Striped bass Morone saxatilis from the Upper Chesapeake Bay were studied to determine if discrete populations exist. Spawning fish and juveniles in five rivers, the Patuxent, Potomac, Choptank, Elk, and Nanticoke were sampled. Discontinuous polyacrylamide gel electrophoresis separated the serum proteins for population analysis. Five proteins, which were not related to the age, sex, or time of collection of striped bass, were used to discern populations. The Elk River striped bass are very distinct. Both the Choptank and Nanticoke are also distinct but show some connection with the Patuxent and Potomac striped bass. The Patuxent and the Potomac striped bass could not be distinguished from each other on the basis of the five proteins studied. The geologic evidence supports the theory of population formation for striped bass in the Chesapeake Bay. Management implications of the striped bass populations are also discussed.
