AB -  and The volume of the eggs produced by crustacean species is, in part, under genetic control (Raven, 1961). It shows a general pattern of interspecific variation, decreasing from colder to warmer waters over a north- south latitudinal gradient, and from deep- sea benthic to shallow coastal and epipelag- ic waters (e.g., Omori, 1974; Sastry, 1983). In fresh-water decapods, large eggs appear to be associated with landlocked species in- habitating plankton-poor, clear, and rather acid waters, and small eggs mostly to anad- romous and brackish species (Shokita, 1979; Magalhaes and Walker, 1988; Odi- netz Collart and Magalhaes, 1994; Jalihal et al., 1993). The same continentalization pat- tern has been described in Macrobrachium nipponense (de Haan), where large eggs were found in fresh-water lake and river populations, small eggs in estuary popula- tions, and intermediate-sized eggs in brack- ish-water populations. At times, the full size range is seen in a single water system (Chow et al., 1988; Mashiko, 1990). Cross- ing experiments between individuals of M. nipponense from two adjacent groups of a single drainage system suggested that the egg-size differences among local, ecologi- cally isolated populations are controlled as a quantitative genetic trait (Mashiko, 1992; Mashiko and Numachi, 1993).
