural Resources, to
determine seasonal spawning activity by tunas and mackerels in relation to
oceanographic factors.
The role of Mississippi Sound in recruitment of commercial and recreational
fish stocks was investigated by S. Richardson, University of Mississippi, Gulf
Coast Research Laboratory, to assess potential recruitment of many species by
monthly larval abundance surveys .
