Determination of some biological characteristics of pike-perch (Sander lucioperca) distributed in Seyhan dam lake

In this study, the feeding, growth and reproduction characteristics of Sander lucioperca, one of the commercial and amateur fishing fleet target species in Seyhan Dam Lake, were investigated. Fish specimens were collected from catches using monofilament monofilament gill nets in Seyhan Dam Lake from September 2020 to August 2021. The obtained 378 pike-perch individuals were examined in the laboratory, and the von Bertalanffy growth parameters were estimated to be L∞=50cm,K=0,301781 〖year〗^(-1) and to=-0,04013 year, using the regression technique. Teleost, Odonat and Mysid were detected in stomach content analysis. It has been determined that teleost is a more important food group than other food groups in the nutrition of the species. The monthly variation of GSI values reveals that the spawning season of the species is in april and may.
