Resumo: The long-whiskered catfish Steindachneridion parahybae (Family Pimelodidae) is endemic to the Paraiba do Sul River basin in southeastern Brazil. This species was heavily exploited by artisanal fisheries and faces challenges posed by dams, introduced species, and deterioration of critical habitat. The remaining populations are small and extirpated from some locales, and the species is listed as critically endangered in Brazil. Screening variation at a partial mitochondrial control region sequence (mtCR) and 20 microsatellite loci, we: (i) describe the patterns of genetic diversity along its current distributional range

This species was heavily exploited by artisanal fisheries and faces challenges posed by dams, introduced species, and deterioration of critical habitat. The remaining populations are small and extirpated from some locales, and the species is listed as critically endangered in Brazil. Screening variation at a partial mitochondrial control region sequence (mtCR) and 20 microsatellite loci, we: (i) describe the patterns of genetic diversity along its current distributional range(ii) test the null hypothesis of panmixia(iii) investigate the main factors driving its current population structure, and (iv) propose management of broodstock for fostering recovery of wild populations through genetically cognizant restocking. Our microsatellite data for 70 individuals from five collections indicate moderate levels of heterozygosity (H-O = 0.45) and low levels of inbreeding (F-IS = 0.016). Individual-based cluster analyses showed clear genetic structure, with three clusters of individuals over the collection area with no mis-assigned individuals, suggesting no recent migration among the three clusters. Pairwise D-EST values showed moderate and significant genetic differentiation among all populations so identified. The MUR population may have suffered a recent demographic reduction. mtCRs for 70 individuals exhibited 36 haplotypes resulting from 38 polymorphic sites. Overall, mitochondrial haplotype diversity was 0.930 (+/- 0.023) and nucleotide diversity was 0.011 (+/- 0.002). Significant population structure was observed, with phi(ST) = 0.226. Genetic markers could be used in a hatchery-based restoration program emphasizing breeding of pairs with low kinship values in order to promote retention of genetic diversity and avoid inbreeding. Individual average kinship relationships showed 87.3% advised matings, 11.0% marginal matings, and 1.7% advised against. While these results comprise a contribution toward planning better breeding management and monitoring, parallel actions to be undertaken include surveying healthy riverine habits for reintroduction and continued searching for wild individuals to introduce new variation into the captive broodstock to avoid adaptation to captivity and to minimize inbreeding.Sao Paulo Research Foundation (FAPESP) [11/23752-2]AGEVAP [10/2012]FUNDEPAGInstituto de PescaUniv Mogi das Cruzes, Lab Genet Organismos Aquat & Aquicultura, Unidade Biotecnol, Nucleo Integrado Biotecnol, Mogi Das Cruzes, BrazilAgencia Paulista Tecnol Agronegocios, Inst Pesca, Secretaria Agr & Abastecimento Estado Sao Paulo, Sao Jose Do Rio Preto, BrazilUniv Fed Sao Paulo, Inst Mar, Santos, BrazilVirginia Polytech Inst & State Univ, Dept Fish & Wildlife Conservat, Blacksburg, VA 24061 USAUniv Fed Sao Paulo, Inst Mar, Santos, BrazilFAPESP [11/23752-2]AGEVAP [10/2012]Web of Science-engFrontiers Media SaFrontiers In GeneticsSteindachneridion parahybaesurubim-do-paraibaParaiba do Sul RiverSiluriformespopulation structureconservation aquacultureGenetic Diversity of an Imperiled Neotropical Catfish and Recommendations for Its Restorationinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleLausanne8info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UNIFESPinstname:Universidade Federal de São Paulo (UNIFESP)instacron:UNIFESPORIGINALWOS000417740300001.pdfapplication/pdf7667199${dspace.ui.url}/bitstream/11600/54000/1/WOS000417740300001.pdff9fda5dfba176533015ee69ee39d92e3MD51open accessTEXTWOS000417740300001.pdf.txtWOS000417740300001.pdf.txtExtracted texttext/plain64121${dspace.ui.url}/bitstream/11600/54000/5/WOS000417740300001.pdf.txtc633598a5d5f997c225d1c481d49f05fMD55open accessTHUMBNAILWOS000417740300001.pdf.jpgWOS000417740300001.pdf.jpgIM Thumbnailimage/jpeg6689${dspace.ui.url}/bitstream/11600/54000/7/WOS000417740300001.pdf.jpg18303cbd93951d71ec82c381ae2a446eMD57open access11600/540002023-06-05 19:38:27.665open accessoai:repositorio.unifesp.br:11600/54000Repositório InstitucionalPUBhttp://www.repositorio.unifesp.br/oai/requestopendoar:34652023-06-05T22:38:27Repositório Institucional da UNIFESP - Universidade Federal de São Paulo (UNIFESP)false
