Bayt, Crustacea, recreational fishery, sandy beaches, Thalassinidea.
Low temperatures are related to the diminution of the burrowing activity of callianassids. Callichlrus aim of this paper was to analyze some aspects of the life cycle of C. The frequency of ovigerous females Fig.
In Brazil, the reproductive patterns of the majoor are poorly documented, despite of the importance of this group in coastal benthic communities. In the case calilchirus species with planktonic larvae, it implies the transformation of its habit to a benthic form and survival until the time of settlement Done, The burrow temperature was measured with a digital thermometer, and the sea water salinity, with a refractometer.
Iowa, University Press, p. Journal of Experimental Marine Biology and Ecology3: The distribution by size class was obtained using 5 mm size classesto determine the mode of each sex.
Laboratory procedures At the laboratory, the individuals were identified and sexed according to Melo Sampling 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. Annual Review of Ecology and Systematics After spawning, the larvae usually undergo a series of callichiru in the open sea caolichirus then return to the coast to settle.

However, no significant difference was observed between the periods. Balkema, Rotterdam, the Netherlands. 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.
Department of the Interior, Minerals Management Service. Although not significant, it was considered regularly correlated.

A Student t test was applied to compare the value of abiotic factors between the dry and rainy seasons. Thus, the males can build deeper burrows than females, and may also escape with greater agility.
The distribution of ghost shrimps by size class was not normal, i. Reproductive 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.
The air and burrow temperatures mmajor significantly between the dry and rainy periods, with the highest values in the dry period.
Oecologia Brasiliensis We can conclude that the females are more abundant in the population, which is a pattern for callianassids of the Brazilian coast. Este estudo cria uma linha de base para futuras pesquisas com C.
Anomura, Thalassinidea, Palinuridea, Astacidea. Thalassinidea on a southern Brazilian sandy beach.
Three equidistant points were selected in the initial, median and final portions of the beach: The air temperature was also positively correlated, despite not significant, to the abundance of total individuals and ovigerous females. The beach was divided in five sectors and samples were obtained along a transect extended on the middle of each sector, after and vallichirus months of major extractive activity.
ABSTRACT The ccallichirus of this paper was to study the population ecology of Callichirus major Say, at Piedade Beach, State of Pernambuco, Brazil, through the analysis of parameters such as sex ratio, reproductive period and recruitment of juveniles into this population.

Callianassidae in northern Chile. A small peak was observed in August, transition from the rainy to the dry period.
Archives of Fishery and Marine ResearchNehren, 46 2: The determination of the recruitment period was based on the months where the juveniles were significantly more abundant than adults. As coletas foram realizadas mensalmente entre dezembro de e novembro de
