Abstract
Abstract Striped bass Morone saxatilis were collected from mixed-stock populations in New Jersey, New York, Connecticut, Rhode Island, and Massachusetts coastal waters in spring and fall 1983–1986 for purposes of stock identification. Four morphometric characters and abundances of six eye lens proteins were used in a growth-invariant discriminant function analysis for classification into Hudson River stock or Chesapeake Bay-Roanoke River group. Correct classification rates were 76 and 80% for the Hudson River stock and the pooled Chesapeake Bay-Roanoke River group, respectively. The contribution of the Hudson River stock to the coastal populations varied between 14 and 89%, depending upon season and sampling location (state). Several factors influenced stock composition estimates, including year-class or size composition of the sample, geographical distribution of sample sites, sampling period duration, and season.
