Larval sea scallops (Placopecten magellanicus) were reared in the laboratory and their shell growth lines were Counted and used to estimate age in days. The first growth line was deposited 3 to 4 days after fertilization. Age estimates from growth-line counts were strongly correlated with the actual ages of the larvae. Photoperiod had no detectable effect on the rate of growth-line deposition.
