Abstract

Relative abundance indices which were near zero prior to 1976, increased dramatically (5-10 fold) from 1976 to 1981 in all regions studied. Subsequently, abundance dropped from 1982-1987. Gonadal recrudescence begins in late July and males appeared to mature earlier in a reproductive season than females. Maximum age was 5 yr. Age at 50% maturity was age II for all regions in spring. Comparison of Von Bertalanffy growth curves suggests a decline in length and age with declining latitude. -from Authors
