Abstract

This study aimed to determine the selectivity of multifilament trammel nets in pearl mullet, Alburnus tarichi (Guldenstadt, 1814), and fishing in Lake Van (east of Turkey). In line with this objective, the multifilament trammel nets with 20, 22 and 24 mm mesh sizes were tested in trials. The current study was conducted between September 2019 and April 2020. Thirty-four fishing operations were conducted in the 40-60 m depth range. The "SELECT" method was applied to determine the selectivity parameters. According to the results, the lengths of the optimum catching using nets with 20, 22 and 24 mm mesh sizes were calculated as 20.76 cm, 22.07 cm and 24.11 cm, respectively. The highest average CPUE in weight was 24 mm (6.007 kg/ 100 m / day). Considering the data obtained in the present study, the best optimum catch length and CPUE values for pearl mullet fishing were determined in multifilament trammel nets with a 24 mm mesh size. In conclusion, this study suggests that using a 24 mm mesh size in a lake for pearl mullet fishing will benefit fish stocks and local fishermen.
