Resumo: In this work, information on population structure, biometric, morphometric and density relationships are attributed as an indicator of the abundance of Colomesus psittacus and Sphoeroides testudineus, relating them to environmental variables, to verify possible interaction of the environment with the distribution of species. The collections were carried out from September 2012 to October 2013, using block-net gillnet. Analyzes of the averages (ANOVA, with an error of 5%) of total length (TL), weight (w) and abiotic variables were performed by different sources and statistical methods. Density, linear regression, sex ratio and size of first maturation (L50) were determined. 1,476 individuals, 1,367 C. psittacus and 109 S. testudineus were captured. The results were not significant when analyzing the number of individuals (N) by sex and total length (TL) by species. The relative frequencies of females and males were close to the expected 1: 1 for both species. The biometric and morphometric relationships had negative allometries, except for males of S. testudineus. The C. psittacus L50 was 14.72 cm. Evidently C. psittacus completes its entire life cycle in the estuary. However, S. testudineus demonstrated transitory habits within the estuary, being found abundantly in more saline months.

Las recolecciones se llevaron a cabo desde septiembre de 2012 hasta octubre de 2013, utilizando redes de enmalle en bloque. Los análisis de los promedios (ANOVA, con un error del 5%) de la longitud total (LT), el peso (g) y las variables abióticas se realizaron mediante diferentes fuentes y métodos estadísticos. Se determinó la densidad, regresión lineal, proporción de sexos y tamaño de primera maduración (L50). Se capturaron 1476 individuos, 1367 C. psittacus y 109 S. testudineus. Los resultados no fueron significativos al analizar el número de individuos (N) por sexo y la longitud total (LT) por especie. Las frecuencias relativas de hembras y machos estuvieron cerca del esperado 1: 1 para ambas especies. Las relaciones biométricas y morfométricas tuvieron alometrías negativas, excepto para los machos de S. testudineus. El C. psittacus L50 fue de 14,72 cm. Evidentemente C. psittacus completa todo su ciclo de vida en el estuario. Sin embargo, S. testudineus demostró hábitos transitorios dentro del estuario, encontrándose abundantemente en meses más salinos.Neste trabalho são atribuídas informações sobre a estrutura populacional, relações biométricas, morfométricas e densidade como indicador da abundância de Colomesus psittacus e Sphoeroides testudineus, relacionando-os às variáveis ambientais, para verificar possível interação do ambiente com a distribuição das espécies. As coletas foram realizadas no período de setembro de 2012 a outubro de 2013, utilizando rede de emalhar do tipo block-net. Realizaram-se análises das médias (ANOVA, com erro de 5%) de comprimento total (CT), peso (g) e varáveis abióticas por diversas fontes e métodos estatísticos. Determinou-se a densidade, regressão linear, proporção sexual e tamanho de primeira maturação (L50). Foram capturados 1.476 indivíduos, 1.367 C. psittacus e 109 S. testudineus. Os resultados não foram significativos quando analisados o número de indivíduos (N) por sexo e comprimento total (CT) por espécie. As frequências relativas de fêmeas e machos foram próximas do esperado de 1:1 para ambas as espécies. As relações biométricas e morfométricas tiveram alometrias negativas, exceto, para machos de S. testudineus. O L50 de C. psittacus foi 14,72 cm. Evidentemente C. psittacus completa todo seu ciclo de vida no estuário. No entanto, S. testudineus demonstrou hábitos transitórios dentro do estuário, sendo encontrado abundantemente, em meses mais salinos.Research, Society and Development2020-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/848710.33448/rsd-v9i10.8487Research, Society and Development; Vol. 9 No. 10; e3339108487Research, Society and Development; Vol. 9 Núm. 10; e3339108487Research, Society and Development; v. 9 n. 10; e33391084872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/8487/7662Copyright (c) 2020 Flávio Miranda Gonçalves ; Niedja Luana da Costa Mescouto; Mayra Sousa do Nascimento; Luciano de Jesus Gomes Pereira; Suélly Cristina Pereira Fernandes; Ítalo Antônio Freitas Lutz; Bianca Bentes https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGonçalves , Flávio MirandaMescouto, Niedja Luana da Costa Nascimento, Mayra Sousa doPereira, Luciano de Jesus Gomes Fernandes, Suélly Cristina Pereira Lutz, Ítalo Antônio Freitas Bentes , Bianca 2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8487Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:57.167939Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
