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.
