The present study had two objectives; the first was to use the natural carbon and nitrogen stable isotope values of wild and farmed totoaba as biomarkers to identify their origin. In the second part of the study, a group of juvenile totoabas was maintained under controlled feeding conditions to explore their rates of isotopic change and estimate the time required for the dietary isotopic values to be transferred into muscle tissue. Results from the feeding experiment indicated that muscle tissue of fish reached an isotopic equilibrium with the offered diet after 28 days for carbon and 43 days for nitrogen. Muscle samples collected from wild and farmed totoaba were analysed and data revealed that the isotopic values (carbon and nitrogen) were significantly different between both groups of organisms. A discriminant analysis using dual isotopic measurements showed a significant separation of classes, indicating that the isotopic values measured at natural abundance levels, can be effectively applied as biomarkers to support the traceability processes of farmed totoaba.

Many populations are in decline, especially the anadromous ecotype towards the southern edge of their range. Evidence-based management is dependent on reliable assessment methods to characterise underperforming populations and identify mitigation actions. Assessment methods based on juvenile data are useful for trout given the species' plasticity. These typically involve comparisons between observed and expected juvenile densities, which vary geographically and with habitat quality. These estimates are mostly obtained through wading electrofishing and field-based habitat surveys. Although some national and regional trout assessment methods have been developed, efforts to develop range-wide evaluations have been constrained by a lack of common protocols. This paper summarises the national methods used to characterise juvenile trout and associated habitat based on information compiled by national representatives of the ICES WGTRUTTA. It then considers opportunities for harmonising data with the aim of developing a range-wide assessment. Survey methods varied substantially within and between countries but showed no clear spatial patterns of coherence. Development of a single set of survey and data collection methods appears highly unlikely. A more pragmatic approach could involve harmonising existing data to make them broadly comparable. This could involve selective use of fish survey data, integration of range-wide macro-scale spatial and habitat data obtained from spatial datasets and use of appropriate modelling frameworks. We also emphasise the critical importance of population data from index rivers to validate and scale juvenile assessments and to compare sampling methods.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431617","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}

These results show an antitropical distribution for the species, which may be a consequence of the climatic instability of Central America during the Pliocene. Additionally, we infer that the divergence of the SCP populations from those of the GC coincided closely with the formation of the Baja California Peninsula, without current migration through the southern end of the peninsula. Finally, we detected a signal of population expansion and substructure within the GC, probably promoted by environmental heterogeneity in this area.

These nest preferentially on the beaches where they were born and may nest more than once during each nesting season, with a variable number of nests per female. Several factors can lead to variations in reproductive output. This study estimated the clutch frequency and internesting period of the threatened subpopulation of the loggerhead turtle (<i>Caretta caretta</i>) from the island of Boa Vista, Cabo Verde. This archipelago hosts the second-largest (or perhaps largest) population of <i>C. caretta</i> globally, with Boa Vista being the most important nesting island. Female distinctions were made on their previous experience (neophytes and remigrants) and their body size. Data were collected between 2013 and 2020 through marking and recapture, on João Barrosa beach, in the Reserva Natural das Tartarugas. In years with more females nesting on beaches, a smaller percentage of nests are studied because of the difficulty in reporting them all. As such, only the first 25% of the nests were analysed. Minimum clutch frequency ranged between 3.8 and 4.1. Remigrants had a larger body size and higher clutch frequency than neophytes, without differences in the internesting period. This study also showed differences between neophyte and remigrant females, specifically only in their measured clutch frequency. However, neophytes likely switch between nesting grounds more often, evading monitoring, and highlighting their potential to move to other islands or to breed out of the main season. These findings enhance our understanding of reproductive strategies, enabling the application of distinct conservation strategies tailored to each group. Satellite telemetry could address study limitations regarding clutch frequency values and provide a better understanding of nesting patterns and the impact of environmental factors on reproduction. This could improve conservation strategies by identifying critical habitats and guiding targeted protective measures, supporting population recovery.</p>\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431569","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}

This study aims to reveal the relationship between the river estuarine fish fauna and the environmental factors including anthropogenic impacts as the basic knowledge necessary for the conservation and restoration. The Bōsō Peninsula (Japan) was selected as the study area. We identified the environmental factors that affected the fish species diversity and determined the factors that affected the habitat structure in the river, while focusing on anthropogenic impacts and topographical conditions. The fish species that occur in river estuaries are strongly influenced by habitat-scale factors, such as flow velocity and water depth, along with watershed-scale factors (such as wave exposure and direct fetch). In addition, the width–depth ratio, which indicates the degree of river channelization, was an important factor that controlled the habitat structure of the fish in the estuary. The results suggest the need for developing restoration plans based on the predictions of the potential physical environment, while considering the predictions for the occurrence of different fish species in the target area.

To assess the potential benefits of such designations, it is necessary to understand the nature of the threats that have been excluded. Here, we summarise over 25 years of historical catch and effort data for a pelagic longline fishery that formerly operated within the recently designated LSMPA surrounding Ascension Island (UK), using data compiled from logbooks and observer programmes. Licenced fishing by foreign vessels (primarily flagged to Taiwan and Japan) operated intermittently in the Ascension Island exclusive economic zone (EEZ) between 1988 and 2016, with catch peaking at over 5000 t year<sup>−1</sup> in the early 1990s. Bigeye tuna (<i>Thunnus obesus</i>) was the dominant species targeted (76% of total catch weight) whilst oceanic sharks (e.g. blue shark <i>Prionace glauca</i>) and other predatory pelagic finfish (e.g. longnose lancetfish <i>Alepisaurus ferox</i>) appear to have presented a sizable bycatch risk, accounting for 37% of total individuals caught in local observer data. The fishery displayed strong seasonality, with two thirds of activity occurring between December and March and was consistently concentrated in the northwest of the EEZ. This distribution closely aligns with recent satellite-derived vessel tracking data which suggests that a regional longline fishing hotspot remains in the high seas area adjacent to the northwest of the Ascension Island MPA. Our results suggest that predatory pelagic fish and sharks will be the most direct beneficiaries of the Ascension Island MPA, although the high mobility of these species may lessen any conservation impacts, given intense the fishing effort in adjacent high seas areas. While illegal fishing remains a potential threat, the spatiotemporal predictability of the historic fishery may be useful in identifying areas of elevated risk for targeted enforcement in this large, remote MPA.</p>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aqc.70076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
