Abstract

This paper presents the protocols standardized for producing triploid edible oyster, Crassostrea madrasensis by retention of I1 polar body (MI1 triploids), using physical (heat and cold shocks) and chemical agents (Cytochalasin B and 6-Dimethylaminopurine), as well as the protocol for preparation of metaphase spreads for cytological confirmation of triploidy and estimation of its percentage. Among the four inducing agents tried, 6-Dimethylaminopurine yielded highest percentage of triploids (66.6 in day old and 61.82 in "D" stage larvae).
