洪湖在江汉平原南部,靠近长江,现有水面335平方公里,是湖北省最大的湖泊。1982年,由省、地和洪湖、监利两县的科技人员组成一个调查组,对洪湖的鱼类、底栖动物、微生物、水生植物、水文、气象等生物资源和非生物环境资源进行了一年的综合调查。调查后,开展了河蟹养殖、围网养鱼、种植家菱等小区试验,都取很了较好的经济效益。但目前洪湖渔业的总产值还不高,年收入只有500万元左右。为了进一步提高洪湖的生产效益,提出以下四个开发利用的方式。 1.发展河蟹养殖 据调查,洪湖内年产底栖动物49000吨、小虾2000吨和水草腐植质157万吨,这些都是河蟹育肥的好饲料。生产实践证明,养殖河蟹见效快,收入高。1981年洪湖县水产,外贸和湖泊管理等单位从上海的崇明岛购进天然蟹苗840公 Honghu Lake in the southern part of the Jianghan Plain, near the Yangtze River, the existing surface of 335 square kilometers, is the largest lake in Hubei Province. In 1982, an investigation team was formed by scientists and technicians from the provinces, prefectures and Honghu and Jianli counties to conduct a survey on the biological and non-biological environmental resources of Honghu’s fish, zoobenthos, microbes, aquatic plants, hydrology and meteorology Year comprehensive survey. After the investigation, carried out crab farming, seine fish farming, planting Ling and other plot test, take a very good economic benefits. However, the current output of Honghu Fisheries is not high, with an annual income of only 5 million yuan. In order to further improve the production efficiency of Honghu Lake, the following four ways of exploitation and utilization are proposed. 1. Development of crab farming According to the survey, the annual output of 49,000 tons of benthic animals, shrimp 2000 tons of shrimp and 157 tons of aquatic plants humus, which are good feed crab fattening. Production practice has proved that aquaculture crab quick, high income. In 1981 Honghu County Fisheries, Foreign Trade and Lake Management and other units purchased from Shanghai Chongming Island natural crab 840
