Abstract

Decades ago, breeding of Catfishes in captivity has been commonly practiced in the field of aquaculture industry due to their superb environmental adaptability in nature, but yet, there is still lacking of adequate information in Malaysia on the daily intakes and nutritional requirements that affects the survival and growth performance. Hence, this research was conducted to study on the growth, survival and deformities of African Catfish larvae with different types of feeds, which could be basically categorized into live feeds and artificial diets. In this paper, live feeds in preference were Moina and Artemia whereas the artificial diets were made up of Tilapia Starter Feed and also hatchery-made artificial compound feed. The feeding experiment was carried out in the UMS hatchery for a rearing period of 20 days using the 180 tails newly-hatched larvae for each selected feeds in three replications. All the newly-hatched larvae were given the first feeding equally on the 2 dAH onwards in morning, afternoon and evening till satiation. The results of growth and survival had shown that the larval fish fed with live feeds has a significant (P<0.05) difference over the fish fed with artificial diets where Moina feeders remained higher than the Artemia feeders at 20 dAH. On the other hand, Artemia feeders had the highest survival rate of 82.96% but poorer growth rate as compared to the feeders of Moina where the total mean body length ( cm) has achieved 1.50 ± 0.098 at the age of 20 dAH. However, the deformities study on these larvae didn't show much difference from the effects of the four feeding materials being used here.
