摘要：

The survival of grass carp juveniles overwintered in ponds and RAS were compared in this study. The grass carp, W = 2.49 +/- 0.34g, were distributed among five 350 L tanks connected to a RAS and/or into three (1500 m(2)) ponds (P group). After 165 days, the survival rate was significantly higher in the RAS group, 97.8 +/- 0.5%, compared to 10.9 +/- 11.4% in P group. The grass carp in a RAS during the first winter significantly improved survival and good conditions of juvenile for subsequent ongrowing period. The RAS provided production profit compare to loss in P group.
