: 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.: 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.: The rate of high wind fishing in the snow/tanner crab fishery fell post-rationalization, but increased in the red king crab fishery.: 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.
海上安全是福祉的一个常被忽视的方面,渔业管理行动即使不是为了影响安全,也可能会影响到安全。捕捞份额管理与捕鱼季节的延长以及渔民之间竞争强度的下降有关。本研究评估了阿拉斯加商业蟹类渔业在合理化(即捕捞份额管理)实施后,暴露于相对高风险天气条件下的变化情况。我们比较了布里斯托尔湾红帝王蟹和白令海雪蟹/珍宝蟹渔业在合理化前后在大风天气下捕鱼的比率。我们还将结果与未经历相同管理变革的一部分蟹类渔业进行了比较。在合理化之后,雪蟹渔业中在大风天气下捕鱼的比率下降,但红帝王蟹渔业中则上升。当将红帝王蟹和雪蟹渔业一起考虑时,合理化导致了更长的季节和根据天气条件选择捕鱼时间的灵活性提高。在合理化之后,雪蟹渔业中高风险捕捞的比例显著下降。结果与帝王蟹渔业的预期相反,因为该计划提供的旅行时间灵活性导致其季节向平均风速更高的冬季转移。
