Seasonal changes in the depth distribution of bivalve larvae on the Southern New England Shelf
A limited survey was made of the seasonal change in occurrence, depth distribution, size distribution, and species composition of bivalve larvae at a single station on the southern New England shelf during the period April-December 1981. The data were related to temperature structure of the water co...
