Gonadal ascorbic acid and changes in level with ovarian development in the crucian carp, Carassius carassius (L.)

Ascorbic acid in the gonads of North Sea dab (Limanda limanda) during the reproductive cycle

“…The concentrations determined here in dab ovaries correspond to ascorbate concentrations in another marine fish species, Atlantic cod (Gadus morhua) (Sandnes and Braekkan 1981). Similar sexual differences but lower ascorbate concentrations were determined in crucian carp (Carassius carassius) by Seymour (1981) and in Arctic char (high-mountain charr) (Salvelinus alpinus) by Dabrowski (1991); both are freshwater species.…”

Reproductive Success of Female Rainbow Trout (Oncorhynchus Mykiss) in Response to Graded Dietary Ascorbyl Monophosphate Levels1

“…The fish in their experiment were fed high levels of ascorbic acid: 2000 mg/kg diet. Seymour [7], in contrast, found a steady increase of ascorbic acid in eggs throughout maturation in crucian carp. The maximum levels of ascorbic acid measured, however, were 200 p±g/ g eggs in crucian carp, whereas those measured in cod and trout and in the present study in rainbow trout reached approximately 500 pzg/g eggs.…”

Development of Brood-stock Diets for Nile tilapia Under Hapa-in-Pond Hatchery System; Optimal Dietary Vitamin C Level for the Optimum Reproductive Performance and Fry Survival

“…Elevation of Vitamin C content in female gonads during maturation and its transfer from brood fish to be stored in eggs for supporting larval growth and development until first feed intake was reported by [11,19,21] Mean ± SE values in each row followed by a common letter are not significantly (P ≤ 0.05) different Mean ± SE values in each row followed by a common letter are not significantly (P ≤ 0.05) different …”
