摘要

海龟极易受到商业捕捞的负面影响。2007年10月，马里兰州自然资源部召集了一个工作组，讨论马里兰州的鳄龟(Chelydra serpentina)渔业，并提出了维持可持续渔业所需的建议。我们收集了种群结构和当地采集者在田间使用的采集技术的信息。法定最小尺寸限制从2008年的9.5英寸(24.1厘米)增加到2009年的11英寸(27.9厘米)，导致更多的雌性受到保护而不被捕捞，但单位努力的渔获量却显著减少，迫使捕捞者增加捕捞努力以维持渔获量。

Field Data and Stakeholders: Regulating the Commercial Harvest of Snapping Turtles in Maryland

Abstract Turtles are highly susceptible to the negative effects of commercial harvesting. In October 2007, the Maryland Department of Natural Resources convened a Working Group to discuss the snapping turtle (Chelydra serpentina) fishery in Maryland and to make recommendations considered necessary to maintain a sustainable fishery. We collected information on population structure and the collecting techniques used by local harvesters in the field. An increase in the minimum legal size limit from 9.5 inches (24.1 cm) in 2008 to 11 inches (27.9 cm) in 2009 resulted in more females being protected from harvesting yet significantly decreased catch per unit effort, forcing harvesters to increase collecting effort to maintain catch levels.

期刊介绍： Chelonian Conservation and Biology is a biannual peer-reviewed journal of cosmopolitan and broad-based coverage of all aspects of conservation and biology of all chelonians, including freshwater turtles, marine turtles, and tortoises. Manuscripts may cover any aspects of turtle and tortoise research, with a preference for conservation or biology. Manuscripts dealing with conservation biology, systematic relationships, chelonian diversity, geographic distribution, natural history, ecology, reproduction, morphology and natural variation, population status, husbandry, community conservation initiatives, and human exploitation or conservation management issues are of special interest.
