Abstract
Capture‐recapture methods were used to estimate the population size and density of American eels Anguilla rostrata in a 1‐km section of a tidal creek during May. Of 645 American eels tagged over 6 d, 282 were recaptured at least once. Adjusted Petersen, Schnabel, and computer‐modelling techniques produced population estimates ranging from 728 to 928 American eels, corresponding densities being 182–232 fish/hectare, and an approximate biomass of 50.5 kg in the 4‐hectare study site. Capture location records indicated a mean home range of 1.04 hectares for 82 American eels recaptured two or more times. Combined with other short‐ and long‐term observations, American eels at this estuarine site appear to exhibit relatively restricted movements.This publication has 6 references indexed in Scilit:
