“…Administration of hormones 17α-methyltestosterone and temperature variations is able to make the conversion value of feed on juvenile freshwater crayfish to be efficient. As a comparison, tilapia treated with 17α-methyltestosterone and temperature were able to give feed conversion ratio of 2.48 [32].…”
