Resumo: In the Amazon region the Peacock Bass (Cichla spp) is highly appreciated in commercial and sport fishing, so understanding its biological characteristics is essential for the management and conservation of the species. This work aimed to analyze the situation of the stock and fishing dynamics of peacock bass, marketed in the fishing market of Porto Velho (Rondônia), in the period from 2011 to 2020. Growth rates (length of and weight) identified the stock indicators and parameters. The inventory indicators show that the years 2011 and 2017 presented higher values in the age of first maturation, with an average of 20%, 2013 presents a better capture, being 7.6% at the age of first maturation, only the years 2012, 2013 and 2017 were with the percentages of ideal capture (Popt), being 60, 79 and 69% respectively, where the reference values are 60 to 80%, but the inventory indicator (Pobj) showed overfishing in all years, standing out in 2011 and 2018 with the highest overfishing rate. The results indicate that peacock bass, in the study region are overfished, what require fishing monitoring and management aiming at the protection of the stock.

Este trabajo tuvo como objetivo analizar la situación del stock y la dinámica pesquera de la lubina pavo real, comercializada en el mercado pesquero de Porto Velho (Rondônia), en el período de 2011 a 2020. Se utilizaron las tasas de crecimiento (longitud y peso), se identificaron indicadores y parámetros de inventario. Los indicadores de inventario muestran que los años 2011 y 2017 tuvieron los porcentajes de captura ideales (Popt), siendo 60, 79 y 69%, respectivamente, donde los valores de referencia son de 60 a 80%, pero el indicador de inventario (Pobj) mostró sobrepesca en todos los años presentes, destacándose 2011 y 2018 con la mayor tasa de sobrepesca. Los resultados indican que la lubina pavo real, en la región de estudio, está sobreexplotada o que requiere monitoreo y gestión de la pesca, con el objetivo de proteger la población.Na região amazônica o Tucunaré (Cichla spp) é bastante apreciado na pesca comercial e esportiva, com isso compreender suas características biológicas é essencial para o manejo e conservação da espécie. Este trabalho teve como objetivo analisar a situação do estoque e dinâmica pesqueira do tucunaré, comercializado no mercado pesqueiro de Porto Velho (Rondônia), no período de 2011 a 2020. Foram utilizadas as taxas de crescimento (comprimento e peso), identificadas os indicadores de estoque e parâmetros. Os indicadores de estoques mostram que os anos de 2011 e 2017 apresentaram valores maiores na idade de primeira maduração, com média de 20%, 2013 apresenta uma melhor captura, sendo de 7,6% na idade de primeira maturação, apenas os anos de 2012, 2013 e 2017 ficaram com as porcentagens de captura ideal (Popt), sendo 60, 79 e 69% respectivamente, onde os valores de referência são de 60 a 80%, porém o indicador de estoque (Pobj) mostrou sobrepesca em todos os anos apresentam, destacando-se 2011 e 2018 com a maior taxa de sobrepesca. Os resultados indicam que os tucunarés, na região de estudo, estão sobrepescados sendo necessário monitoramento e gestão pesqueira, visando a proteção do estoque.Research, Society and Development2022-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3397110.33448/rsd-v11i12.33971Research, Society and Development; Vol. 11 No. 12; e12111233971Research, Society and Development; Vol. 11 Núm. 12; e12111233971Research, Society and Development; v. 11 n. 12; e121112339712525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/33971/28781Copyright (c) 2022 Kassio Pereira das Neves; Igor Rechetnicow Alves Sant' Anna; Edson Rubens Ferreira Rodrigues; Carolina Rodrigues da Costa Doriahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNeves, Kassio Pereira dasSant' Anna, Igor Rechetnicow Alves Rodrigues, Edson Rubens Ferreira Doria, Carolina Rodrigues da Costa2022-09-26T11:56:08Zoai:ojs.pkp.sfu.ca:article/33971Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:49:27.297424Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
