ABSTRACT
The Central Institute of Brackishwater Aquaculture has developed an indigenous hatchery technology for Asian seabass. The open sea cage culture has been expanding in recent years on a global basis and it is viewed by many stakeholders in the industry as the aquaculture system of the millennium. Cage culture has made possible the large-scale production of commercial finfish in many parts of the world and can be considered as the most efficient and economical way of rising fish. Similarly the nursery rearing is another step in the seed production particularly if it is for cage culture. Nursery rearing can be done as the primary steps in case of pond culture in the same culture conditions; whereas in cage culture it is entirely different, it requires comparatively larger seeds in for culture as the fish culture in cages were in different culture conditions of open water systems.
