摘要：
The aim of this study, carried out during 2001 and 2002, was to assess the interaction between turtles and bottom trawls in the Gulf of Gabes, which is considered an important wintering and foraging area for the loggerhead in the Mediterranean. Catch rates are estimated at 0.01142 +/- 0.00292 turtles/haul with a total catch of 5458 +/- 1652 turtles/year. However, the total mortality is low (182 +/- 55/year), probably due to the short haul duration. Captures occur mainly during winter, spring and summer, with significantly higher rates at depths of less than 50 m.
