Gametogenic Cycle Of Sea Scallops (Placopecten Magellanicus (Gmelin, 1791)) In The Mid-Atlantic Bight, A. C. Schmitzer, W. D. Dupaul, J. E. Kirkley

VIMS Articles

Gametogenesis of the sea scallop, Placopecten magellanicus , from 3 areas within the mid-Atlantic Bight was examined from January to December 1988. Histological and morphometric quantification of gonadal tissue concluded that a semiannual gametogenic cycle was characteristic of sea scallops from the mid-Atlantic Bight. The majority of spawning occurred in May and November. Gonadal development in spring comprised a longer period of time and resulted in greater fecundity than in fall. Differences were found in the timing and magnitude of the semiannual gametogenic processes between sex, area, and water depth within the study area. Varying temperature patterns between the mid-Atlantic …
