Abstract
Larvae of Australian bass (Macquaria novemaculeata) were offered various concentrations of rotifers (Brachionus plicatilis) at 0-24 organisms/mL for 2 weeks starting at completion of yolk absorption. In another experiment, larvae initially fed rotifers for 2 weeks were offered brine shrimp (Artemia salina) at concentrations of 0-15 nauplii/mL. In each experiment the concentration of zooplankton had a significant (P < 0.01) effect on larval survival. The minimum concentrations that resulted in high survival and growth rates of larvae were 9 rotifers/mL for the first 2 weeks after yolk absorption and 6 brine shrimp nauplii/mL for the next 2 weeks.Keywords
