Juvenile Seine Surveys of the Chesapeake Bay from the Virginia Institute of Marine ScienceEntry ID: VIMS_SEINE_SURVEY
Abstract: The Virginia Institute of Marine Science initiated the juvenile
striped bass seine survey in 1967. An index of abundance has been
calculated every year since 1980 and is the second longest continuous
striped bass index in the U.S. It and others like it are a valuable
tool used in the formation of management regulations by the Atlantic
... States Marine Fisheries Commission (ASMFC) along the east coast of the U.S.
The primary objective of the survey has been the monitoring of the
relative annual recruitment success of juvenile striped bass in the
spawning and nursery areas of lower Chesapeake Bay in order to create an
index of abundance for the species. This estimation of juvenile
striped bass in Virginia waters is part of a coast-wide sampling program of
striped bass recruitment conducted from New England to North Carolina
under the coordination of the ASMFC.
Currently, this survey samples waters from eighteen historically
sampled sites (index stations) and twenty-two auxiliary sites along
the shores of the James, York and Rappahannock river systems.
Field sampling is conducted during five approximately biweekly
sampling periods from July through mid-September. At each station,
collections are made by deploying a 100 ft. (30.5 m.) long, 4
ft. (1.22 m.) deep, 1/4 in. (0.64 cm.) bar mesh minnow seine
perpendicular to the shoreline (either until the net is fully extended
or a depth of approximately four feet is encountered) and then leaving
the onshore brail in a fixed position while pulling the offshore end
downcurrent and back to the shore, resulting in the sweeping of a
quarter circle quadrant.
In 1993, the VIMS Juvenile Bluefish Seine Survey began as an extension
of the VIMS Striped Bass Seine Survey. Preliminary sampling began
in the fall of 1993 and encouraging results led to its funding in
early 1994.The primary objective of the survey is to monitor trends in
abundance of bluefish along the beaches of Virginia's Eastern Shore
and southside Virginia in order to develop a viable index of
abundance. This information is then disseminated to government agencies and
incorporated into the fisheries management plan for bluefish in the
Mid-Atlantic Bight. Additionally, a number of other recreationally and
ecologically important finfish species are monitored and include
pompano,crevalle jack, striped anchovy, striped killifish, Atlantic
thread herring, rough and Atlantic silverside, summer flounder, black
drum, red drum, and spotted seatrout. Since the project is still in
the early stages and those juvenile fish from the early samples have
not reached maturity, it is difficult to assess the predictive value
of the index.
Currently, juvenile bluefish seine field sampling is conducted during
thirteen approximately biweekly sampling periods from April through
October at the southside beaches and the Eastern Shore of Virginia.
At each station,collections are made using a 100 ft. long x 6 ft.
deep x 1/4 inch bar mesh bag seine.
When sample sizes are large, a subsample of at least 25 individuals
are measured and the remainder counted.
For both seine surveys, the atmospheric and station data
are also recorded and include: salinity, temperature, pH, dissolved
oxygen, time, air temperature, wind speed and wind direction. All fish
captured, except those preserved for genetic or life studies are
returned to the water at the conclusion of sampling.
