Abstract: Brazilian fish farming has expanded due to the diversity of fish species with considerable potential for commercial production. One of the primary factors in fish nutrition in raising fish is dietary protein. However, fish do not specifically require crude protein but rather a balance of essential and non-essential amino acids. In this sense, methionine is an essential amino acid that must be provided in the fish diet because it synthesizes body protein. A deficiency of methionine plus cystine in the diet can cause reduced growth in fish. Most studies on dietary methionine plus cystine supplementation in fish have focused on growth and body nutrient deposition, with little information available on the effect of methionine plus cystine on hemato-biochemical parameters. The requirement of methionine plus cystine in fish diets to promote maximum growth ranges from 0.53 to 1.45%.
