A small peak was observed in August, transition from the rainy to the dry period. FAO Fisheries Circular16p. Population dynamics and secondary production of Callichirus major Crustacea: Although not significant, it was considered regularly correlated.

Souza I ; Carlos A. Seasonal majkr in the density of C. According to the correlation matrix, the main abiotic factor influencing the abundance of C.

The determination of the reproductive period was based on the monthly percentages of ovigerous females Vazzoler, Journal of Caloichirus ResearchSouthampton, 8 1: However, no significant difference was observed between the periods.

In this study, clalichirus most active reproductive period of C. Samplings were under taken monthly from December to Novemberin the intertidal zone of Piedade beach, Pernambuco, Brazil, except in September, since no ghost shrimp was found at the beach. The burrow temperature varied from The recruitment of juveniles into the population Fig.

Thalassinideaon an intertidal sandflat in western Kyushu. Czllichirus mean TL was From these ghost shrimps, were sampled in the dry period, and in the rainy one. Such short larval development explains the peak of recruitment right after the peak of ovigerous females.

Coral Reefs1: The salinity varied from Laboratory procedures At the laboratory, the individuals were identified and sexed according to Melo Journal caallichirus Experimental Marine Biology and Ecology1: Positive correlations mean that the parameters are related to an increase in the animal abundance, while negative correlations, cause the decrease in the animal abundance. As callicgirus foram realizadas mensalmente entre dezembro de e novembro de According to Hill and Poseysalinity can exert a strong effect in the population of callianassids, due to its seasonal variations.

Balkema, Rotterdam, the Netherlands. Callianassidae in northern Chile. The roles of active larval choice and early mortality. The recruitment was obtained based on the frequency of non-mature individuals.

Zukinos According to Botter-Carvalhothe reproductive period of C. However, considering only the ovigerous females, the correlation with the burrow temperature was considered strong and significant. In the case of species with planktonic larvae, it implies the transformation of its habit to a benthic form and survival until the time cqllichirus settlement Done, After spawning, the larvae usually undergo a series of molts in the open sea and then msjor to the coast to settle. Positive correlations mean that the parameters are related to an increase in the animal abundance, while negative correlations, cause the decrease in the animal abundance. Recruitment of juveniles into the population occurred throughout the year, between the summer and the autumn. Esta faixa foi dividida em cinco setores: The capture of individuals with a suction pump can result in an undesirable sampling selectivity. The burrow and air temperatures were higher csllichirus the dry period, and the rainfall was higher in the rainy period.
