The Effect of Increased Scale of Production on Fish Silage Quality

Dead fish due to reversal of water mass in floating net cages cultivation, most of which cannot be sold because they are not suitable for consumption or processing into food. One effort that can be done to increase the added value of dead fish is processed into silage. Silage is a very good feed ingredient for fish and poultry because of its low metabolic basal energy. This study aims to determine the effect of increasing the scale of production on the characteristics of fish silage quality. The research method used was experimental with a complete randomized design consisting of 3 treatments namely a) scale of production of 1 kg of fish, b) scale of production of 5 kg of fish, and c) scale of production of 25 kg of fish. The three treatments were repeated 3 times. The parameters observed were protein content, fat, ash content, water content and amino acid composition of silage fluid and rendemen. Data obtained from all observation variables except amino acid compositions were analyzed by F test, if significant continued with Duncan test, each test was carried out at 95% confidence level. The results of the study obtained conclusions that the quality characteristics of fish silage made from dead fish due to reversal of water mass were not affected by the scale of the production process. The silage quality characteristics produced in this study were protein content of 16.02%, fat content of 8.98%, ash content of 2.35%, carbohydrate content of 2.45% and moisture content of 70.2%. Rendemen is 62.72%
