Objectives: Safety at sea is an often overlooked aspect of well-being that fisheries management actions can affect, even when management actions are not intended to affect safety. Catch shares management has been associated with longer fishing seasons and a decline in the intensity of competition among fishers. This study assesses changes in exposure of Alaska’s commercial crab fisheries to relatively high-risk weather conditions after rationalization, or catch shares management, was implemented.

Methods: We compare the rates of fishing in high-wind conditions in the Bristol Bay red king and the Bering Sea snow/tanner crab fisheries pre- and post-rationalization. We also compare results to a portion of the crab fishery that did not undergo the same change in management.

Results: The rate of high wind fishing in the snow/tanner crab fishery fell post-rationalization, but increased in the red king crab fishery.

Conclusion: When the red king and snow/tanner crab fisheries are considered together, rationalization led to longer seasons and improved flexibility to choose when to fish according to weather conditions. The snow crab fishery experienced a marked decline in higher-risk fishing after rationalization. Results are contrary to expectations for the king crab fisherybecause the flexibility in trip timing provided by the program produced a shift in their season toward winter months when average wind speeds are higher.

目标：海上安全是渔业管理行动可能会影响的福祉的一个经常被忽视的方面，即使管理行动并非旨在影响安全。渔获量管理与更长的捕鱼季节和渔民之间竞争强度的下降有关。这项研究评估了实施合理化或捕捞份额管理后，阿拉斯加商业蟹类渔业在相对高风险的天气条件下的暴露变化。

方法：我们比较了在合理配水前后，在布里斯托尔湾红王和白令海雪/鞣革蟹渔业中在强风条件下的捕捞率。我们还将结果与部分未进行相同管理变更的蟹类渔业进行了比较。

结果：合理化后，雪/制革蟹渔业中的高风速捕鱼率下降，而红帝王蟹渔业中的高风速捕鱼率增加。

结论：当一起考虑红色国王和雪/鞣制蟹的渔业时，合理化导致更长的季节并提高了根据天气条件选择捕鱼时间的灵活性。合理化后，雪蟹渔业的高风险捕鱼活动明显减少。结果与对帝王蟹捕捞的期望相反，因为该计划提供的出行时间安排的灵活性使他们的季节转向了冬季，冬季平均风速更高。
