Structure can even occur within populations, because of the lack of random mating (panmixia) between individuals, which is often a consequence of stocking with exogenous fish. In this study, we aimed to evaluate fragmentation in brown trout populations of the Pedroso River (Duero basin) to assess the effect of artificial barriers in this system. Our results indicated a significant isolation of populations in the headwaters, which translates into a low genetic diversity, a small effective population size and a high rate of inbreeding. We also found an unexpected substructure in one of the downstream localities (PED-02), where the youngest individuals were genetically different. Genetic analysis confirmed that these rare individuals come from a hatchery native stock used to stocking Pedroso River. Because this stock was originated with individuals from Pedroso itself, we must consider that a strong founder effect took place. Over the years, genetic drift accentuated the genetic differentiation of this stock from the original population. From our results, we made some recommendation for the management and conservation of brown trout in the Pedroso River, based on the removal of the main barriers that isolate the upstream populations, after stopping the restocking carried out with ‘native invaders’ fish from the local hatchery.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interdisciplinary study was conducted to assess the population genetic structuring of the species with the help of conventional morphometric, image-based truss network and genomic data of a nonprotein encoding mitochondrial DNA region (partial D-loop −494 bp) (<i>n</i> = 106). Fishes were collected from five rivers of the Western Ghats, namely, Kali, Sharavathi and Chalakudy (west-flowing) and Ghod and Tungabhadra (east-flowing) (<i>n</i> = 294). Multivariate analysis of body measurements and truss distances revealed very weak separation among populations. The D-loop sequence analysis showed that genetically distinct populations of fishes inhabit the studied rivers. Principal component analysis (PCA) and linear discriminant analysis (LDA) could not completely distinguish morphologically distinct populations. D-loop sequence analysis indicated 13 haplotypes with low nucleotide diversity and 15 polymorphic sites, with location-specific haplotypes. An overall haplotype diversity of 0.80 and nucleotide diversity of 0.00849 were found. The haplotype network and maximum likelihood phylogenetic tree showed three clusters with two most probable ancestors. Analysis of molecular variance (AMOVA) showed a high value (0.898) of the fixation index (F_ST) among the populations (<i>p</i> &gt; 0.05). Neutrality test and mismatch distribution results indicated that the populations are currently subjected to selection. Application of an integrated approach to characterise the populations of <i>H. curmuca</i> in the wild supports the hypothesis of geographical barriers as major drivers of population genetic differentiation. Different riverine environments have not selected for morphological differences during the evolutionary process in the recent past and showed weak separation of populations.

A lack of comprehensive data on threatened elasmobranchs (sharks and rays), including guitarfish, hinders evidence-based management. This study evaluated the status of guitarfish, focusing on the effects of artisanal fishing and the socioeconomic circumstances of fishers impacting catch and perceived catch trends. The impacts were assessed spatially and temporally in coastal Bangladesh. Interviews were conducted with 150 artisanal fishers in primary fish landing locations and fishing communities. The analysis showed a notable decrease in the perceived catch of various guitarfish species. Catch decreased significantly for <i>Glaucostegus granulatus</i>, sharpnose guitarfish, and <i>Rhina ancylostoma</i>, bowmouth guitarfish in the past decade. The decrease was linked to overfishing, illegal/harmful fishing techniques and injuries from fishing equipment. Fishing-related (soak time, gear, depth at fishing and vessel length) and socioeconomic drivers (income and debt levels) were found to impact guitarfish catch levels. Socioeconomic factors complicate the situation because these factors influence fishers' fishing habits, perspectives and decision-making. Guitarfish were caught both as a target and incidentally. Most captures occurred in the southcentral region of Bangladesh. Four hotspots of guitarfish catches were identified based on the fishers' knowledge. The critical habitats in the Ganges-Brahmaputra-Meghna (GBM) delta mouth area are vital habitats for guitarfish, highlighting the need to protect these ecosystems using spatial management tools. To tackle the complex issues of guitarfish conservation, the local fishing communities need a holistic strategy combining biological knowledge, socioeconomic factors and specific codesigned initiatives. Although fishers may lack formal education, there is a distinct potential for specialized and bilateral conservation education programmes to empower fishing communities and promote sustainable practices. Conservation measures should focus on mixed methods, such as community engagement, enhanced socioeconomic circumstances and efficient spatial and fishing technique management.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macrobenthos, an important component of aquatic ecosystems, with limited mobility and sensitivity to environmental changes, commonly serve as indicators of aquatic ecosystem health. This study, conducted in the summer and autumn of 2022 in Sishili Bay (SB) and the Changdao Archipelago (CA), Yantai, China, aimed to evaluate the effects of artificial reefs on macrobenthic community structure using functional trait analysis. The nonmetric multidimensional scaling (nMDS) analysis based on species abundance and occurrence frequency did not reveal any clear separation between areas inside and outside the artificial reefs. However, the construction of artificial reefs increased the species number of macrobenthos, especially the Mollusca species. Feeding type, a key functional trait, distinguished areas inside and outside artificial reefs, with significant spatial and temporal variations. The key species driving differences between reef and nonreef areas include the carnivorous <i>Lumbrineris longifolia</i> and <i>Glycinde bonhourei</i> and the omnivorous <i>Eriopisella sechellensis</i> and <i>Sigambra bassi</i>, which were pivotal in the observed variations in relative abundance. Functional richness (FRic) and species richness (<i>S</i>) showed consistent patterns of variation, both contributing to improving the community stability in summer. However, in autumn, community stability was reduced by the extraordinary dominance of a single species. Multiple environmental factors rather than a single one significantly influenced species distribution and diversity, reflecting the complex interplay of reefs and seasonal dynamics. This study used functional trait analysis to assess the impact of artificial reefs on macrobenthic community structure, offering a more effective measure than species-level assessments.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
