Four-day-old fry of Clarias gariepinus (Burchell) were fed five types of feed for 28 days.
Survival of fry for each type of feed was 60% (Artemia only), 56.7% (Artemia + artificial feed),
50% (periphyton + artificial feed), 46.7% (periphyton only) and 40% (artificial feed only). Fry
fed Artemia only had a significantly higher growth in weight (p <0.05). Growth and survival in
fry fed the combination diets were comparable (p >0.05). The results indicate that periphyton
(fauna) can be used partially or wholly as an alternative to Artemia in fish larvae rearing.
