Abstract
In June of 1959-63 permanent marks were applied to 50-61% of 5 year-classes of wild brook trout (Salyelinus fontinalis) in 3.5 mile long, 12-acre Lawrence creek. Different marks were used in at least 3 of 4 stream sections each summer. Dispersal accross section boundaries was determined from subsequent recaptures of marked age-group 0 brook trout during annual September population estimates. Dispersal of 6-9 month-old fingerlings was directly correlated with their density. By mid-Sept. 10% of the surviving fingerlings had emigrated from their section of origin when their density in June was 548 per acre, and 36% had emigrated when their density in June was 6,323 per acre.This publication has 0 references indexed in Scilit:
