The Asian seabass Lates calcarifer (Bloch) is widely distributed in the IndoWest Pacifi c. Because of its high commercial value, it is widely cultured in most of Asia and Australia. However, seed supply from the wild is not abundant; hence the aquaculture of seabass is based on mass seed production in hatcheries. Seabass spawn naturally in captivity (Toledo et al. 1991). Alternatively, they can be induced to spawn by hormonal or environmental manipulations (Kungvankij 1987, Garcia 1989a, b). The development of methods for broodstock management for reliable reproduction of seabass under captive conditions paved the way for studies on the environmental, physiological and nutritional requirements of the developing larvae and the development of protocols for seed production in the hatchery (e.g., Parazo et al. 1998, Schipp et al. 2007).
