Marmara Denizi'nde Kullanılan Karides Algarnasında Hedeflenmeyen Türleri Azaltmak İçin Kullanılan Izgara Panellerin Seçicilik Özellikleri

Considerable by-catch problems have occurred in the commercial beam trawl fishery targeted at deep water pink shrimp Sea of Marmara. In this study, grid systems were used to reduce untargeted catch and improve species' selectivity. By-catch reduction ratios trawls deployed with without compared by parallel hauling method. Selectivity values 20 mm bar spacing 24 mesh size cod-end also analyzed SELNET program. general, determined as 50.6% 56.9% terms number weight, respectively. The target (Parapenaus longirostris) same gear was found 23.1% 23.2% weight. model for rose shrimp, obtained according lowest AIC value, selectivity parameters L50 13.51 cm SR 4.76 cm. species were; = 8.99 5.56 These results indicated that usage benefits contribute sustainable catch-oriented fishing applications.
