Abstract
A total of 3,892 striped bass were tagged and released in the Fall 1988 and 1,316 fish in the Spring 1989 on the Rappahannock River. In the Fall, 77.6% of the tagged striped bass were less than 400 mm FL. In contrast, 81.5% of the fish were 400 mm FL or greater in the Spring. The available striped bass stock in the Fall is more vulnerable to fishing than is the available stock in the Spring. Recaptures per net day of tagged striped bass in pound nets in the Fall 1987 were seven times greater than in the Spring 1988, and 113 times greater in the Fall 1988 than in the Spring 1989. The latter value, however, is inflated to some degree because of recurring high river flows in the Spring 1989. With the occurrence of frequent freshets, the fish moved downstream below the location of the nets, thereby periodically reducing their availability.
