Özet
Catch productivity, catch composition, bycatch and discard rates of shrimp beam trawl were investigated between January 2003 and March 2004 in Marmara Sea. A total of 37 species which were captured by beam trawl during survey. The relative abundance in weight, respectively, were 51,3 % arthropoda, 30,9 % fish species, 15,5 % echinodermata, 1,3% mollusc. The deep water pink shrimp (Parapenaus longirostris) formed 50,8 % of the total catch. The length distribution of deep water pink shrimp ranged from 47 mm to 154 mm. Catch productivity in beam trawl fishery was calculated 10,1 kg/h. On average 0,42 kg discard, 0,62 kg incidental catch rate and 1,04 kg by-catch for 1 kg shrimp were estimated from beam trawl fisheries.
