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

Marmara Denizi'nde derin su pembe karides avcılığında önemli derecede yan av sorunu yaşanmaktadır. Bu çalışmada hedef türün haricinde istenmeyen tülerin avcılığını azaltmak için ızgara panel sistemleri kullanılmıştır. Izgara panel sistemi yerleştirilen ve ızgara panel sistemi olmayan algarna takımlarının yan av yakalama oranları paralel çekme yöntemi ile karşılaştırılmıştır. 20 mm çubuk aralığı ızgarası ve 24 mm ağ göz açıklığına sahip torba seçicilik değerleri de SELNET programı ile analiz edilmiştir. Genel olarak ızgara panel kullanılan algarna takımının yan av azaltma oranları sayı ve ağırlık bakımından sırasıyla %50,6 ve %56,9 olarak belirlenmiştir. Hedef avın (Parapenaeus longirostris) azalması sayı olarak %23,1, ağırlık bakımından ise %23,2 olarak bulunmuştur. En düşük AIC değerine göre elde edilen derin su pembe karides modelinde ızgaranın seçicilik parametreleri L50 için 13,51 cm ve SR için 4,76 cm'dir. Aynı türün 24 mm ağ gözü açıklığındaki seçicilik parametreleri; L50 = 8,99 cm ve GD = 5,56 cm'dir. Bu sonuçlar, hedef av odaklı balıkçılık uygulamalarında ızgara panel kullanımının sürdürülebilir balıkçılığa fayda sağladığını ve etkili olduğunu göstermiştir.
