Resumo: Biological aspects and fishing information of timbiro Pterengraulis atherinoides from Pereira de Miranda reservoir, Pentecoste, Ceará State, Brazil, were studied in the present work. Monthly samples were obtained from August 1994 to July 1995. During this period 5,140 individuals were analyzed. Based on each species’ morphometrical data, the following parameters were estimated using projection models: growth, mortality, exploration rate, capture probability, recruitment and fishing effort intensity. A frequency distribution table on length was elaborated and analyzed by FAO-ICLARM Stock Assessment Tools - FISAT. P. atherinoides has been shown to be a medium-life fish whose growth rate is quite high. Both natural and fishing mortality rates are coherent to other growth parameters, as it is a commercially unexplored resource. Individuals have been captured before they reach their first gonadal maturation, due to the low selectivity of fishing apparatus. Since timbiro is highly proliferous, this fact has kept the population in natural equilibrium

Coletas mensais foram realizadas durante o período de agosto de 1994 a julho de 1995. Com os dados morfométricos, uma distribuição de freqüência de comprimento foi feita para ser analisada através do Programa FAO-ICLARM Stock Assessment Tools - FISAT. Assim, os seguintes parâmetros foram estimados: crescimento, mortalidade, taxa de exploração, probabilidade de captura, recrutamento e intensidade do esforço de pesca. Desta forma, conclui-se que a espécie possui vida curta e uma taxa de crescimento alta. Os coeficientes de mortalidade natural e por pesca mostraram-se equilibrados, por se tratar de um estoque não explorado comercialmente. Mesmo com um tamanho médio de primeira captura abaixo do valor do de primeira maturação gonadal, que se deve à baixa seletividade da rede-de-espera, a espécie é muito prolífera, garantindo, assim, o equilíbrio da populaçãoEditora da Universidade Estadual de Maringá2008-03-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/115610.4025/actascianimsci.v27i4.1156Acta Scientiarum.
