When surf clams have completed spawning (stage four, spent phase) and almost all mature gametes have been expelled, leaving nearly empty, shrunken, and lower-mass gonad, numerous serotonin-containing fibers encircle the acini, as also reported for the scallop Placopecten magellanicus of the same gonadal stage (Croll et al., 1995).
This may be partly due to the great variations in serotonin concentrations between individual specimens and the small sample size for the fourth phase (spent phase) of the gametogenic cycle.
