Here, we used Passive Integrated Transponder (PIT) telemetry to examine lake-use patterns and their associations with survival and growth in juvenile Atlantic salmon Salmo salar L. over 3 years in the Burrishoole catchment, western Ireland. A fixed antenna positioned at the transition between river and lake habitats allowed us to estimate the timing of lake entry into Lough Feeagh - the largest freshwater lake in the system through which the fish must migrate on their way to the sea. Fish entering the lake earlier took longer to reach downstream sea-entry traps, a pattern consistent across years. Earlier entry was associated with a lower probability of detection at the downstream traps, which may reflect seasonal timing itself (e.g., seasonal variation in food availability or predation), cumulative mortality associated with prolonged lake residence (e.g., increased exposure to predators or other lake-specific risks) or intrinsic differences among early- and late-migrating fish (e.g., physiological attributes). Fish also exhibited substantially greater growth between upstream river exit and downstream recapture than inferred growth rates prior to lake entry, indicating that the lake can provide important feeding and growth opportunities during downstream migration. These findings are consistent with a potential trade-off between growth benefits and survival costs during lake passage, although this trade-off remains to be demonstrated directly. Overall, our results show that Lough Feeagh is more than a migration corridor for Atlantic salmon smolts and highlight the need to understand how seasonal timing, lake residence and individual characteristics jointly shape the costs and benefits of lacustrine habitat during anadromous migration.</p>","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149227817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zooplankton samples were collected during the day and night at 58 stations in October 2022. Based on morphological characteristics such as meristics and pigmentation, seven Symphurus morphotypes were pre-classified and genetically analysed using the mitochondrial genes cytochrome c oxidase subunit I (COI) and 16S rRNA (16S). Genetic analysis identified four morphotypes: three of them corresponded to a single species, Symphurus williamsi, with 100% similarity in the 16S gene, while the other morphotype was identified as Symphurus chabanaudi, with 100% similarity in both markers (COI and 16S). The pigmentation patterns described after molecular identification were consistent and allowed differentiation between the two species. S. williamsi presented three to five strongly stellate melanophores on the dorsal side and five to six melanophores on the ventral side during the preflexion to postflexion stages, while S. chabanaudi had three prominent melanophores in the central part of the notochord (lateral line), as well as a series of small melanophores positioned on the dorsal and ventral sides. S. williamsi larvae were located throughout the entire entrance to the Gulf of California, mainly in Transitional Water, while Symphurus chabanaudi was collected only in La Bahía de la Paz in Gulf of California Water.

Given the increasing incidence of hypoxia in its aquaculture setting, understanding the molecular mechanisms underlying gill adaptation to hypoxic stress is critical for improving resilience in this species. To achieve this, we employed full-length transcript sequencing using PacBio Iso-Seq and high-throughput Illumina RNA-Seq to construct a comprehensive transcriptome profile. Histological analyses revealed apparent structural alterations in gill tissues under hypoxic stress (dissolved oxygen: 2.0 ± 0.5 mg/L, duration: 96 h), including curved and swollen gill filaments, apoptosis and epithelial cell vacuolation. Comparative transcriptomic analysis revealed pronounced shifts in the expression of genes involved in energy metabolism, angiogenesis, immune responses, cell proliferation and apoptosis. Notably, the down-regulation of genes associated with cell cycle and proliferation suggests that M. salmoides may conserve energy by suppressing cell division under hypoxic conditions. In contrast, the increased expression of apoptosis-related genes, including casp7, indicates that apoptosis may play a protective role in maintain tissue homeostasis under hypoxia. Furthermore, the suppression of chemokine-mediated immune pathways implies that hypoxia redirects energy toward essential metabolic processes at the cost of local immune responses. GO and KEGG enrichment analyses identified TNF-α and chemokine-mediated signalling pathways as key pathways involved in tissue homeostasis and adaptive responses to hypoxic stress. These findings enhance our understanding of the mechanisms underlying hypoxia adaptation and provide valuable genetic resources for breeding strategies aimed at enhancing hypoxia tolerance in M. salmoides.</p>","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149220388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In riverine ecosystems, however, the ecological influence of ecotones on fish assemblages remains unpredictable due to highly dynamic hydrological regimes and strong species dispersal capacities, leaving the community assembly processes within these transition zones poorly understood. Here, we utilized an extensive dataset covering 20 sampling sites and six surveys over 2 years from China's large riverine floodplain ecosystem (the Yangtze River-Poyang Lake Riverine Floodplain). We aimed to characterize the spatial turnover of fish communities across a natural 45-km channel ecotone and its connected river and lake habitats, and to explore the underlying mechanisms driving these patterns. Using a split-moving window dissimilarity analysis (SMWDA), we detected an abrupt, non-linear breakpoint in community composition along the distance gradient from river to lake. Within the channel ecotone itself, we observed a localized decline in community diversity, indicating a sharp spatial turnover rather than a uniform distance-decay transition. Furthermore, threshold indicator taxa analysis (TITAN) revealed that this ecotonal transition significantly influenced rheophilic and lake–river migratory species, spanning an influence distance of approximately 92 km. The neutral community model (NCM) demonstrated that dispersal processes played a dominant role in shaping fish communities across all habitats, highlighting the water channel as a vital connectivity corridor for floodplain fish expansion. Overall, our study reveals that the channel in the Yangtze River-Poyang Lake Riverine Floodplain does not function as a classic high-diversity ecotone, but rather emphasizes the critical importance of water channels in supporting regional metacommunity dispersal.</p>","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":"109 4","pages":"1965-1977"},"PeriodicalIF":1.9,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148447409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, an unknown proportion of eels grow in marine coastal waters during the continental part of their lifecycle and therefore start their spawning migration while they are already in marine waters. To study the onset of the European eel's spawning migration in marine waters, we tagged yellow eels in Sandnesfjord, Norway. One hundred yellow and pre-migratory eels (stage FII or FIII) were tagged with acoustic transmitters in August, September or October in 2018–2019 and their subsequent movements were recorded within a hydrophone array until May 2023. Twenty-two eels left the fjord in a period spanning from early October to early December, which partly coincides with the usual downstream migratory period among European eels. These eels were never detected again and had thus presumably transitioned to the silver eel stage. This transition occurred from a few months to up to 3 years after tagging. In all silver eels, an increase in vertical and horizontal movements within the fjord preceded their exit from the fjord. This sudden increase in activity occurred only for a few days before they left the fjord in most individuals, but this period was as long as 1 month in other individuals. Five of the silver eels undertook migrations up to several kilometres to a tidal stream before leaving the fjord. Eel migration was largely nocturnal, independent of moon or tidal phase. We conclude that the relatively short migration season and individual migration duration within the fjord, combined with the absence of significant environmental, physiological or anthropogenic stressors, may contribute to higher survival rates during the continental phase of the spawning migration compared to eels that start their spawning migration from fresh water, but this needs to be investigated in future studies.</p>","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":"109 4","pages":"2004-2016"},"PeriodicalIF":1.9,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148471032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While ecologists have known that these invasive species have had deleterious effects on the ichthyofauna of Lake Titicaca for decades, whether this is a consequence of competitive exclusion or direct predation remains unknown. We tested this using morphological data, testing whether the closeness of native species to invasives in morphospace was predictive of their current conservation status, and whether smaller species were likelier to be at risk than larger species. We also tested whether fisheries pressure better explained extinction risk and found species that were at higher risk of extinction were fished less than those which were at a lower risk of extinction. We found that larger species, and those closer to the invasives in morphospace, are likelier to be endangered or to have gone extinct. This strongly suggests that competitive exclusion is the primary way that invasive species cause native fish declines in Lake Titicaca. Using morphospace to assess the mechanisms of invasive species' impacts on native fish species is an alternative to longer-term monitoring which is often absent in poorly studied, though highly diverse, tropical waters.

Coastal shelf seas, where most OWFs are constructed, often overlap with essential elasmobranch habitats, including complex biogenic structures such as mussel beds that provide foraging and refuge opportunities.

These findings show that <i>S. canicula</i> juveniles show no preference in substrate or alternating-current EMF exposure, but they did subtly change their behaviour.
