Nursery rearing of seabass fry and importance of grading and seed transportation

The Asian seabass (Lates calcarifer) is an important food \nfish and a potential aquaculture species in tropical \ncountries. It exhibits catadromous habits within its areas \nof distribution. It is an advantageous culture species \nbecause after early larval rearing in seawater, it can be \ncultured in all levels of salinity, from fresh to seawater, \nand in a variety of culture systems from open ponds and \ncages to flow-through and closed recirculation systems. \nIn addition, this species produces large number of eggs \nthat can be reared intensively on fresh and pelleted feeds, \nand can reach a market size of 350 to 700 g in one year or \nless periods under optimum culture conditions.
