Technology engineering of rearing red tilapia saline (oreochromis niloticus) fed on artificial diet enriched with protease enzymes in an eroded brackish water pond

Technology engineering of red tilapia saline (O niloticus) was reared in brackish water pond fed on artificial diet enriched with protease enzymes in an eroded brackish water pond. The purpose of this study was to know of technology engineering of red tilapia saline reared in brackish pond that is exposed to effect eroded brackish water pond and the effect of adding protease enzymes in artificial feed to accelerate the growth and survival of red tilapia saline fish. The fish samples in this study used red tilapia saline with and average weight of 1.25 ± 0.09 g / fish with stocking 10 fish / m2. This research used experimental method with Completely Randomized Design, 4 treatments and 3 replications. The treatments in this study were the addition of papain protease enzyme in the artificial feed with different dose ie A (0 mg / kg of feed), B (350 mg / kg of feed), C (700 mg / kg feed), D (1050 mg / kg feed ). The parameters to be determed include relative growth rate (RGR), feed utilization efficiency (EPP), protein efficiency ratio (PER), feed conversion ratio (FCR), survival rate (SR), and water quality.
