Currently, horseshoe crabs along the U.S. Atlantic coast are harvested as bait for other fisheries and collected for their blood, which is used in a biomedical industry. The Delaware Bay is home to the largest population of horseshoe crabs and is a significant stopover for shorebirds to rebuild energy by consuming horseshoe crab eggs prior to completing their northward migration. To address this interrelationship, the Adaptive Resource Management (ARM) Framework has been used since 2013 to ensure that horseshoe crab harvest within the region takes into account the forage needs of migratory birds. Since its inception, the ARM Framework has used a single trawl survey's swept area-based population estimates of horseshoe crab relative abundance and a theoretical population model developed primarily from literature-derived values.

Smith","doi":"10.1002/mcf2.10240","DOIUrl":"10.1002/mcf2.10240","url":null,"abstract":"<p>In a rapidly changing environment where fires are becoming more frequent and severe, scientists and managers need information and tools to enhance understanding of the numerous ways in which fire can affect fisheries. We used Ostrom's social–ecological systems framework to structure the development and refinement of fuzzy cognitive maps with stakeholders across the Kenai River fishery in Alaska, USA. The process yielded a model characterizing the structure and function of the Kenai River fishery. The model was then used to guide interviews with stakeholders focused on the effects of the 2019 Swan Lake Fire. We identified seven direct pathways through which fire can affect the social and ecological components of a coastal fishery. We also used the model to guide a targeted literature review to further explore how fire can affect the components of the Kenai River fishery. This synthesis of information allowed us to develop a more complete understanding of the impacts of fire on the fishery—an understanding informed by input from local stakeholders (via our interviews) and relevant scientific and management literature (via our literature review). Lastly, we used the model to assess the fishery's vulnerability to fire. We discuss how early run Chinook Salmon <i>Oncorhynchus tshawytscha</i> constitute a highly vulnerable component of the system and have the greatest potential to impact the fishery as a whole through a chain of negative social and ecological interactions. This final step illustrates how the model can be used to assess the vulnerability of system components to specific threats. The model of the Kenai River fishery provides an empirically grounded and easily understood visual representation of the complex dynamics affecting coastal fisheries. As such, it can be used to structure discussions among managers and stakeholders, organize our understanding of how fire affects fisheries, and assess vulnerabilities to endogenous and exogenous stressors.</p>","PeriodicalId":51257,"journal":{"name":"Marine and Coastal Fisheries","volume":"15 3","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mcf2.10240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44600907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For Southern Flounder <i>Paralichthys lethostigma</i>, recent otolith chemistry studies have revealed a diversity of residency patterns across salinity gradients. However, the contribution of recruits with specific residency patterns to fisheries is poorly understood. The objectives of this study were to (1) use otolith chemistry from fishery-independent and fishery-dependent collections in Mobile Bay, Alabama, to classify lifetime residency patterns (i.e., freshwater, transient, estuarine) in Southern Flounder collected across a large estuarine salinity gradient (0–30 psu); (2) to test if Southern Flounder exhibited resident or migratory behavior by determining if lifetime residency patterns in fishery-independent samples matched expected salinity patterns in the region of collection after accounting for annual variation in river discharge; and (3) to examine which residency patterns contributed to the commercial and recreational Southern Flounder fisheries in nearby coastal waters. Age-0 residency patterns in fishery-independent samples were strongly correlated with region of collection and annual river discharge, suggesting that the majority of Southern Flounder had resided in the same region in which they spent their age-0 growth phase. Southern Flounder with a combination of freshwater and estuarine salinity signals and classified as “transient” did not appear to have conducted large-scale movements across salinity gradients, but instead resided in regions of the estuary experiencing seasonal fluctuations in salinity. The majority (57%) of commercially and recreationally harvested Southern Flounder were transients, while a minority (39%) were estuarine residents and lifetime freshwater residents (4%) were rarely harvested. Results from this study suggest that Southern Flounder settle in and remain in the certain habitats during the estuarine residency phase. Given the lack of movement across habitats, future efforts to understand how habitat-specific conditions (e.g., abiotic, biotic, fishing exploitation) affect vital rates seems warranted for a species currently experiencing population declines.</p>","PeriodicalId":51257,"journal":{"name":"Marine and Coastal Fisheries","volume":"15 3","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mcf2.10243","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50137151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
