| The effect of vitamin C on mortality rate was sharp decreased when fish fed containing 250 mg vitamin C kg diet were high mortality rate reached to 70 % for common carp and 50 % for grass carp when fish fed zero mg vitamins. C kg diet while the rate decrease when fish fed 50 mg vitamin C kg diet reached to 60 % and 40% for two species respectively in the end of experiment after 24 weeks in significant (P<0.05). Scales fall down was increased significant for two species in vitamin C concentrations in fish fed (zero and 50) mg vitamin C kg diet, they were in the end of experiment (18.2 ± 0.20, 11.8 ± 0.20) and (23 ± 0.31, 15.1 ± 0.20) for both species respectively. | ||
