Özet
This study investigates the differences in the selective properties of a 40 mm nominal PE, 36 and 44 mm nominal PA codends. The experiments were carried out in Izmir Bay in the Eastern Aegean Sea between 4 February 2002 and 22 March 2002. A conventional bottom trawl was operated onboard R/V Egesuf. Selectivity data were collected for red mullet (Mullus barbatus). annular sea bream (Diplodus annularis), picarel (Spicara smaris) and common pandora (Pagellus erythrinus) by using hooped covered codend method. Selectivity parameters were obtained by using logistic equation with the maximum likelihood method and by taking into account between-haul variation.
