摘要

弃物死亡率可能是种群评估和渔业管理措施的潜在重大不确定性来源。虽然人们认为果胶科在捕获和处理过程中很强健,但了解特定物种的丢弃死亡率对于确定种群动态特征和制定监管措施以实现管理目标至关重要。在商业条件下,通过对工业船只的滞留研究,对美国疏浚渔业的麦哲伦扇贝丢弃死亡率进行了经验估计。通过扇贝活力的综合指数对16,000多只海扇贝进行了评估,该指数包括显性创伤(外壳损伤)和对刺激的反应的半定性测量。结果表明,扇贝总弃置死亡率为21%,与目前种群评估的假设值一致。生存混合模型支持物理创伤的简单度量作为死亡率的有效预测指标的效用。暴露时间也被确定为一个正相关因素,在描述丢弃死亡过程中很重要。实验结果的应用突出表明,需要考虑渔业的一些操作特征,以减少潜在的弃置死亡率。

Discard Mortality of Sea Scallops Placopecten magellanicus Following Capture and Handling in the U.S. Dredge Fishery

Discard mortality can represent a potentially significant source of uncertainty for both stock assessments and fishery management measures. While the family Pectinidae is considered to be robust to the capture and handling process, understanding species-specific discard mortality rates is critical to characterize both population dynamics and to develop regulatory measures to meet management objectives. The discard mortality rate for the U.S. dredge fishery of sea scallop Placopecten magellanicus was estimated empirically via a retention study aboard industry vessels under commercial conditions. Over 16,000 sea scallops were assessed via a composite index of scallop vitality that consisted of semiqualitative measures of both overt trauma (shell damage) and response to stimuli. Results indicate that overall sea scallop discard mortality was 21% and consistent with the values currently assumed in the stock assessment. Survival mixture models support the utility of a simple metric of physical trauma as an effective predictor of mortality. Exposure time was also identified as a positively correlated factor that was important in describing the discard mortality process. Application of experimental results highlight the need to consider some operational characteristics of the fishery to reduce potential discard mortality.

期刊介绍: Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science publishes original and innovative research that synthesizes information on biological organization across spatial and temporal scales to promote ecologically sound fisheries science and management. This open-access, online journal published by the American Fisheries Society provides an international venue for studies of marine, coastal, and estuarine fisheries, with emphasis on species'' performance and responses to perturbations in their environment, and promotes the development of ecosystem-based fisheries science and management.
