Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1994-1995, Patrick J. Geer, Herbert M. Austin, David N. Hata
Reports
Annual indices of juvenile abundance have been generated from trawl survey data for several species of key recreational importance in the Virginia portion of Chesapeake Bay (spot, croaker, weakfish, summer flounder, black sea bass and striped bass, white and channel catfish) and four species of secondary importance (scup, white perch, northern puffer, and silver perch) for the period 1988-1995. No species has shown a continuous trend during the seven year period, although several species have revealed declines (spot, scup y-o-y white perch, northern puffer) or increases (Atlantic croaker and striped bass) in recent years. Spot has shown the largest decline …

Reports
The Virginia Institute of Marine Science (VIMS) has conducted a trawl survey dating back to 1955. Over these forty years methods and objectives have varied according to funding sources and state and/or federal mandates. The present thrust of the program is to provide juvenile indices of relative abundance for recreationally, commercially, and ecologically important finfish and invertebrates. These measures of juvenile abundance are widely used as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of juveniles (age-0) have proven to be a reliable and early indicator of future year-class strength. A review of previously …
