由于采用了淡水网箱养鱼和人工配合饲料等新技术,近年来海南省水库养色发展很快,水库网箱养鱼年总产量已达2700余吨。水库网箱养殖罗非鱼,属高产优质高效益农业项目。不仅鱼质好,群众欢迎,市场兴旺,而且单产高,亩产高达5万公斤以上,经济效益显著,发展迅猛。但同时也存在着品种退化、鱼病四起和养殖环境恶化、市场逐渐饱和等问题。为了加速发展淡水网箱养鱼,针对当前存在的主要问题,提出几项对策:
Due to the adoption of new technologies such as freshwater cages for fish farming and artificial feed, the reservoir color development in Hainan Province has developed rapidly in recent years. The total annual output of fish in the aquaculture cage has reached more than 2,700 tons. Tilapia aquaculture cage, is a high yield high quality and efficiency of agricultural projects. Not only the quality of fish is good, the masses are welcome, the market is prosperous, and the high yield per mu is as high as 50,000 kilograms per mu, with remarkable economic benefits and rapid development. At the same time, however, there are also problems such as the degeneration of species, the four fish diseases and the deterioration of the breeding environment, and the gradual saturation of markets. In order to speed up the development of freshwater caged fish farming, a few countermeasures are put forward in response to the main existing problems:
