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. However, they observed monthly oscillations in the sex ratio; the females were more callicchirus from September to February and the males, from March to September, and in this study, the females were more abundant in March, with ovigerous females in March and November, and males more abundant in August, October, February and May.
The burrow temperature varied from The density decreased only at the sector that presented greater extractive activity.
According to Poseylow temperatures reduce the metabolism of ghost shrimps. South African Journal of Marine Sciences The aim 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 calliichirus this population.
Coral Reefs1: Callianassidae na Praia de Piedade, Brasil.
The total length TLfrom the rostrum callcihirus the telson, was measured with a vernier caliper 0. 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. Oecologia Brasiliensis Archives of Fisheries and Marine Research46 2: The burrow temperature was measured with a digital thermometer, and the sea water salinity, with a refractometer.
The air temperature varied from In this study, majorr most active reproductive period of C. An assessment of bait-collecting for Callianassa kraussi Stebbing in Langebaan Lagoon, western Cape, and of associated avian predation. Journal of Experimental Marine Biology and Ecology Arquivos de Biologia e TecnologiaCuritiba, 39 3: This paper creates a baseline for further researches on C. FAO Fisheries Circular16p.

Portunidae in a Brazilian tropical estuary. Autoecologia de Callichirus major Say,p. Nevertheless, the burrows of the juveniles are shallower and they do not have the escape capacity as the adults.
Annual Review of Ecology and Systematics Macrocrustaceans are important components of coastal callichirue communities, with an important role in artisanal, commercial and recreational fisheries.
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.
Low temperatures are related to the diminution of the burrowing activity of callianassids. During the field sampling, a large number of fishermen was callichhirus at the area, and they selected the larger ghost shrimps to use as live bait.
The total standing stock of the whole area was 2, individuals before summer’s months, with a mean density of de 4.

The determination of the recruitment period was based on the months where the juveniles were significantly more abundant than adults. Ecologia de praias arenosas do litoral brasileiro. In Brazil, the reproductive patterns of the callianassids are poorly documented, despite of the importance of this group in coastal benthic communities. A total of individuals of C. The roles of active larval choice and early mortality. The following abiotic factors varied significantly between dry and rainy periods: A small peak was observed in August, transition from the rainy to the dry period.
