Abstract

The objective of this study has been to develop a proportionally weighted Baywide young-of-the-year Chesapeake Bay striped bass index which incorporates data from all major nursery areas of the Chesapeake Bay. In doing so three approaches were used. The first entailed simple computation of both arithmetic and geometric indices. These were computed for historical continuity. The second approach involved a weighting by the commercial landings from each river during the spawning seasons from 1973-1981. The third approach used the area of the spawning grounds and distance of shoreline adjacent to the nursery grounds. Finally, an effort at validation was made using Maryland and Virginia fishery-independent CPUE of three-year old fish.
