The growth and mortality of olive flounders fed with chitosan-coated or
non-coated MP diets were evaluated for 12 weeks and weighed every
2weeks. The average growth of the chitosan-coated diet group increased by
approximately 10%, as compared to that of the control fish group (Fig. 1).
In addition, accumulation of mortality was reduced in the fish fed with the
chitosan-coated diet as compared with the non-coated diet group (Fig. 2).
These results might be induced froman improved fish tank environment, as
shown by the decreased COD and SS levels, and enhanced non-specific
immune response by chitosan.
