A COMPARISON OF LARVAL AND JUVENILE STAGES OF THE LOBSTERS Homarus americanus, Homarus gammarus, AND THEIR HYBRID 1
Abstract Previous studies have shown that H. gammarus progeny are generally larger than those of H. americanus at all stages (Gruffydd et al., 1975; Van Olst et al., 1976). In addition, the 2 nephropid lobsters are known to be similar genetically (Hedgecock et al., 1977). Recently these 2 closely re...
