Effect of tomato (Solanum sp.) as feed additeve on growth, survival and pigmentatition of angelfish (Pterophyllum scalare)

Abstract

This study was conducted to determine the effect of survival, specific growth rate (SGR), and pigmentation of Angelfish fry (Pterophyllum sea/are) feed with different levels of tomato. Different levels of tomato as the feed additive were apportioned for diet 1, diet 2, diet 3 and diet 4.Diet 1 as a control contained 98% pellet and 2% of wheat flour, diet 2 contained 88% pellet, 10% tomatoes, and 2% of wheat flour, diet 3 contained 78% pellet, 20% tomatoes and 2% of wheat flour), and finally diet 4 contained 68% pellet, 30% tomatoes and 2% of wheat flour. Diet 1 and Diet 3 showed the best length ( 6.20±0.17),of Freshwater Angelfish (Pterophyllum sea/are), followed by diet 4 (6.03±0.23) and diet 2 (5.90±0.10). Freshwater Angelfish, Pterophyllum sea/are with diet 1 showed the best mean weight (5.15±0.19), followed by diet 3 (3.65±0.33), diet 4 (4.63±0.46) and diet 2 (4.17±0.48) respectively. However, mean length and weight of Freshwater Angelfish, Pterophyllum sea/are was not significantly different (P>0.05) between the treatments (level of tomato).
