Abstract

The blue crab Callinectes sapidus Rathbun is abundant along the Atlantic coast from Cape Cod to Uruguay (Gosner, 1978). The life cycle of C. sapidus is similar to that of many species which spawn in marine waters but whose young are estuarine dependent. Zoeae hatch from the eggs, develop into the megalopa stage and then into the first crab stage. The juveniles then migrate upstream into the estuary (Tagatz, 1968). The biology of the blue crab has been extensively researched because of its abundance and great commercial value. One area of current interest is the study of the relationship of size to weight, taking into consideration various environ- mental and intrinsic parameters. Several size-weight relationships have been established for blue crabs using wet weights, including the recent study by Olmi and Bishop (1983) and the studies of Newcombe et al. (1949), Tagatz (1965), Pullen and Trent (1970), and Diaz and Fredette (unpublished results). However, with the exception of Newcombe et al. these studies were principally concerned with adults and large juveniles. The purpose of this paper is to extend the size-weight relationships for C. sapidus to include juveniles less than 60 mm carapace width and to include dry
