| Abstract | ||
| Long growing period and food price are a One of the major challenges in sturgeon. Sturgeon need 40 to 45% of protein during the growth period, that 50 to 60% is supplied by fish meal. There are two ways to reduce the cost of food. first way is to improving protein efficiency to fish increase growth by substances such as fats and carbohydrates as energy sources at certain levels, and second way is replacing fish meal ssubstitute with cheaper plant protein sources. However, lipid supplementation to diet and plant protein sources cause lipid deposition in body, carcasses reduce quality and fatty liver, such that fish can’t use this energy sources. L-Carnitine is one of the supplements that has been considered in recent years in aquaculture industry to improve food quality to fish increase growth via Accelerate lipid metabolism as an active transporter and lipid oxidation increase and protein sparing, ultimately producing low-fat, high-quality meat and improving fish growth. Investigation at the Sturgeon Research Institute have shown that supplementation L-carnitine at a dose of 600 mg/kg to sturgeon diet in plumb phase led to growth increases, carcass quality improving, 5% protein sparing and 10 % reduces food costs. | ||
