description This study evaluated the sex ratio and seasonal abundance of the seabob shrimp Xiphopenaeus kroyeri at the mouth of the São Francisco River, Northeastern Brazil, from 2008 to 2009. A total of 3,072 individuals were collected, measured for carapace length (in mm), and classified by sex and developmental stage. Shrimps were categorized according to the capture period (dry or rainy season). Size distribution ranged from 8-34 mm, with the highest concentration in the 18-20 mm class. Females were significantly more abundant and larger, predominating in most size classes. Juveniles represented 3.5% of the specimens, being more frequent in the dry season. There was no difference in adult participation between the analyzed periods. The dominance of females may be influenced by fishing selectivity, which tends to capture larger individuals. This study provides insights for the sustainable management of X. kroyeri stocks, highlighting the importance of management measures to maintain population viability, especially in the face of overfishing of reproductive stocks.

Foram coletados 3.072 indivíduos, medidos em comprimento da carapaça (em mm) e classificados por sexo e estágio de desenvolvimento. Os camarões foram categorizados conforme o período de captura (seco ou chuvoso). A distribuição de tamanho variou entre 8-34 mm, com maior concentração na classe de 18-20 mm. Fêmeas foram significativamente mais abundantes e maiores, predominando na maioria das classes de tamanho. Juvenis representaram 3,5% dos espécimes, sendo mais frequentes no período seco. Não houve diferença na participação dos adultos entre os períodos analisados. A dominância de fêmeas pode ser influenciada pela seletividade da pesca, que tende a capturar indivíduos maiores. Este estudo fornece subsídios para a gestão sustentável do estoque de X. kroyeri, ressaltando a importância de medidas de manejo para manter a viabilidade das populações, especialmente em face da sobrepesca dos estoques reprodutivos.Arquivos de Ciências do MarSex ratio and seasonal abundance of seabob shrimp Xiphopenaeus kroyeri lato sensu (Decapoda: Penaeidae) in the Northeastern Brazilian Coastal EcoregionRazão sexual e abundância sazonal do camarão sete-barbas Xiphopenaeus kroyeri lato sensu (Decapoda: Penaeidae) na Ecorregião Costeira do Nordeste Brasileiroinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleCamarãoDimorfismo sexualClasses de comprimentoSazonalidadeDinâmica populacionalShrimpSexual dimorphismLength classesSeasonalityPopulation dynamicsinfo:eu-repo/semantics/openAccessporreponame:Repositório Institucional da Universidade Federal do Ceará (UFC)instname:Universidade Federal do Ceará (UFC)instacron:UFCMelo-Lima, Valeria MariaMata-Oliveira, Igor daFrédou, Flavia LucenaCoelho Filho, Petrônio AlvesORIGINAL2024_art_vmmelolima.pdf2024_art_vmmelolima.pdfapplication/pdf1718083http://repositorio.ufc.br/bitstream/riufc/79527/1/2024_art_vmmelolima.pdfaecf1fb7a258f1dc909f3348688dac20MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748http://repositorio.ufc.br/bitstream/riufc/79527/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52riufc/795272025-01-27 10:58:38.1oai:repositorio.ufc.br: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Repositório InstitucionalPUBhttp://www.repositorio.ufc.br/ri-oai/requestbu@ufc.br || repositorio@ufc.bropendoar:2025-01-27T13:58:38Repositório Institucional da Universidade Federal do Ceará (UFC) - Universidade Federal do Ceará (UFC)false
