Abstract

lam size, sex of clam, concentration of serotonin, and site of administration of serotonin were found to influence the mduction of spawning in the hard clam Mercenaria mercenaria (Linne). Overall, male clams greater than 36.4 mm thickness were ~ore likely_ to spawn in response to ser~ton~n i_njection at concentrations of 0.2 or 2.0-mM. Administration of serotonin by injection m the antenor adductor muscle resulted m sJgmficantly more spawnings than intragonadal injection or dispersal in water surrounding the incurrent siphon.
