Investigation of the Selectivity of Multifilament and Monofilament Gill Nets on Pike perch (Stizostedion lucioperca (L., 1758)) Fishing in Lake Beyşehir

[摘要] In this study, carried out in Lake Beyşehir, the selectivity of multifilament and monofilament gill nets used for pike perch fishing were investigated. Multifilament gill nets with 5 differenet mesh sizes and monofilament gill nets with 6 different mesh sizes were used during experimental fishing from October 1994 ve May 1996. According to the results, the common selection factor of multifilament gill nets was calculated to be 4.67 and 4.70 for monofilament gill nets.
