Determination of meat productivity and biochemical composition of freshwater lobster (Astacus leptodactylus Eschscholtz, 1823) in Lake Tatlı and Lake Gici from Bafra Fish Lakes

Abstract

In this study, it was aimed to determine the meat productivity and biochemical compositions of freshwater lobster (Astacus leptodactylus Eschscholtz, 1823) in Tatlı and Gıcı Lakes from Bafra Fish Lakes. The research was carried out by monthly fishing of freshwater lobsters using Pinters at the stations determined between November 2018 and October 2019. While 105 of the 242 freshwater lobsters caught in Tatlı Lake were female and 137 male, 87 of the 216 freshwater lobsters obtained in Gıcı Lake were found to be female and 129 as male. In the study, the average total length and an average weight of freshwater lobsters in Tatlı Lake were determined as 10.27±0.09 cm and 33.76±0.88 g, respectively. In Lake Gıcı, the mean total length was 10.44±0.41 cm and the average weight was 37.15±1.91 g. While the total meat yield of female and male lobsters obtained from Tatlı Lake was 15.27±0.51% and 15.13±0.64%, respectively, the total meat yield of female and male lobsters obtained from Gıcı Lake was 15.18±0.59% and 15.51± 0.69.%, respectively. Crude protein, crude oil, crude ash and moisture values ​​were determined as 16.10±0.23, 0.59±0.39%, 1.60±0.24% and 81.60±0.26%, respectively, in lobsters obtained from Lake Tatlı. In lobsters, it was determined as 15.49±0.13%, 0.61%±0.06%, 1.57±0.36% and 82.24±0.19%, respectively.
