Utilization of fermented Seligi leaf flour Phyllanthus buxifolius toward the specific growth rate, daily growth rate and survival rate of siam catfish (Pangasius pangasius)

Siam Catfish (Pangasius pangasius) is a freshwater fish commodity that has important economic value because of its fast growth and easily cultured. One way to increase catfish production is through fulfilling the nutritional requirements through the feed. However, the problem that often arises is the high cost of feed, so it is necessary to use the alternative feed to reduce feed costs. Seligi leaf flour (Phyllanthus buxifolius) is an alternative feed material that can be used as additional feed ingredients. But Seligi leaf flour has a high crude fibre content of 15.48% while the crude protein is 11.53%. Fermentation is needed to reduce crude fibre and increase protein. Specific growth rate, daily growth rate and survival rate are factors that need to be considered in the process of fish culture. The results of this study indicated that the use of Seligi leaf flour (Phyllanthus buxifolius) in catfish showed no significant difference (P> 0.05) with the control treatment at specific growth rates, daily growth rates, and survival of siam catfish (Pangasius pangasius).
