| The objective of this work was to evaluate the biologic and economic effects of chemical fish silage as a unique animal protein source. Ensiled Opisthonema oglinum with three combinations of organic and inorganic acids: 3 % of formic acid; 2 % sulfuric acid 98 % and 2 % formic acid and other with 2,6 % phosphoric acid; 2,6 % of citric acid and 0,1 % of sodium benzoate. From each silage a moist diet was prepared and was compared with commercial food (20 % of fish meal) in Clarias gariepinus feeding during 60 days. There were not significant differences (p > 0,05), in growth, feed utilization and survival indicators. The economic analysis showed a fingerling production cost saves between 20 and 30 % for feeding concept. |
