Abstract:

Juvenile spotted babylon (Babylonia areolata) and sea bass (Lates calcarifer) were cultured in 11.5-m³ indoor rearing tanks supplied with flow-through of ambient natural sea water over a 120-day experiment. Each species, stocked at the following  densities for the following treatments, was tested with three replicates per treatment: 5000 B. areolata per tank (Treatment 1); 200 L. calcalifer per tank (Treatment 2): and 5000 B. areolata plus 200 L. calcalifer per tank (Treatment 3). The average growth (length and weight), feed conversion ratio and total production of spotted babylon and sea bass from Treatment 3 were not significantly different from those of Treatment 1 and 2 (P>0.05). Average survival rates for both spotted babylon and sea bass exceeded 95% for all treatments.
