Abstract
Description
The vertical and horizontal distribution of sea scallop larvae Placopecten magellanicus was studied. Scallop larvae can undertake diel vertical migrations in some parts of their range but since the migration is diel and of small amplitude ($$230 $\mu$m in length) larvae from Georges Bank. These measurements suggest that for large larvae: (i) starvation is rare; (ii) lipid levels are comparable to those of well-fed larvae; and (iii) condition may at times be more a function of physical stratification than of food concentration.
A coarse estimate of the annual production of late stage larvae (120-1500 m$\sp{-2}$) on Georges Bank suggests that considerable mortality is associated with metamorphosis, settlement, and the early juvenile period.
