ABSTRACT
Five day old Helostoma temmincki larvae measing 4.6 ± 0.1 mm in total length were stocked into 12 larval culture tanks at the rate of 1000 larvae/tank (l0 larvae/l). The larvae were fed:
Diet I = (Egg yolk),
Diet II = (Egg yolk + Artemia naupliz),
Diet III = (Egg yolk + Microworms), and
Diet IV= (Egg yolk + Moina)foriz period of4 weeks.
Diet I = (Egg yolk),
Diet II = (Egg yolk + Artemia naupliz),
Diet III = (Egg yolk + Microworms), and
Diet IV= (Egg yolk + Moina)foriz period of4 weeks.
After 1 week ofrearing, larvaefed Diet III measun'ng 8. 4 mm total length and 7.0 mg weight were larger than larvae fed the other diets (P < 0.05).
At the end of 2 weeks, larvae fed Diets III, II and IV were larger than larvae fed Diet I (P <0.05).
From week 3 onwards, larvae fed Diet IV were consistently larger (P <0.05).
This experiment shows that microworms were very suitable as a starter feed, and that Moina was suitable for feeding Helostoma temmincki larvae after week 2 undertropical conditions.
At the end of 2 weeks, larvae fed Diets III, II and IV were larger than larvae fed Diet I (P <0.05).
From week 3 onwards, larvae fed Diet IV were consistently larger (P <0.05).
