Effects of different dietary protein‐energy ratios on growth, carcass amino acid and fatty acid profile of male and female Cherax quadricarinatus (von Martens, 1868) pre‐adults

Cherax quadricarinatus or redclaw is considered a good option for freshwater aquaculture and has been cultivated in several countries. However, nutritional studies are scarce. In present research, the effects of different protein‐energy (P/E) ratios in diets for male and female of pre‐adults were investigated. Its influence on growth performance, carcass amino acid and fatty acid profiles were determined. Six different dietary P/E ratios: 12, 13, 14, 15, 16, and 17 mg of crude protein (CP) kJ−1 g−1 of food for 70 days were tested on male and female pre‐adults (initial weight 10.8 ± 0.6 g). The experimental treatments were assigned in triplicate. The significantly highest (p
