This popular consumer product has been the subject of much recent research. Crayfish were caught from Cernek lake in October-November and May-June 2021-2022 using a pinter. A total of 400 crayfish were included in the study, of which 224 were male and 176 were female. Important data on crayfish under and above 35 g were obtained. The average meat yield was 15.79% in the period October-November and 15.30% in the period May-June. The average of the total meat yield was 15.55%. As a result of the crayfish meat yield study, 100 g of consumable meat was obtained from approximately 13.17 individuals. Carapace length was found to have a statistically significant coefficient in the determination of total meat yield. The results of the study will support demand increases in the local market and have a beneficial impact on aquaculture businesses.eninfo:eu-repo/semantics/openAccessCrayfishPontastacus leptodactylusmeat yieldseasonsArticle53110.1080/09712119.2025.25310682-s2.0-105010579801Q2WOS:001526984100001Q20000-0001-9109-2921
