Developing technologies for giant grouper (Epinephelus lanceolatus) aquaculture in Vietnam, the Philippines and Australia

This project aims to build the foundation skills and knowledge for establishing sustainable hatchery production of giant grouper in the Philippines, Vietnam and Australia.
Groupers form the basis of the live reef food-fish trade in the south-east Asian region. Due to considerable pressure on wild populations, it is already difficult to source wild-caught giant grouper in some countries. The giant grouper, Epinephelus lanceolatus, is a high-value, fast-growing grouper species with significant aquaculture potential.
The Philippines and Vietnam are considering farming giant grouper to compensate for the declining catch from the wild and to meet market demand. They have not commercially produced juveniles, because they lack knowledge on the species' maturation and spawning behaviour, and few larvae survive. Giant grouper males are also used to create desirable hybrids with tiger groupers.
The project is developing reliable captive-breeding technologies to close the life cycle, including exploring the potential of genetics and biotechnology to control reproduction.
Activities will build capacity in all aspects of sustainable giant grouper aquaculture, and benefit aquaculture farmers. The research is expected to enable initiation of a giant grouper industry in Vietnam, the Philippines and Australia.
