Absorption of dissolved ascorbate by live channel catfish(Ictalurus punctatus)

live channel catfish were exposed to 0.3 % sodium ascorbate solution at pH5. Ascorbic acid concentration in the fillets was found to increase from 13ppm. initially (control group) to 51 ppm and 43 ppm for fish exposed to ascorbate for 8 Curd 24 h, respectively. For the group offish exposed to 8 h o...
