Monofilament gillnet selectivity parameters for European chub (Leuciscus cephalus L.1758) in Atikhisar Reservoir, Canakkale, Turkey.

Selectivity parameters of gillnets used for fish catching are very important for fisheries management in lakes. The main purpose of the present study was to estimate the selectivity parameters of monofilament gill nets mesh size of 56, 64 and 72 mm (stretched mesh size) used for European chub (Leuciscus cephalus L.1758) in Atikhisar Reservoir, Canakkale, Turkey. The indirect method proposed by Holt was used for the estimation of the selectivity parameters. The common selection factors and common standard deviation of monofilament gill nets were determined as 4.25 and 2.37, respectively. For sustainable fisheries of European chub, the minimum mesh size of monofilament gill nets must be greater than 47 mm stretched mesh size.
