“…In red drum, liver storage of ascorbic acid in response to graded levels of dietary vitamin C was not as readily influenced as seen in other species such as channel catfish ( El Naggar & Lovell 1991). However, levels of total ascorbate in livers of red drum fed diets with supplemental vitamin C were generally similar to those reported for some other fish species ( Bai & Gatlin 1992; Halver & Hardy 1994; Matusiewicz & Dabrowski 1996).…”

A feeding trial was conducted to determine the minimum dietary vitamin C requirement of juvenile red drum and characterize signs of vitamin C de®ciency. Semipuri®ed diets containing 400 g crude protein kg ±1 from lyophilized red drum muscle and crystalline amino acids were used in the feeding trial. The basal diet without supplemental vitamin C contained » 6 mg vitamin C kg ±1 and was fed for a 1-week conditioning period. Red drum, initially averaging » 3.6 g each, were fed diets supplemented with 0, 10, 20, 30, 45, 60, 75, or 150 mg vitamin C kg ±1 as ascorbate polyphosphate for a period of 10 weeks. Fish fed the basal diet began to exhibit overt signs of vitamin C de®ciency, including reduced weight gain, lordosis, scoliosis and loss of equilibrium after 8 weeks. Total ascorbate was undetectable in liver of ®sh fed the basal diet while liver ascorbate levels in ®sh fed the other diets generally re¯ected dietary supplementation. Regression analysis of weight gain data using the broken-line model resulted in a minimum vitamin C requirement (SE) of 15 3 mg kg ±1 diet.

“…Liver ascorbate in hybrid striped bass fed the basal diet was similar to that reported for channel catfish (Bai and Gatlin 1992). Atlantic salmon Salmo salar (Halver and Hardy 1994) and rainbow trout Oncorhynchus mykiss (Matusiewicz and Dabrowski 1996). Results from the present study suggest that liver storage of ascorbic acid in response to graded levels of dietary vitamin C was not as readily influenced as seen in other species such as channel catfish (El Naggar and Lovell 1991).…”

A feeding trial was conducted to determine the dietary vitamin C requirement of juvenile hybrid striped bass Morone chrysops × M. saxatilis. Fish were fed a semi‐purified basal diet with 40% crude protein and an energy to protein ratio of 8 kcal/g for a conditioning period of 2 wk. This diet which was not supplemented with vitamin C contained approximately 6‐mg vitamin C/kg. Following conditioning, fish (approximately 0.55 g initial weight) were stocked as groups of 20 in 38‐L aquaria and fed the basal diet and experimental diets supplemented with 10, 20, 30, 45, 60, 75, or 150‐mg vitamin C/kg as ascorbate polyphosphate for a period of 10 wk. Fish fed the basal diet and the diet supplemented with 10‐mg vitamin C/kg exhibited signs of vitamin C deficiency including suppressed weight gain, reduced plasma and liver ascorbic acid levels, and abnormalities in isthmus cartilage formation. Plasma and liver ascorbic acid levels generally reflected dietary supplementation with the lowest levels occurring in fish fed the basal diet and higher levels in fish fed the supplemented diets. The minimum dietary requirement (±SE) based on non‐linear least squares regression analysis of weight gain was 22 (±6) mg vitamin C/kg diet.
