Abstract

The effect of Spirulina powder at levels of 0 (control), 3, 7, and 10%, of food ratio on growth, survival, and total carotenoids of dwarf gourami fry (Trichogasterlalius) of 3.6 g average weight as well as its larval stage was investigated for a period of 8 weeks. Carotenoids was significantly increased with increase in spirulina level up to 7% (p<0.05), but not significantly different from 10% level (p> 0.05). Survival showed no significant difference (p> 0.05). In larvae, survival, total carotenoids and total length increased significantly with increasing spirulina powder (p<0.05). Overall, the spirulina powder at 3% improved the growth and total carotenoids factors in pre-adult gourami and 10% level for larval stage as the best treatments in this study.
