Ascorbic acid requirement in freshwater and marine fish. Is there a difference?

ByMarie F. Gouillou-Coustans, Sadasivam J. Kaushik

In this general context, an attempt was made to verify whether vitamin supplementation at the minimal requirement level as defined by the NRC4 is sufficient for two freshwater species such as rainbow trout and chinook salmon, O. tschawytscha, and two marine species, European sea bass, Dicentrarchus labrax, or red drum, Sciaenops ocellatus, fed practical diets.8, 9 The results demonstrate that supply of all vitamins at their minimal requirement levels is sufficient to support rapid and maximal weight gain for diverse species of freshwater or marine finfish, namely trout and chinook salmon juveniles, European seabass or red drum were fed diets with practical ingredients (Table 6.2).
