The purpose of this study was to investigate the survival rate of red mullet (Mullus barbatus L., 1758) after escaping from a commercial bottom-trawl codend in the Bay of lzmir, east coast of the Aegean Sea. The experiments were conducted in September 2001. A traditional bottom trawl with a 40 mm codend was towed for 15 min. A cover over the codend was used to catch the escaping fish. Then the cover was detached front the codend and deployed at the observation site by divers. One control and three experimental hauls were carried out; the cod-line was left untied in the case of the control. Divers observed the cages three times per day over a 6-day period to remove dead fish and feed the survivors. On average, 93% of the red mullet in the three test cages survived during the observation period. (C) 2004 Elsevier B.V. All rights reserved.
