Bay scallops, Argopecten irradians (Lamarck), from populations with low rib number (Texas) and high rib number (Virginia) were bred separately and also hybridized. The results suggest that rib number is under genetic control and that the two populations are genetically differentiated. Scallops taken from a population polymorphic for shell color (Massachusetts) were bred in groups, each group containing a single color. The results suggest that color is also under genetic control and is not strongly influenced by the environment

Thermal tolerance was tested in cleavage stages, trochophores and straight hinge larvae of the bay scallop Argopecten irradians. Experiments were designed to simulate larval entrainment in power plant cooling systems. An 11 (temperature) x 8 (time) matrix was used with temperatures ranging from 20.6 to 43.0 oc and exposure times from 1 min to 6 h. Pooled mortality data from triplicate experiments for each larval stage were subjected to stepwise regression analysis (Yarcsine % mortality on temperature and time). Equations derived from these analyses, comprising first, second and third order terms for temperature and time, were used to generate response …
