Resumo: | The snook fish occurs in the Sergipe river estuary, and is important resource for artesanal fishing landings in the port of Bairro Industrial, Aracaju-SE. The purpose of this work was to analyze the capture of snook fish in the Sergipe river estuary. The production data were obtained through the records of landings in the port of Bairro Industrial from April/2016 to December/ 2017. A total of 562 individuals were collected to obtain biometric data (CT, PT) and identified. For the two most representative snook species at landings length frequency distribution, weight-length relation, and the monthly average of condition factor K were established. The catch-per-unit data (CPUE) calculated for each landing was log-transformed (LOGCPUE +1) and compared with ANOVA. The species of snooks present in the captures were the fat snook Centropomus parallelus (62% of the individuals), common snook C. undecimalis (35%) and tarpon snook C. pectinatus (3%). C. parallelus showed TL range of 20.0 to 60.0 cm. The mean of the condition factor K for individuals with a CT> 28.0 cm was 10.7 ± 1.1. The TC amplitude of C. undecimalis was 20.0 to 105.0 cm, with mean K of 3.25 ± 0.28. For both species, there was a significant contribution of individuals below the size of first maturation. The small mesh size of the beach drag (20 mm) may be contributing to the substantial presence of small individuals in catches. The main catch areas of sea bass on the Sergipe River are located in places with high organic matter concentration and low oxygen content. For beach trawls, the rainfall period influenced CPUE variation. Most of the gillnet catches were concentrated in the Sergipe river channel and were less affected by habitat reduction in the dry season. |

O objetivo deste trabalho foi analisar as capturas de robalo, no estuário do Rio Sergipe. Os dados de produção foram obtidos através dos registros de desembarques, no Bairro Industrial, de Abril/2016 a Dezembro/2017. Um total de 562 indivíduos foi coletado para obtenção de dados biométricos (CT, PT) e identificados. Para as duas espécies mais representativas, nos desembarques, foram estabelecidas a distribuição de frequência, a relação peso-comprimento e a média mensal do fator de condição K. Os dados de captura por unidade de esforço (CPUE), calculados para cada desembarque, foram LOG transformados (LOGCPUE+1) e comparados com ANOVA. As espécies de robalos presentes nas capturas foram o robalo-corcunda Centropomus parallelus (62% dos indivíduos), robalo- -furador C. undecimalis (35%) e robalo-alfaiate C. pectinatus (3%). C. parallelus apresentou amplitude de CT de 20,0 a 60,0 cm. A média do fator de condição K para os indivíduos com CT > 28,0 cm foi de 10,7±1,1. A amplitude de CT de C. undecimalis foi de 20,0 a 105,0 cm, com K médio de 3,25±0,28. Para ambas as espécies, houve uma contribuição significativa de indivíduos abaixo do tamanho de primeira maturação. O pequeno tamanho de malha do arrasto de praia (20 mm) pode estar contribuindo para presença significativa de indivíduos de pequeno porte nas capturas. As principais áreas de captura de robalo, no Rio Sergipe, estão situadas em locais com alta concentração de matéria orgânica e baixos teores de oxigênio. Para rede de arrasto de praia, o período pluviométrico influenciou na variação da CPUE. A maioria das capturas das redes de emalhe se concentrou no canal do rio Sergipe e foi menos influenciada pela redução do habitat, no período seco.Instituto de Ciências do Mar2019-05-24T17:19:53Z2019-05-24T17:19:53Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPINTO, J.
