Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1991-1992, James A. Colvocoresses, Patrick J. Geer, Christopher F. Bonzek Jun 1992

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1991-1992, James A. Colvocoresses, Patrick J. Geer, Christopher F. Bonzek

Reports

Provisional annual indices of juvenile abundance have been generated from trawl survey data for five species of key recreational importance in the Virginia portion of Chesapeake Bay (spot, croaker, weakfish, summer flounder and black sea bass) and one species of secondary importance (scup) for the period 1988-1991. Only summer flounder catches resulted in an index that showed a consistent (upward) trend over the four years sampled, but the maximal value recorded for 1991 (2.8) was not statistically significantly higher than the prior year, in contrast to the previous increases observed. Atlantic croaker showed the greatest variability between years, with the …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1990-1991, James A. Colvocoresses, Patrick J. Geer

Reports

A recent analysis of the Virginia portion of the National Marine Fisheries Service Marine Recreational Fisheries Statistics Survey (VMRC 1985) showed that Virginia marine recreational catches were dominated by six species (spot, croaker, weakfish, black sea bass, summer flounder, and bluefish) which constituted over 85% of the total estimated catch by both numbers caught and weight landed. All of these species except bluefish heavily utilize the lower Chesapeake Bay as a nursery area for early juveniles which are highly vulnerable to bottom trawls.


Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1990, Christopher F. Bonzek, Patrick J. Geer, James A. Colvocoresses, Robert E. Harris Jr. Mar 1991

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1990, Christopher F. Bonzek, Patrick J. Geer, James A. Colvocoresses, Robert E. Harris Jr.

Reports

This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January through December, 1990. The trawl survey is a long term, broad scope monitoring program. Its primary goal is to produce annual indices of juvenile (young-of-year) abundance of commercially, recreationally and ecologically important marine and estuarine finfish and crustaceans. The objective is to provide indices of sufficient accuracy and precision for· both immediate resource !fianagement needs and long-term understanding of environmental influences on fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization by juveniles …
