Overlap of small-scale fisheries with sea turtle high-use areas is of growing concern, but the extent to which these endangered species interact with fishing gear is rarely known. Structured face-to-face interviews with 22 longline vessel captains were used to make a rapid assessment of sea turtle bycatch by the artisanal longline fleet of Barbados in the eastern Caribbean. Extrapolated estimates suggested that an average of 284 sea turtles yr−1 were caught on 1 896 200 hooks, a bycatch per unit effort of 0.15. Based on extrapolation of the percentage of the observed vessels to the entire fleet, an estimated average of 374 sea turtles yr−1 are caught. The majority of captains (86%) reported leatherback turtles Dermochelys coriacea to be the predominant species. The Barbados longline fleet operates in sea areas through which le atherbacks pass on their way to and from important nesting beaches in Trinidad and Tobago, Grenada, and the Guianas, and in which they reside during the pre-nesting period as well as throughout the nesting season. Although most sea turtles caught as bycatch were released alive, they often remained hooked with trailing lines. The majority of captains expressed their willingness to be trained in safe-handling and release of hooked and entangled turtles, to increase the probability of their survival.

东加勒比手工延绳钓渔业中的棱皮龟兼捕

小规模渔业与海龟高利用区的重叠越来越受到关注,但这些濒危物种与渔具相互作用的程度鲜为人知。通过与 22 名延绳钓船船长的结构化面对面访谈,对加勒比东部巴巴多斯手工延绳钓船队的海龟兼捕情况进行了快速评估。外推估计表明,平均 284 只海龟 yr-1 被 1 896 200 个鱼钩捕获,每单位努力的误捕为 0.15。根据观察到的船只占整个船队的百分比外推,估计平均每年捕获 374 只海龟。大多数船长 (86%) 报告棱皮龟 Dermochelys coriacea 是主要物种。巴巴多斯延绳钓船队在特立尼达和多巴哥、格林纳达和圭亚那重要的筑巢海滩途中经过这些海域,它们在筑巢前和整个筑巢期间都居住在这些海域季节。虽然大多数被兼捕的海龟被活释放,但它们经常被拖绳钩住。大部分船长表示愿意接受钩龟和缠结龟的安全处理和释放培训,以增加其生存的可能性。他们经常被拖尾线迷住。大部分船长表示愿意接受钩龟和缠结龟的安全处理和释放培训,以增加其生存的可能性。他们经常被拖尾线迷住。大部分船长表示愿意接受钩龟和缠结龟的安全处理和释放培训,以增加其生存的可能性。
