Abstract

This study aimed to investigate the effects of dietary vitamin A and determine its requirement of juvenile red swamp crayfish (Procambarus clarkii). Six isonitrogenous, isolipidic, and isoenergetic experimental diets were formulated with analyzed vitamin A potencies of 11573 (A1), 20042 (A2), 26274 (A3), 37818 (A4), 55159 (A5), and 79200 (A6) IU/kg, respectively. These diets were fed to crayfish with an initial average body weight of (3.40±0.01) g for 8 weeks. The results revealed that weight gain rate and specific growth rate were significantly higher in groups A4 and A5 compared to the control group (A1) (P
