Abstract

This experiment was carried out to evaluate the effect of earthworm (Eisenia fetida) in diet for Oscar fish (Astronotus ocellatus) in a randomized design with three treatments in triplicates using 9 aquarium for 9 weeks. Twenty pieces of Oscar fish with average weight 3. 6± 0. 5 g were stocked in each replication. The Earthworm meal (as fed) at the levels of 0, 50 and 100% was replaced with Biomar diet in Oscar fish diet. Fish were fed with experiential diets included: 1-Biomar 2-Mixture of Biomar and Earthworm meal with equal ratio 3-Earthworm meal. Daily food intake calculated by the weight of fish (3% of body weight) and fish were fed 3 times a day. Physical and chemical properties of water, such as temperature (28. 2 C± 0. 5), oxygen (7. 8ppm± 0. 2) and pH (8. 1± 0. 11), were control. At the end of study Growth performance, feed utility and Survival rates were measured. The highest body weight increase (173. 2% (gr)± 0. 23), specific growth rate (2. 02 (%)± 0. 26), average daily growth (17. 4 (%)± 3. 15), protein efficiency ratio (1. 85 (%)± 0. 16) and least feed conversion ratio (0. 99 (%)± 0. 05) observed in Biomar treatment (p<0. 05). But greatest Survival ratio observed in diet contained earthworm powder. The results assessment showed that neither 50% nor 100% worm meal could not supply Oscar fish nutritional requirements.
