Description Although oyster culture dates back to First century
B.C., the development of hatchery techniques for the
production of oyster seed on a year round basis is
a recent innovation. Since early 1950s attempts for
large scale production of oyster seed have been initiated.
Loosanoff and Davis (1952), Dupuy et al. (1977)
and AQUACOP (1977) have successfully produced seed
of the oysters Ostrea edulis, Crassostrea virginica and
Crassostrea gigas. Nayar et al. (1984) have successfully
accomplished the production of seed of C. madrasensis
oh a large scale at the molluscan hatchery laboratory
of Central Marine Fisheries Research Institute
at Tuticorin. At this hatchery cultched as well as free
or cultchless spat are produced. The production of
oyster seed by hatchery techniques is accomplished in
six phases of operations viz., (1) Conditioning adult
oysters for maturation of gonads (2) Induced spawning
(3) Larval rearing (4) Culture of algal food (5) Preparation
of spat collectors and (6) Setting of spat. These
six functions although interrelated are independent
phases of operation and easy to follow and implement.
