Holding and spawning of the edible oyster Crassostrea madrasensis during off season

Abstract

Production of seed from the hatchery throughout the year would help to undertake stocking in the grow out systems at appropriate time which may vary in different areas. Ripe oysters with a size range of 70-120 mm were collected from Korampallam creek near Tuticorin. Thus holding the ripe oysters is a promising line of work for getting spawn in the hatchery outside the spawning period, leading to seed production throughout the year.
