One of these ecoregions is the Parnaíba, which drains almost the entire state of Piauí, and part of the states of Maranhão and Ceará. Among the species of Hypostomus registered in this ecoregion, there is Hypostomus vaillanti. The type locality of H. vaillanti was assigned to the Rio Preto, a tributary of the median portion of the Rio São Francisco basin at the municipality of Villa de Santa Rita (currently Santa Rita de Cássia), Bahia State, Brazil. Despite these historical data, we only found H. vaillanti in the Rio Parnaíba basin. Some fish surveys were carried out in different times by the authors and by other skilled ichthyologists in the Rio Preto and other nearby rivers from the Rio São Francisco basin, and no specimen of H. vaillanti have been found. Additionally, although the original description of H. vaillanti was well written, searching its distinction from some congeners in the taxonomic literature is nowadays quite complicated. Therefore, this species is re-described, and a new diagnosis is provided based on the analysis of recently found specimens in addition to an analysis of the type material. A lectotype of the Plecostomus vaillanti is designated herein. The results suggest that the distribution of H. vaillanti is restricted to the Rio Parnaíba basin; furthermore, we provide a molecular phylogenetic analysis that highlights some relationships between H. vaillanti and closely related species.","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144317071","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}

This species plays a key role in the food web and its potential collapse could negatively affect commercially exploited species. To date, few studies have attempted to provide needed life-history information for this species' stock status evaluation. With this in mind, we collected the otoliths of 470 specimens caught along the coasts of the two larger Mediterranean islands (271 specimens in Sardinia and 199 in Sicily). Age readings showed good reproducibility (index of average percent error = 11.4%, reading agreement 86.7%). For the first time, age-at-length data from this species were employed in a multi-model inference analysis. Von Bertalanffy's function outperformed the other examined models in terms of fitting the observed data. In both regions, there were no major differences in growth between sexes. The species exhibited a relatively rapid growth rate while having a short life span (3.5 years maximum recorded age in both locations). The obtained growth parameters for combined sexes were L∞ = 14.02 cm (TL), k = 0.45, t0 = -1.02 and L∞ = 11.76 cm (TL), k = 0.62, t0 = -1.43 in the Sardinian and Sicilian Seas, respectively. Shape analysis revealed that otolith morphology might distinguish between Sardinian and Sicilian populations, which warrants further investigation. The reconstructed otolith outlines differed significantly between the two sampled locations. These morphological discrepancies are most likely due to a mix of genetic and environmental factors.","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144275054","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}

Fish otoliths contain a natural biogeochemical record of ambient environmental conditions and habitat use over such scales. However, ecological interpretations of these elemental compositions can be influenced by the structural composition of calcium carbonate otoliths, which can vary between wild and aquaculture fish as well as across species. As such, we used in situ confocal micro-Raman spectroscopy and powder X-ray diffraction to assess and quantify, respectively, the calcium carbonate polymorphs of the otoliths of aquaculture and wild yellowtail kingfish (Seriola lalandi) to validate whether the otoliths from aquaculture fish can be used to interpret patterns seen in the otoliths of wild fish. We then analysed major and minor trace elements using wavelength dispersive X-ray spectroscopy to investigate the potential habitat use of wild S. lalandi. The elemental composition of S. lalandi otoliths was examined across three cross-sectioned growth zones: the first (i.e. oldest) annulus (growth ring), the outermost (i.e. most recent) annulus and mid-way between these. All otoliths were shown to be composed of aragonite, with the exception of small proportions (0.5 wt%) of vaterite in a single wild S. lalandi otolith. This finding indicates that otoliths of aquaculture S. lalandi, reared in known conditions, are appropriate to interpret stable isotope analyses in wild S. lalandi. Wild-caught S. lalandi otoliths had concentrations of barium and manganese below detectable limits (<0.2 and <0.01 wt%, respectively) inferring that S. lalandi were not in estuarine or brackish environments when the analysed annuli were formed, suggesting these environments are not used for spawning.","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144275068","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}

H. hudsonius has traditionally been regarded as one of the most basal and plesiomorphic species among the notropin fishes, that is, fishes traditionally placed in or associated with the large, polyphyletic genus Notropis, including but not limited to Alburnops, Cyprinella, Ericymba, Lythrurus, Miniellus and Paranonotropis. The basal nature of H. hudsonius has been further corroborated by recent molecular studies. The osteology of notropin fishes has either focused on a specific region of the skeleton, including the cranium, pharyngeal teeth and dental formulae, or the caudal skeleton. Others have aimed to determine evolutionary relationships using osteological characteristics. However, no research has focused on the osteology of H. hudsonius specifically nor emphasized the intraspecific osteology of a single notropin species. Thus, this study aimed to describe and analyse key osteological characters of H. hudsonius, highlighting key osteological variants within and among 15 populations from Alberta, the Northwest Territories, Manitoba and Ontario. Particular attention is given to the elements of the oral jaws, suspensorium, opercular series, branchial apparatus, hyoid region, circumorbital series, pectoral girdle, pelvic girdle, caudal skeleton and skull. My analysis of the osteology of H. hudsonius reveals variation in all examined regions except the pelvic girdle. Regional differentiation between eastern and western populations is especially evident in the degree of fusion of the pectoral girdle, fusion of the parhypural and first hypural of the caudal skeleton and shape of the urohyal. The results of this analysis provide an overview of the osteology of a basal notropin species and highlight which regions are subject to variation. It also raises further questions about the current taxonomic classification of H. hudsonius based on the regional differences observed here.","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266400","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}

Bones and teeth, in addition to bioapatite, contain carbonate and should retain a similar isotopic expression of metabolic rate. Chondrichthyan skeletons are cartilaginous, but in most species some degree of bio-apatite mineralisation of cartilage has been determined. Here we tested the potential to estimate the FMRs of chondrichthyan fishes from the isotopic composition of calcified cartilage. Our results indicate that δ13C values of vertebrae and jaws covary with assumed activity levels, body mass and temperature in a manner consistent with them being influenced by the metabolic rate of the organisms using δ18O values as a proxy. Highly active thunniform species had significantly more negative δ13Cvert (and higher Cresp) values than species with less active swimming types, conforming to expectations. Values of δ13C in carbonate from jaws were lower in immature elasmobranchs Raja asterias than in Mustelus sp., potentially reflecting mass effect differences in metabolic rates. Tooth enameloid showed anomalous carbon isotope compositions which imply direct exchange with dissolved inorganic carbon during crystal growth. Many knowledge gaps related to the relationships between structural tissue isotope compositions and carbon respiratory physiology of elasmobranch remain. However, our results provide evidence that carbon isotopes of structural carbonate in cartilaginous tissues of chondrichthyan fishes offer potential as a proxy for metabolic level.","PeriodicalId":15794,"journal":{"name":"Journal of fish biology","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266409","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}

Using the MitoFish reference database through the Global Biodiversity Information Facility querying tool, we identified 63 fish species and found significant changes in the dominant taxa between seasons and years. Clupea harengus (Atlantic herring) consistently peaked in early spring, while Scomber scombrus (Atlantic mackerel) dominated winter months in the second year. The MiFish primer set showed increased species richness in the second year, whereas the Elas02 primer set showed stable richness despite compositional turnover. Non-metric multidimensional scaling revealed distinct community separation between years in presence/absence of data, driven by species turnover rather than abundance read changes. Our findings support the use of eDNA metabarcoding to capture fine-scale (bi-monthly) temporal dynamics and emphasise the importance of multi-year datasets for distinguishing ecological trends from stochastic changes.
