Abstract
Flatfish gillnet selection curves for cresthead flounder Pleuronectes schrenki were estimated using cumulative probability distributions of the retention girth at length. Catch data were obtained from gillnets of six different mesh sizes and five different hanging ratios in March and July 1995 and March 1996 in Saroma Lake. Average body lengths showed significant differences with mesh sizes, but no significant differences were observed with hanging ratios. The retention girths in the Sechin's model were used as the girth at the insertion of the pelvic fin and girth between the insertion of dorsal fin and tip of proximal pterygiophore of the first anal fin ray. The estimated selection curves increased in peak width with increasing mesh size, and these corresponded with body length frequencies obtained from each mesh size.
