Effects of Crude Extract from Capsicum spp. and Effective Microorganisms (EM) on Growth Performance of Hybrid Walking Catfish (Clarias gariepinus x Clarias macrocephalus)

Abstract

The aim of this research is to study the effects of crude extract from Capsicum spp. and EM on growth performance of hybrid walking catfish stocked 80 fish/1 m² of floating basket. The experiment design was completely randomized design and there were 4 food formula, 3 repeated; the food formula 1 consists of pelleted feed; the food formula 2 consists of pelleted feed and EM; the food formula 3 consists of pelleted feed and crude extract from Capsicum spp.; and the food formula 4 consists of pelleted feed and crude extract from Capsicum spp. and EM. The Experiment was performed at Mahasarakham College Agricultural and Technology for 122 days of duration. The results showed that the food formula 4 gave the highest average weight of hybrid walking catfish,  followed by the formula 3, the formula 2, and the formula 1 with 116.05 3.853, 107.191.889, 102.801.854, 91.2852.736 g, respectively. Moreover, the food formula 4 gave the highest average length of hybrid walking catfish, followed by the formula 3, the formula 2, and the formula 1 that the average length of hybrid walking catfish equals to 25.860.828, 25.110.813, 22.540.327, 22.250.656 cm, respectively with highly significant differences (p<0.01). The food formula 4 gave the highest average diary growth, followed by the formula 3, the formula 2, and the formula 1 that increased 0.86, 0.78, 0.75, 0.65 g/fish/day, respectively and the food formula 4 gave the highest survival rates, follow by the formula 3, the formula 2, and the formula 1 with to 89.05, 85.21, 79.33, 75.83 %, respectively at the highly significant differences (p<0.01).
