Abstract

Aim: The objective of this study was to characterize the sport-fishing tournament “Amigos do Tarumã” over the nine tournaments held between 2014 and 2023 in the state of Amazonas. This research generated the first report on the dynamics of peacock bass (Cichla sp.) catches at the Amigos do Tarumã tournament in the state of Amazonas, Brazil, over nine events between 2014 and 2023.

Methods: The data were provided by the organizer and creator of the event, with additional documents being obtained from the Institute of Environmental Protection of Amazonas and the State Secretariat for the Environment of Amazonas. Catches were recorded for each team and year, and statistical analyses were performed using descriptive analysis and the Kruskal-Wallis test to verify possible differences in total length (cm) over the years. About 1,700 fishers participated in the nine tournaments, with 1,240 peacock bass being caught, of which 726 were measured.

Results: The total lengths recorded ranged between 30 and 75 cm. There were significant differences in the average total length of the peacock bass only in the tournaments between 2014 and 2019 (P < 0.05).

Conclusions: In addition, the results suggest that, as a precautionary measure, tournaments that target peacock bass (Cichla sp.) should adopt the minimum catch size of 32 cm, in order to guarantee sustainability and the conservation of the peacock bass stock in the region.

Resumo

Objetivo: O objetivo deste estudo foi caracterizar o torneio de pesca esportiva “Amigos do Tarumã” ao longo dos nove torneios realizados entre 2014 e 2023 no estado do Amazonas. Esta pesquisa gerou o primeiro registro da dinâmica de capturas de tucunarés (Cichla sp.) realizadas no Torneio Amigos do Tarumã no Estado do Amazonas, Brasil, ao longo de nove edições entre 2014 e 2023.

Métodos: Os dados foram fornecidos pelo organizador e idealizador do evento, com documentos adicionais obtidos do Instituto de Proteção Ambiental do Amazonas e Secretaria de Estado do Meio Ambiente do Amazonas. As capturas foram registradas para cada equipe e ano, e análises estatísticas foram realizadas usando análise descritiva e teste de Kruskal-Wallis para verificar possíveis diferenças entre o comprimento total (cm) ao longo dos anos. Cerca de 1,700 pescadores participaram das nove edições, nas quais capturaram 1,240 tucunarés, com 726 sendo medidos.

Resultados: Os comprimentos totais registrados variaram entre 30 e 75 cm. Houve diferenças significativas no comprimento total médio dos tucunarés apenas entre as edições de 2014 e 2019 (p<0.05).

Conclusões: Além disso, os resultados sugerem que, como medida de precaução, torneios que tenham como alvo os tucunarés (Cichla sp.) devem adotar o tamanho mínimo de captura de 32 cm, visando à sustentabilidade e a conservação do estoque de tucunarés na região.
