Sažetak
The determination of the optimum time and environmental conditions for initial feeding of sea bass larvae will contribute to the feasibility of their profitable culturing. Survival and growth of larvae were increased when ambient salinity (38‰) was reduced (10‰ and 20‰). Intermediate salinity (26‰) produced consistently better growth. Although increased temperatures (18 and 21°C) improved growth rates, survival was decreased below that at ambient (15°C). Feeding of cultured sea bass larvae has commonly begun at initiation of mouth opening (4 days after hatching). At reduced salinity (13‰ and 26‰) delaying initial feeding until the fifth day resulted in survival equal to that of those fed on the first day after mouth opening. Initial feeding can be delayed 2–4 days without adversely affecting survival or growth of sea bass larvae if they are held at ambient temperature in dilute sea water.
