This research addressed these aspects by investigating Clupeiformes ichthyoplankton across four main ecological regions of Vietnam (North, Central, Southeast, and Southwest). Ichthyoplankton samples, including eggs and larvae, were collected from surface and vertical layers during both main and secondary spawning seasons. An integrated approach, combining morphological characteristics and COI mtDNA gene, was employed to identify 17 clupeiforms species and link their developmental stages. This study successfully connected the egg, larval, and early juvenile stages with adult conspecifics for four key species: <em>Anodontostoma chacunda</em>, <em>Hilsa kelee</em>, <em>Escualosa thoracata</em>, and <em>Stolephorus insularis</em>. Phylogenetic analysis of the 17 Clupeiformes species using COI revealed a clear divergence between the two main families (Dorosomatidae, and Engraulidae). To further resolve these relationships, a mitogenome-based phylogenetic analysis was performed, which critically confirmed a paraphyly within the genus <em>Sardinella</em>. For instance, <em>Sardinella fijiensis</em> did not cluster with other <em>Sardinella</em> species but appeared as a sister group to <em>Hilsa kelee</em>. Significant intraspecific variation, both morphological and genetic, was also observed across the different geographical regions and developmental stages examined. By providing detailed insights into early life histories, resolving some taxonomic uncertainties with mitogenome data, and highlighting geographically and ontogenetically structured intraspecific variation, this study offers critical information for refining management units, identifying essential fish habitats, and developing effective conservation strategies for these vital fish resources in Vietnam.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"295 ","pages":"Article 107674"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147404219","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}

Despite a peak catch of 130.8 thousand tons in 2014, annual catches have steadily declined since 2015, primarily due to overfishing, hitting a historic low of 17.7 thousand tons in 2018. Although recent management strategies, including area closures, have fostered a partial recovery, production levels remain below pre-decline levels. To inform sustainable fisheries management, this study evaluates the genetic diversity and population dynamics of short mackerel in the Gulf of Thailand over a decade. We analyzed 256 recent samples from five spawning grounds --Trat, Samut Songkram, Prachuap Khiri Khan, Surat Thani and Pattani-- in the Gulf of Thailand between 2022 and 2024, comparing them with preceding samples from 2011 to 2018 using eleven microsatellite loci. Our results revealed moderate genetic diversity across populations and showed relatively stable diversity indices over time. Notably, immigration rates between populations have significantly increased in the past decade, suggesting enhanced gene flow. These findings highlight the effectiveness of area closures in maintaining genetic stability and promoting short mackerel population resilience. Stable genetic diversity and increased gene flow among populations underscore the importance of continued genetic monitoring and adaptive management to sustain short mackerel resources in the Gulf of Thailand. By leveraging genetic insights, fisheries management can further optimize strategies to ensure the recovery and long-term sustainability of the short mackerel populations.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"295 ","pages":"Article 107676"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147404220","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}

This study asked whether incorporating NTMR data improves the accuracy of annual abundance forecasts over eight years. We compared the predictive performance of first-order autoregressive models that were trained on abundance data from either NTMR sites, fished sites, or a mix of both site types. Each model was then tested by predicting to sites it was not trained on (‘transferred’). We tested the forecasts for both fished and unfished species with 23 years of time-series abundance data from the Maria Island (Tasmania) NTMR and nearby control sites. We found a general decrease in the performance of fished and NTMR models when forecasts were transferred to the opposite site type. Model transferability was species-specific, with the NTMR model reducing forecast errors by approximately 10 % at fished sites for one sustainably fished species. In contrast, for other species, the fished model reduced forecast errors by approximately 4 % and 56 % at NTMR sites. Additionally, we found that models trained on a mix of site types consistently underperformed. These findings highlight the importance of accounting for site- and species-specific dynamics.

A total of 679 individuals were collected between 2022 and 2024, and their otolith elemental composition was analysed using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS).

A sensitivity analysis confirmed the robustness of the results and indicated a negligible effect of individual length. Although some interannual variability was detected over the three-year period, spatial differences consistently exceeded temporal variation. Spatial differences in elemental signatures likely reflect underlying oceanographic drivers, such as water temperature and salinity, which influence otolith-edge chemistry.

This study developed a novel single nucleotide polymorphism (SNP) marker panel for Sydney Cockle, and applied this to evaluate population structure across south-eastern Australia and inform future AAE. Sample collection targeted locations where the species had previously been found and spanned &gt; 1100 km of coastline, but sampling efforts also revealed the potential extirpation of Sydney Cockle across a large swath of coastline. Analyses did not provide evidence for genetic structure across the region investigated. Overall <em>F</em>_ST was low (0.004), and the pairwise comparisons suggested only minor genetic distances among locations (<em>F</em>_ST ≤ 0.037). Furthermore, discriminant analysis and a likelihood-based clustering analysis did not indicate that any population subdivision was present. The SNP data revealed little evidence for any intra-estuarine structure or discontinuous stock structure across the sampled area, and there was no relationship between genetic distance and geographic distance. Similar results were obtained when stringent filters used to remove any bias in the data were removed. The south-eastern Australian estuaries supporting Sydney Cockle can be considered as connected units within minimal genetic differentiation, however the management of persistent local populations may require considerations broader than genetic structure. The genetic markers developed, and associated population analysis, provide a solid foundation for genetic resource management of any future AAE efforts for the species.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"295 ","pages":"Article 107675"},"PeriodicalIF":2.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147404222","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}

Using data from 12,804 fishing trips recorded in 2009 across ten traditional villages, we employed multiple correspondence analysis to identify 96 tactics—combinations of gear type, target species, and fishing location—and how they are integrated into fishing strategies. Despite operating within a shared environment and having access to similar fishing grounds, each village adopted a unique set of tactics and developed distinct strategies. Use of space was segregated, with each village concentrating its activity in the closest spatial sector. Temporally, all villages combined a \"backdrop\" of frequent, year-round tactics with exclusive, more rewarding, seasonal tactics. Economic factors played an important role in shaping these strategies. Fishers achieved a <em>portfolio effect</em> by combining a generalist logic encompassing many high-frequency, lower-revenue, lower-cost, and lower-risk practices with a specialist logic of fewer, higher-cost, higher-reward practices. These results support the hypothesis that fishing strategies segregated by groups of fishermen coexist in a complex, diverse socio-ecological system.

The reference points used in fisheries harvest control rules (HCRs) are often related to unfished biomass conditions (<em>B</em>₀) and are calculated assuming that biological parameters and their associated functional forms (e.g., unfished recruitment (<em>R</em>₀), natural mortality (<em>M</em>), growth) are stationary (‘static <em>B</em>₀’). However, there is increasing evidence that the assumption of stationarity is untenable in the face of environmental change. Biomass dynamics models are a common assessment method to assess stock status and to apply HCRs in data-moderate situations. We extend the constrained biomass dynamics model (‘dynamic tier 4’) used in Australia’s Southern and Eastern Scalefish and Shark Fishery to define stock status and reference points based on ‘dynamic <em>B</em>₀’ (the biomass to be expected in the absence of fishing). We then use management strategy evaluation (MSE) to contrast the performances of HCRs when assessments are based on the ‘dynamic tier 4’ management strategy as well as on a management strategy based on an age-structured method of stock assessment (tier 1, Stock Synthesis) when climate-induced change leads to declines in expected recruitment or increases in natural mortality and when reference points are based on static or dynamic <em>B</em>₀. The results are summarized using performance measures based on static and dynamic <em>B</em>₀, as well as absolute stock size, total catches and catch variability.
