我国河沟资源丰富,发展养殖潜力很大。过去,大力发展河沟养殖困难较多,主要是养殖需投饵、施肥和养殖对象的排泄物影响饮用水卫生,加上运输船只较多,来往频繁,增加了围拦防逃的难度。近几年来,随着农村“改水”和“村村通公路”工程建设速度加快,农民不再饮用河水了,运输也由车运替代了船运,同时罱泥、捞水草积肥的减少,这些因素都给利用河沟养殖提供了有利条件。笔者认为发展河沟养殖生产必须抓好以下几个环节。
China’s river ditch is rich in resources and has great potential for development and culture. In the past, it was difficult to vigorously develop aquaculture in the river gully, mainly due to the need to feed the aquaculture products. The excrement of fertilizers and breeding objects affected the drinking water hygiene, coupled with the large number of transport vessels and frequent exchanges, which made it more and more difficult for them to escape and escape. In recent years, with the accelerated construction of “water diversion” and “village-through roads” in rural areas, peasants no longer drink river water, transport also replaces shipping by motor transport, and at the same time, All these factors provide favorable conditions for the utilization of river furrows. I believe that the development of aquaculture production must grasp the following aspects.
