Culture of Larval Seabass, Lates calcarifer (Bloch) in Saltwater Rearing Ponds in Queensland, Australia

Abstract:

Larval seabass (Lates calcarifer) were stocked into a saltwater rearing pond 48 hours after they had hatched. The pond had been fertilized with a combination of organic and inorganic fertilizers using techniques developed for saltwater hatchery ponds in Texas. Approximately 63,000 fingerlings were harvested from two trials after 25 and 22 days growth in the pond, respectively. Mean total length was 38.8 and 35.5 mm for the two trials, representing growth rates of 1.6 and 1.4 mm per day, respectively. Pond management and fertilization techniques used on saltwater hatchery ponds in subtropical Texas were applicable to conditions in tropical Queensland. These techniques can be used to produce large numbers of sea bass fingerlings for aquaculture and to enhance sea bass populations in recreational fisheries.
