PRELIMINARY NOTE ON THE Carcinus aestuarii IN VARANO LAGOON: POPULATION STRUCTURE AND REPRODUCTIVE

Abstract

This study analyses some aspects of Carcinus aestuarii biology within the project MOLEVAR funded byFEP ( European Funds for Fishing) in order to evaluate the crabs, Carcinus aestuarii, as a new economicresource for Varano Lagoon (S Italy). The population structure and reproductive biology of this specieswill be studed in three different sites of the lagoon. A total of 148 specimens were obtained from May toAugust 2012; 139 males and 9 females were observed. Length (CL) and width (CW) of the carapace andtotal weight (TW), were determined sex and development stage. At the same time, water temperature,salinity, oxygen concentration and pH were measured with a multiparametric probe. The reproductivebiology of C. aestuarii will be performed through the histological study of the reproductive cycle of thefemale and will be calculated the sex ratio.
