Abstract
Giant freshwater prawn Macrobrachium rosenbergii is a fisheries local commodity that is quite promising in terms of economy. However, its culture is constrained by expensive feed prices so it needs to be overcome through the use of feed based on local raw materials. However, the utilization of feed based on local raw materials cannot be done optimally because it often contains limiting factors such as crude fiber, tannins, and so on. Therefore the application of fermentation is expected to overcome this problem. This study aims to evaluate the use of fermentation in feed based on local raw materials and its effect on the growth performance of giant freshwater prawn (Macrobrachium rossenbergii). The study was conducted using a completely randomized design with 3 treatments and 3 replication. The treatments carried out in this study were as follows: Treatment A was commercial feed, Treatment B was feed based on local raw materials and Treatment C was feed based on local raw materials that fermented using Bacillus subtilis TS2b. Parameters that measured include absolute and relative weight growth, specific growth rate, survival rate, feed efficiency, protein and fat retention. The results showed that fermented local raw material-based feed using Bacillus subtilis TS2b could potentially be used for the growth of giant freshwater prawn.
