Abstract
    The effects of vitamin C (ascorbic acid -AA) and vitamin E (tocopherol) on the maternal performance and offspring quality of the freshwater prawn Macrobrachium rosenbergii were investigated. Three diets containing increasing levels of 2-ascorbyl-L-polyphosphate, and a fourth one containing comparatively higher alfa-tocopherol acetate (alfa-TA) levels, were fed to prawn females during 155 days. Higher dietary levels of AA and alfa-TA did not affect moulting, growth, or mortality rates of the broodstock. Also, breeding frequency and fecundity were not related to the dietary treatments. However, the contents of AA and alfa-tocopherol in the midgut gland, ovary , eggs, and newly hatched larvae increased along with higher dietary levels of these vitamins. The present results suggest that broodstock diets containing 60 µg AA.g-1 DW and 300 µg alfa-TA.g-1 DW are sufficient to ensure proper reproduction and offspring viability. However, feeding M. rosenbergii females higher dietary levels of both AA and alfa-TA (each around 900 µg.g-1 DW) might increase larval quality, as demonstrated in this study by the higher tolerance to the exposure to ammonia.
