摘要: Summary Scientific studies have been conducted on size selectivity of trawls with grids in the Mediterranean; however, none has focused species selectivity. The aim present study was to analyze value sorting 20 mm bar spacing for separation, a demersal trawl fishery mainly targeting deep water rose shrimp (Parapenaeus longirostris) Eastern Mediterranean. Fishing trials were carried out 17–24 August 2008 onboard commercial trawler ‘Hapuloglu’, using modified bottom net. separation rate silver scabbard fish (Lepidopus caudatus) highest among all 98% by weight and 97% number 44 mm diamond (44D) 40 mm square mesh (40S) codends, respectively. exclusion European hake (Merluccius merluccius) grid shows differences between 85 93%, 64 83% codends 44D 40S, Excluding ratio greater forkbeard (Phycis blennoides), angler (Lophius piscatorius) broadtail short fin squid (Illex coindetii) varied 93 weight, 81 86% both codends. Losses legal sized determined as 23 25% results obtained demonstrate that substantial can be achieved this Mediterranean fishery. However, further developments should explored; purpose behaviour studied relation design where consequences changes gear technology need considered.
