Effect of Dietary Compound Acidifiers Supplementation on Growth Performance, Serum Biochemical Parameters, and Body Composition of Juvenile American Eel (Anguilla rostrata)

As growth-promoting feed additives, compound acidifiers (CAs) have been widely reported in many farmed fish species, whereas there is little information on the application of CAs eel diet. The present trial was conducted to evaluate supplementation effects growth performance, serum biochemical parameters, and body composition juvenile American (Anguilla rostrata). levels diet were 0, 2.0, 3.0, 4.0, 5.0 g/kg, respectively. lasted for 12 weeks. most beneficial promoting decreasing lipid, modifying parameters liver function immune serum, increasing utilization calcium phosphorus observed fed with 4.0 g/kg CAs. Dietary had no significant whole fish, dietary exerted negative phosphorus. recommended level 3.5–3.7 achieve optimal weight gain conversion ratio eel.
