Hatchery development for shellfish seed production

Abstract

The evolving of hatchery techniques for producing seed of marine molluscs of economic importance is one of the important achievements in marine fishery research in this century. This field of research had its origin in the efforts of a scientists who attempted towards the close of the last century and the early period of the twentieth century. Some of the earliest work in the subject is that of Brooks (1880) on the eggs and early larval stages of the American oyster Crassostrea virginica and the attempts by Ryder (1883) and Winslow (1 884) to grow oyster larvae to metamorphosis.
