This study of the commercially and recreationally important berycid <em>Centroberyx gerrardi</em> in southern Australia explored implications, for growth estimation, of selectivity and fishing mortality effects across three regions in Western Australia. Using length-at-age data derived from commercial line catches, taken from a large depth range and comprising a wide age range (5–84 years), traditional von Bertalanffy growth models indicated regional differences in growth. These estimated regional differences became reduced when von Bertalanffy growth models were fitted using informative priors to constrain some growth parameters to feasible values. In contrast, a length and age-based catch curve model (LACC) that simultaneously estimates growth, selectivity and fishing mortality indicated no regional growth differences. A simulation study confirmed that, among the three alternative growth models, the LACC is most reliable for estimating growth of <em>C. gerrardi</em> when data for small and young fish are limited. The lengths at which <em>C. gerrardi</em> become selected by commercial line fishing differed among regions, potentially reflecting a size-related, westward movement of fish along the south coast to important spawning areas.

This suggests the necessity of a multispecies MSY (MMSY). Although there are several definitions of MMSY, there is no agreed best definition. At least two approaches have been suggested, firstly a community maximum yield, either with or without integrated risk measures designed to prevent stock-depletion, and secondly, defining MMSY in terms of a set of simultaneous single-species MSYs. Here we adopt the second interpretation which allows for the implementation of MMSY without requiring new concepts when combined with multispecies PA to safeguard stock structure. We extend single-species definitions of MSY and PA to give two potential definitions of precautionary MMSY. In the first we constrain the search for MMSY to fishing mortalities that follow the multispecies PA and in the second we find the closest fishing mortality that follows the multispecies PA to the unconstrained MMSY. We demonstrate these definitions using a case study of 9 stocks in the North Sea and compare them with single-species and non-precautionary equivalents.

Despite sardines’ ecological and economic importance, the variability that governs population changes remains poorly understood. Understanding the influence of oceanography on the life history, migration, and population dynamics of sardines is important for fishery management. Over the history of the California Current sardine fishery, numerous studies have attempted to explain why the US and Mexican portions of the sardine biomass off the West Coast should be divided into Northern (Cold - NSP) and Southern (Temperate - SSP) subpopulations. Since 2015, a habitat model including a Sea Surface Temperature (SST) threshold has been used to delineate subpopulations. The assessment and management of the NSP is conducted by the US (using an SST threshold of 16.7° C), while that of the SSP has been conducted by Mexico (using a threshold of 17 °C). Meantime, new population genetics and stock structure studies have found that the reproductive ecology of Pacific sardine reflects a single, panmictic population spread over a wide geographic range and influenced by environmental forcing, suggesting that assumptions regarding the two-subpopulation hypothesis be reconsidered, along with the influence of oceanography on sardine population dynamics. The implications of a single sardine population are significant, as this could result in a review of current US fishery management policies and reference points used to set the annual fishing quotas. In this paper we discuss the importance of the California Current’s influence on the population dynamics of sardine, current fishery management, and management implications.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"293 ","pages":"Article 107643"},"PeriodicalIF":2.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884473","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}

It is therefore essential to both identify the distinct biological units and adjust fishing pressure accordingly. In the northern Baltic Sea, the European whitefish (<em>Coregonus lavaretus</em>) has two ecotypes, anadromous and sea-spawning, harvested primarily with gillnets. The former is endangered due to river connectivity issues and fishing pressure, while the latter is faring better. However, the key elements of effective management, accurate stock component identification and stock-component-specific fishing pressure adjustment, have not been assessed in this mixed-stock fishery. To address this knowledge gap, we compared ecotype identification methods and examined how fishing depth, season, and gillnet mesh size influence the whitefish catch composition. First, we assessed how well the ecotypes could be identified using phenotypic traits (gill rakers and growth) and genetic data (SNP genotyping). While both approaches were useful, many individuals exhibited intermediate characteristics and were not reliably identified, with phenotypic and genetic identification approaches agreeing only moderately. The prevalence of individuals with intermediate traits may reflect past stocking practices, habitat degradation, or inherently inconsistent homing behaviour. Nevertheless, we caught a higher share of sea-spawner-like individuals from deeper waters, earlier in the season, and with gillnets of smaller mesh size. The fact that it was possible to markedly affect the catch composition suggests that spatial and temporal fishing regulations have potential in the management of whitefish mixed-stock fisheries.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"293 ","pages":"Article 107648"},"PeriodicalIF":2.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925289","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}
