Abstract
Several annual indices of juvenile abundance have been generated from trawl survey data for 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). No species has shown a continuous trend during the past fourteen years under the present sampling scheme. However, several species have revealed declines (spot, scup, and northern puffer) or increases (striped bass) in recent years. Results for the 2000 sampling season indicate significant declines over previous years for Atlantic croaker (2.40 times decrease), and the age 1 + components of white and channel catfish (2.29 and 2.66 fold decline, respectively). Significant increases were observed for striped bass and y-o-y white perch (9.92 and 6.78 fold increase, respectively).
