摘要:

以三峡童庄河库湾不投饵养殖模式和湖北公安养殖池塘中肥水养殖模式下的三角帆蚌为对象,研究了不同放养模式对三角帆蚌生长及养殖产量的影响,同时测定不同养殖模式下三角帆蚌体内和水体中TN、TP,分析三角帆蚌组织中TN、TP与不同水质环境下TN、TP的关系。结果表明:水体中N、P的水平对三角帆蚌的生长具有一定的影响;不同TN、TP水质条件下,三角帆蚌组织中的TN、TP没有差异,表明三角帆蚌组织中的TN、TP与水环境中的TN、TP没有相关性;传统肥水养殖模式下三角帆蚌的生长和产量都优于三峡童庄河库湾不投饵养殖模式,不投饵养殖模式珍珠的产能接近池塘传统养殖模式的下线。研究同时表明在大水面水体采取低密度吊样三角帆蚌的放养模式,在增加经济效益的同时,还可以充分利用水体中的初级生产力。这为控制水体的富营养化提供新的思路。

Abstract:

To examine the effect of cultured models on growth and yield of freshwater pearl mussel, an enclosure experiment was carried out in Tongzhuanghe River. a natural water- body,in the Three Gorge Reservoir Region and in the aquiculture ponds Gongan Country,Hubei Province. At the start and end of the enclosure experiment, shell length, total weight of the pearl mussel was measured. The quality indexes TN, TP of the water body and Hyriopsis cumingii tissue was analyzed. The results showed that The quality indexes TN , TP of the water body had certain influence to the Hyriopsis cumingii growth,In the Hyriopsis cumingii tissue's TN, TP and in water environment's TN, TP didn't have the relevance. Used low density cultivation models cultured pearl in big water surface not only increases the economic efficiency, but also may use the primary productive forces in the water body fully.
