Northern shortfin squid (Illex illecebrosus) have presented a challenge for US fishery management because of their life history traits and broad population distribution. They are characterized by a short semelparous lifespan and high interannual variability in recruitment. Much of the stock resides outside of the boundaries of existing US fisheries surveys and US fishing effort. Based on the annual migration pattern and broad geographic distribution of shortfin squid, it is believed that the US squid fishery in the Mid-Atlantic has not had a substantial impact on the stock; however, recent catches are viewed as tightly constrained by quotas. To better estimate the potential impact of fishing on the resource, we worked with industry representatives, scientists, and managers to estimate the availability of the northern shortfin squid stock on the US continental shelf to the US fishery. Taking a novel analytical approach, we combine a model-based estimate of the area occupied by northern shortfin squid with the empirical US commercial shortfin squid fishery footprint to produce estimates of the area of overlap. Because our method overestimates the fishery footprint and underestimates the full distribution of the stock, we suggest that our estimates of the overlap between the area occupied by the squid and the fishery footprint is a way to develop a conservative estimate of the potential fishery impact on the stock. Our findings suggest a limited degree of overlap between the US fishery and the modeled area occupied by the squid on the US continental shelf, with a range of 1.4–36.3%. The work demonstrates the value of using high-resolution, spatially explicit catch and effort data in a species distribution model to inform management of short-lived and broadly distributed species, such as the northern shortfin squid.

北方脆片鱿鱼伊列克斯）因其生活史特征和广泛的人口分布而对美国渔业管理提出了挑战。它们的特征是较短的茎突寿命和较高的年际变化。许多种群位于美国现有渔业调查和美国渔业活动范围之外。根据短鳍鱿鱼的年迁移模式和广泛的地理分布，可以认为，大西洋中部的美国鱿鱼捕捞对种群没有产生实质性影响。但是，最近的捕捞量被配额严格限制。为了更好地估算捕捞对资源的潜在影响，我们与行业代表，科学家和管理人员一起估算了美国大陆架上北方短鳍鱿鱼种群对美国渔业的可用性。我们采用一种新颖的分析方法，将基于模型的北方短鳍鱿鱼占据面积的估计值与美国的商业性短鳍鱿鱼渔业足迹的经验值相结合，得出重叠面积的估计值。因为我们的方法高估了渔业足迹，而低估了种群的全部分布，所以我们建议，我们对鱿鱼所占面积和渔业足迹之间重叠部分的估算是一种保守估计潜在渔业对渔业影响的方法。股票。我们的发现表明，美国渔业与鱿鱼在美国大陆架上的建模区域之间的重叠程度有限，范围为1.4–36.3％。该作品展示了使用高分辨率的价值，
