Effects of dietary protein to energy ratios on growth and body composition of juvenile Chinese sucker,Myxocyprinus asiaticus

A growth experiment was conducted to investigate effect of dietary protein to energy ratios on growth and body composition of juvenile Myxocyprinus asiaticus (initial mean weight: 10.04 ± 0.53 g, mean ± SD). Nine practical diets were formulated to contain three protein levels (340, 390 and 440 g kg−1), each with three lipid levels (60, 100 and 140 g kg−1), in order to produce a range of P/E ratios (from 22.4 to 32.8 mg protein kJ−1). Each diet...
