چکیده

This study was carried out between September 2020 and March 2021 to determine the selectivity of monofilament gillnets used in pearl mullet, Alburnus tarichi (Güldenstädt, 1814), fishing Lake Van. The SELECT method applied selectivity. best model for mullet determined as log-normal model. optimum catch lengths with 20, 22 24 mm mesh sizes were calculated 21.69 cm, 23.84 cm 26.01 respectively. Catch per unit effort 10.03 kg/90 m/day at 20 mm, 15.91 12.99 mm. average 151 unit/90 110 According results length daily effort, using size more convenient sustainable

Selectivity of multifilament trammel nets of different mesh sizes on the red mullet (Mullus barbatus L., 1758) in Western Mediterranean, Turkey

Three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in Finike bay for red mullet (Mullus barbatus L., 1758). The sampling program was arranged during February to May 2012. Holt (1963) method was used for selectivity of trammel nets. Red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...
