Abstract

 To improve the quality of brackish water bivalve Corbicula japonica by rearing in a short period, we examined the effect of various carbohydrates on the increment of glycogen content and the comparison of palatable amino acids uptake under hyperosmotic stress. As a result, rice powder was effective for increasing glycogen content at 0.1 g/L concentration, suggesting that insoluble carbohydrate was suitable for this purpose. When reared in 2 mM alanine, glycine, glutamic acid or proline accompanied with transferring from 0.5% to 1% salinity for 24 h, glycine was most effectively absorbed, followed by proline, alanine and glutamic acid. In conclusion, the quality of euryhaline bivalve C. japonica could be improved in a short period by feeding rice powder and rearing in palatable amino acids accompanied with osmotic stress.
