| Abstract: | Water quality parameters in the water treatment facilities, the growth, immune enzymes and digestive enzymes of cultured Cynoglossus semilaevis Günther were determined in closed re-circulating aquaculture systems, as well as in flow culture systems. The result showed that, during a period of 25 days, water quality parameters in the bio-filter including ammonia-nitrogen, nitrite-nitrogen, phosphorus, COD and SS ,were significantly (P<0.05) lower than those in the culture bank, the average removal rates were 58.13%, 19.47%, 10.47%, 25.36%, 30.30%, respectively. The average removal rates of COD and SS by mechanic filter were 14.43%, 67.13%. Phosphorus, COD and SS by ozone-protein skimmer were 13.10%, 22.43%, 58.75%, respectively. The concentration of ammonia-nitrogen in the re-circulating aquaculture bank was significantly (P<0.01) lower than that in the flow culture bank. Cynoglossus semilaevis Günther grew at 2.85 g per day with a feed conversation ratio of 1.08 in re-circulating aquaculture systems, while in flow culture systems, it grew at 2.01 g per day with a feed conversation ratio of 1.33, they were significantly difference (P<0.05). The AKP, ACP, LSZ activity in blood serum of Cynoglossus semilaevis Günther were no significantly difference (P>0.05) between re-circulating aquaculture and flow culture, but amylase activity in stomach and intestinal of Cynoglossus semilaevis Günther in re-circulating aquaculture were significantly difference (P<0.01) higher than those in flow culture, proteaseactivity in stomach and trypsin activity in testinal were significantly difference (P<0.05) higher than those in flow culture. The predominance which was the higher efficiency of water qualities treatment and better effect of culture was demonstrated obviously in closed re-circulating aquaculture systems. |
