Meat yields of crayfish caught from koçkale hunting area of Keban Dam Lake during reproduction period
This study was carried out to determine the meat yields of crayfish in Keban Dam Lake Koçkale Hunting Site during the breeding period.
Crayfish were hunted with pinter nets in May 2019 and brought to the Laboratory of Fisheries Faculty of Munzur University. Crayfish
were kept for 24 hours at -20°C for anesthesia. Then, the abdominal meat was extracted and weighed and the meat yield was determined by
proportioning it to body weight. Meat yield was 10.028% in male individuals, 13.346% in female individuals and 11.229% in all individuals.
A strong linear relationship was between the weights of crayfish and abdominal meat yields (r♂ = 0.828, r♀ = 0.770, r♂+♀= 0.751). It was
determined that the relationship between abdominal width and meat yield of female and male crayfish were close to each other according to
r values (r♂ = 0.757, r♀ = 0.722). However, it was observed that the linear relationship between the abdominal length of the females and the
amount of meat was stronger than the male subjects (r♂ = 0.524, r♀ = 0.736).
