Low temperatures are related to the diminution of the burrowing activity of callianassids. Such short larval development explains the peak of recruitment right after the peak of ovigerous females. In April and from July to Novemberno difference in the frequency of juveniles and adults was detected. This superexploitation of the species may not allow the population to reach their dallichirus sizes.

A modification of Bhattacharya’s method for the analysis of mixtures of normal distributions. We can conclude that the females are more abundant in the population, which is a pattern for callianassids of the Brazilian coast. Although not significant, it was considered regularly correlated. Callchirus periods usually occur in seasons with high temperatures, since the temperature favors the sexual activity and embryonic development, as described by Hill for Upogebia africana Ortmann, and Tamaki et al.

However, they observed monthly oscillations in the sex ratio; callichiru females were more abundant from September to February and the males, from March to September, and in this study, the females callichirhs more abundant in March, with ovigerous females in March and November, and males more abundant in August, October, February and May.

Portunidae in a Brazilian tropical estuary. At the laboratory, the individuals were identified and sexed according to Melo According to Poseylow temperatures reduce the metabolism of ghost shrimps. According to Hill and Poseysalinity can exert a strong effect in the population of callianassids, due to its seasonal variations. Services on Demand Journal.

Callianassidae na Praia de Piedade, Brasil. Esta faixa foi dividida em cinco setores: Biologia populacional de Callichirus major Say, Crustacea: According to Wennerthe deviations in the sex ratio can be a result of the differences in the life cycle, migration, mortality and growth.

The amjor decreased only at the sector that presented greater extractive activity. The distribution of ghost shrimps by size class was not normal, i.

The aim of this paper was to analyze some aspects of the life cycle of C. The sex ratio observed in our study corroborates these studies.
