Resumo: | The coastal area is of fundamental importance for communities living in and dependent on it economically. The artisanal fishing is one of the activities most practiced by the riverside, which represents one of the main sources of income, besides the fishermen possess knowledge about the environment and the species used. The communities around the Mamanguape River estuary (ERM) also survive through the shellfish, which is of great social and economic importance, since it is a livelihood activity. ERM shellfishes use two main techniques for catching shellfish, both manual and jereré, a technique that promotes trawling on the substrate of the estuary, resulting in an accompanying biota. In this context, the objective was to analyze quantitatively and biometrically the shellfish resulting from the jereré trawls and their accompanying biota (bycatch). The shellfish were collected in the ERM through four collection expeditions, carried out between May 2017 and April 2018, in sand-mud banks known as Croa do Aberto, Croa do Meio and Croa dos Três Cambitos, where in each collection site was carried out five trawls with the petrecho, to obtain the seafood and its companion biota. The sizes of the shellfish were measured through a manual pachymeter and the biomass was performed using the calcined weight technique; the companion biota was identified through specialized bibliographic materials. The results showed that the shellfish presented larger sizes in the rainy season and greater abundances and biomasses in the dry period, and that by average size are apt to be captured. The organisms registered and identified in the accompanying biota belong to several taxa, such as Mollusca, Ostheichtys, Anellida, Echinodermata, Crustacea and Macroalgae. The importance of this study is to contribute to the improvement of the management and management of shellfish fishing, with the fishermen, in order to prevent future damages to the environment, species and riverine families that depend on this resource. |

A pesca artesanal é uma das atividades mais praticadas pelos ribeirinhos, a qual representa uma das principais fontes de renda, além dos pescadores possuírem conhecimento acerca do ambiente e das espécies utilizadas. As comunidades do entorno do estuário do Rio Mamanguape (ERM) sobrevivem, também, através da mariscagem, sendo esta de grande importância social e econômica, uma vez que é uma atividade que proporciona um meio de vida. Os marisqueiros do ERM utilizam duas principais técnicas para a captura do marisco, a manual e a do jereré, técnica que promove um arrasto no substrato do estuário, tendo como consequência uma biota acompanhante. Diante deste contexto, objetivou-se analisar quantitativa e biometricamente os mariscos resultantes dos arrastos do jereré e, sua biota acompanhante (bycatch). Os mariscos foram coletados no ERM através de quatro expedições de coleta, realizadas entre os meses de maio de 2017 e abril de 2018, em bancos areno-lodosos conhecidos como: Croa do Aberto, Croa do Meio e Croa dos Três Cambitos, onde em cada sítio de coleta foram realizados cinco arrastos com o petrecho jereré, para a obtenção dos mariscos e de sua biota acompanhante. Os tamanhos dos mariscos foram medidos através de um paquímetro manual e a biomassa foi realizada através da técnica do peso calcinado; a biota acompanhante foi identificada através de materiais bibliográficos especializados. Os resultados mostraram que os mariscos apresentaram maiores tamanhos no período chuvoso e maiores abundâncias e biomassas no período seco, e que pela média de tamanho estão aptos para captura. Os organismos registrados e identificados da biota acompanhante pertencem a vários táxons, como: Mollusca, Ostheichtys, Anellida, Echinodermata, Crustacea e Macroalgas. A importância desse estudo está em contribuir para a melhoria da gestão e manejo da pesca de mariscos, junto aos pescadores, na intenção de prevenir futuros danos ao ambiente, às espécies e às famílias ribeirinhas que dependem deste recurso.Submitted by Jean Medeiros (jeanletras@uepb.edu.br) on 2021-09-21T12:52:50Z No. of bitstreams: 1 PDF - Nathalia Racquel de Oliveira Rocha.pdf: 2157360 bytes, checksum: 084b978cd972ce24e66f3d4e78e95c80 (MD5)Approved for entry into archive by Rosalvo Andrade (rosalvo_andrade@servidor.uepb.edu.br) on 2021-11-11T19:33:50Z (GMT) No. of bitstreams: 1 PDF - Nathalia Racquel de Oliveira Rocha.pdf: 2157360 bytes, checksum: 084b978cd972ce24e66f3d4e78e95c80 (MD5)Made available in DSpace on 2021-11-24T23:53:45Z (GMT).

The coastal area is of fundamental importance for communities living in and dependent on it economically. The artisanal fishing is one of the activities most practiced by the riverside, which represents one of the main sources of income, besides the fishermen possess knowledge about the environment and the species used. The communities around the Mamanguape River estuary (ERM) also survive through the shellfish, which is of great social and economic importance, since it is a livelihood activity. ERM shellfishes use two main techniques for catching shellfish, both manual and jereré, a technique that promotes trawling on the substrate of the estuary, resulting in an accompanying biota. In this context, the objective was to analyze quantitatively and biometrically the shellfish resulting from the jereré trawls and their accompanying biota (bycatch). The shellfish were collected in the ERM through four collection expeditions, carried out between May 2017 and April 2018, in sand-mud banks known as Croa do Aberto, Croa do Meio and Croa dos Três Cambitos, where in each collection site was carried out five trawls with the petrecho, to obtain the seafood and its companion biota. The sizes of the shellfish were measured through a manual pachymeter and the biomass was performed using the calcined weight technique; the companion biota was identified through specialized bibliographic materials. The results showed that the shellfish presented larger sizes in the rainy season and greater abundances and biomasses in the dry period, and that by average size are apt to be captured. The organisms registered and identified in the accompanying biota belong to several taxa, such as Mollusca, Ostheichtys, Anellida, Echinodermata, Crustacea and Macroalgae. The importance of this study is to contribute to the improvement of the management and management of shellfish fishing, with the fishermen, in order to prevent future damages to the environment, species and riverine families that depend on this resource. |
