From Abstract: In this study, researchers looked at the inclusion of chitosan in tiger shrimp (Penaeus monodon) diets. They concluded: “All results suggested that dietary intake containing 0.1% and 0.2% chitosan enhanced the growth of shrimp, whereas a higher level than 0.3% and 0.4% decreased growth of shrimp. Second-degree polynomial regression analysis of weight gain and biomass gain indicated that the optimum supplement of dietary chitosan level should be 0.19–0.21%.”
