Abstract
A feeding trial was performed to determine the effects of three concentrations of vitamin A (VA, 5, 10, and 20 mg) on the survival and larval development of the cinnamon freshwater prawn Macrobrachium acanthurus. Microcapsules with the respective concentrations of the vitamins were prepared and used to enrich Artemia nauplii and fed twice daily to triplicate groups of 20 larvae at stage 3. Survival and stage of development were registered daily to produce survival curves and index of development. Results show that including 10 mg of VA improved the survival and development of larvae, while 20 mg caused high mortality and slower development after stage 6. The present results indicate that VA is necessary for M. acanthurus larvae, and its use may aid in overcoming the bottleneck associated with the larval rearing stage, thus promoting continued culture supplementation of this species.
