池塘分区集群式清洁养殖新模式的概念、原理与方法

摘要

The concept, principle and methods of a new culture model-partition cluster clean culture in ponds ( PCCP) were discussed. Partition cluster clean culture in ponds is a new pond culture model of which is different from traditional polyculture in a pond. In condition of health culture, artificial feeding fishes were cultured in small scale zone names as high density fish culture zone in a pond. Fish fecal zone named as sewerage district were con-trolled to remove fecal timely, and the aim was to reducing residual feed and fish feces of which were discharged in-to sewage treatment zone outside the pond, to avoid water pollution and oxygen consumption. While changing most of the water areas in the pond is a water purification zone. And through the practice example of the kind of culture model, the existing problems and development prospects were also discussed. The results indicated that the features of this new pond culture model were three partitions of high density fish culture zone, sewerage district and water purification zone within the pond, in the model cultured fishes clusters, precise feeding, and remove fecal and rem-nant timely were carried out. Fish production is higher than that in traditional pond culture models, and achieves the purpose of saving water and reducing discharge.%对一种新的养殖模式———池塘分区集群式清洁养殖的概念、原理与方法进行了论述。池塘分区集群式清洁养殖( partition cluster clean aquaculture in ponds, PCCA)模式是一种不同于传统混养的池塘养殖新模式,即在健康养殖条件下将人工投喂的鱼类集群圈养于池塘小范围区域(即集群养殖区)中,通过控制鱼类粪便的排泄区域(沉淀排污区),做到及时将粪便清除到池塘外污水处理区,以降低鱼类粪便、残饵等对水体的污染及溶解氧消耗,使池塘中大部分水体区转变为水质净化区域,并通过该种养殖模式的实例,对其存在的问题和开发前景进行了讨论。研究表明,采用池塘内分区、养殖鱼类集群、精确投饵和及时清除粪便及残饵的池塘清洁养殖新模式,产量高于传统养殖模式,可达到节水减排的目的。
