摘    要:在封闭循环水养殖条件下,半滑舌鳎(Cynoglossus semilaevis Günther)的平均养殖密度(15.07±0.22)kg/m3,观测半滑舌鳎的呼吸频率,检测养殖水体中溶氧、氨氮、亚硝酸氮等24 h内摄食和代谢的变化规律。结果表明:(1)半滑舌鳎摄食前、后的呼吸频率平均值分别为27.3次/min和34.7次/min,摄食后的呼吸频率显著高于摄食前;(2)投喂前、后2.5 h内,水中溶氧一直处于下降趋势,在摄食2.5 h后,水中溶氧处于稳定的上升趋势;(3)投喂后,氨氮、亚硝酸氮浓度显著增高,2.5 h后达到峰值,随后缓慢降低,在下次投喂前0.5 h达到最低值。说明半滑舌鳎摄食活动对循环水养殖水质的影响呈现规律性,也说明循环水养殖模式可以满足半滑舌鳎对水质的基本要求。

关 键 词:半滑舌鳎  循环水养殖  摄食  水质

Abstract:In order to collect more data base of intensive aquaculture of Cynoglossus semilaevis,in high density of the closed recirculating aquaculture system,Cynoglossus semilaevis’s breath rate were observed,and the changing of DO,NH3-N and NO-2-N in culturing water were also collected in the key times of a day when the fish’s feeding and metabolism changed.There were three results as follows:(1) The average breath rate of Cynoglossus semilaevis was 27.3 times/min before feeding and 34.7 times/min after feeding.It shows that the number of the fish’s breath rate ascend remarkably after they were feed;(2) The number of DO was in a dropping trend in the 2.5 hours before and after feeding,and in an rising trend 2.5 hours after feeding;(3) The numbers of NH3-N and NO-2-N in the culture water remarkably rise after breeding,and 2.5 hours later it touch an summit number.After that,the number drop down slowly to the lowest number until 0.5 hours before next feeding.The result showed that there were regulations of effect feeding to culture water,also show that recirculation aquaculture system meet the need of water quality.
Keywords:Cynoglossus semilaevis  recirculating aquaculture  feeding  water quality
