Grouper culture in brackishwater ponds

Abstract

Groupers (Epinephelus) are cultured in the Philippines using tiny fry and juveniles caught from the wild. A SEAFDEC/AQD technology verification study on grouper pond grow-out culture resulted in high productivity and profitability, indicating that grouper culture could become another income source for the country. This aquaculture extension manual is intended as a guide for fishfarmers and aquaculturists, extensionists, and students of aquaculture. It covers the following areas: What are groupers?; Commercially important groupers; Source of fry or fingerlings; Common collection gears for fry/juveniles; Brackishwater pond culture -- pond specifications, site selection, pond preparation, nursery operation, grow-out culture, harvest, post-harvest; Growth, survival and feed efficiency performance of grouper reared in brackishwater pond; Economics; Marketing and transport; and, Diseases.
