Each lunar month from 1994–2023, we counted postlarvae on artificial collectors at two locations in the Florida Keys (USA). We compared various indices of puerulus settlement and commercial landings. Significant correlations between postlarval indices and the sum of August and September commercial landings were identified at one sampling location. Commercial landings in these first two months of the fishing season likely represent a better index because, as the fishing season progresses, fishing effort and landings are influenced more by non-recruitment factors such as tropical disturbances, catch levels, and the price of lobster. The postlarval index with the highest correlation to landings included the months with peak settlement between January and June in the year prior to the fishing season (p &lt; 0.001). The timing of the postlarval index and range of months indicates that it takes between 14- and 20-months post-settlement for a lobster to enter the fishery and that these peak settlement pulses drive landings in the commercial fishery. The correlation between postlarval settlement and fishery landings suggests that the quantity of postlarvae — and not post-settlement processes — is the primary driver of the spiny lobster population in Florida. Results from this study also indicate that postlarval settlement levels have declined over the past 30 years. As a population that relies heavily on postlarval supply from outside of Florida, this highlights the need for future research into the cause of the decline and any potential link to spawning stock biomass, particularly considering declining landings Caribbean-wide.</p></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"279 ","pages":"Article 107137"},"PeriodicalIF":2.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0165783624002017/pdfft?md5=09dc12196dc041a5643c8feee00d55bc&pid=1-s2.0-S0165783624002017-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141930140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Constructing a conceptual model (CM) should be the first step when planning a new stock assessment or updating previous assessments, because it can improve the modelling process by guiding the workflow and “modelling what to model”. CMs should be built by summarizing information about a system while also proposing hypotheses or assumptions about the uncertainties and unknown aspects. Several steps are necessary to build a CM: 1) gather known information about the species and the fisheries that interact with it, 2) state the objectives of the stock assessment, 3) define the spatial scale, 4) define the temporal scale, and 5) outline components and processes of the system (biological, fisheries and observation processes) and what drives them. Initial draft CMs should be based on the best available science and constructed using the fundamental principles of ecology, socioecology, fisheries and other relevant sciences. CMs offer a framework for integrating knowledge across domains, and benefit from an elicitation process. The elicitation process is a set of deliberate activities (e.g., workshops) that allow other experts and relevant parties to contribute with their knowledge to enrich draft CMs. CMs are not static entities but rather dynamic constructs that can identify future research directions and evolve to incorporate new insights and knowledge. Fisheries systems for highly migratory pelagic species in the Pacific Ocean (north Pacific Albacore tuna, eastern Pacific Dorado, and south Pacific Swordfish) are used as examples to illustrate how to develop CMs, and demonstrate improvements to the subsequent assessment models following development of the CMs.</p></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"279 ","pages":"Article 107135"},"PeriodicalIF":2.2,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141930141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fishery at South Georgia accounts for 26 % of the catch of this species in the Southern Ocean in the last 25 years. This study assesses the effects of exploitation and changes in management of the fishery on long-term trends in biological traits of Patagonian toothfish at South Georgia. Our results show variability in the size of fish, but no evidence of a systematic decline during the 25-year period. The mean size of fish was linked to recruitment, with pulses of recruitment associated with a reduction in mean size of the fishery. The years when recruitment was highest were in 2000–2010, with &gt;50 % of toothfish of length classes &lt; 90 cm. Management measures implemented over the last 25 years, including depth restrictions and benthic closed areas, have resulted in a gradual stabilization of the population structure. Catch per unit effort (CPUE) dropped from 1997 to 2010, gradually increased until 2017 and since 2018 has returned to values typical of the mid-2010s. Monthly changes in fish length, depth of capture and CPUE confirm that the spawning peak is in July. Size at maturity has remained stable over the last 25 years, suggesting the fishery has not had a major impact on population size structure. These results illustrate the role of management regulations in limiting the impacts of commercial exploitation on the population structure of a long-lived fish species. Given the bigger-deeper size pattern in Patagonian toothfish, there may be a case for increasing the minimum depth of the fishery (currently 700 m) when strong recruitment pulses are detected.</p></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"279 ","pages":"Article 107122"},"PeriodicalIF":2.2,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0165783624001863/pdfft?md5=dc207e0ae7a4bf03a1f5f19461e1852e&pid=1-s2.0-S0165783624001863-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141930144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we employed the bomb radiocarbon chronometer to test the accuracy of age estimates (n = 3 readers) derived from opaque zone counts in whole otoliths, as well as dorsal spine section translucent zone counts produced with the historical ageing protocol and a new method that requires higher magnification to count translucent zones on the margin of dorsal spine sections. Results indicate historical dorsal spine-derived age estimates underestimate age, with the extent of bias increasing with age. There was no evidence of ageing bias for both whole-otolith opaque zone counts and new protocol dorsal spine translucent zone counts. New dorsal spine protocol ageing was slightly more precise among readers (iAPE = 9.4 %) than otolith ageing (iAPE = 10.1 %) and read times were 2–3x faster for dorsal spine sections than whole otoliths. Validation of the new dorsal spine ageing protocol is a critical step in effective production ageing of gray triggerfish.
