Jiangsu Sihong built 200000 Mu tidal flat to develop aquaculture

Introduction: Sihong County, Jiangsu Province makes full use of the scientific and technological test results to develop aquaculture It has built 200000 Mu beach spark technology base in linhuai, Bancheng, Longji, Chengtou, Sihe and other towns around Hongze Lake, Tiangang lake and erzui lake Up to now, there are 68 aquatic research projects in Sihong County, which have filled the gap of national and provincial aquatic research In Sihong County, Hongze Lake, Tiangang lake, erzui lake, as well as the tidal flat water surface of ditch, river, pond and reservoir are 1.66 million mu Among them, the beach water surface of Hongze Lake has 1.16 million mu in the county In the past, the beach development in this county has been on the traditional and extensive level, with low and unstable economic benefits In recent years, the county has set up a leading group for the implementation of aquatic science and technology projects, a scientific and technological research group and an experimental demonstration group, as well as a private Aquatic Research Institute, etc The county wide aquaculture high-yield and efficient scientific and technological research activities Since 1996, the county's provincial special aquaculture science and technology demonstration park has undertaken 45 science and technology projects issued by the province, city and county, and more than 20 scientific research achievements have won awards and been popularized In 1997, Sihong County, the Provincial Academy of Agricultural Sciences and the National University of Singapore established the "artificial sea water crabs breeding farm" on the Bank of Hongze Lake, conquered the problem of crabs breeding, and made the survival rate of crabs more than 40%, more than double the normal level, and a large one The cost per mu can also be reduced to less than 700 yuan, making the crabs breeding in the whole county to a new level Sihong County also relies on special aquaculture science and technology park to drive the upgrading of aquaculture in the whole county In recent years, the science and technology park has successively introduced and cultivated more than 20 kinds of new special aquatic products that are popular in the market, such as Allogynogenetic crucian carp, California perch and South American white shrimp Last year, it successfully hatched Pelteobagrus fulvidraco fry, adding new members to the "water nobility" of Hongze Lake At the same time, the county also promoted the "rice crab co farming" in half cities and the "rice duck co farming" in Chengtou township The results are as follows: digging ditches to collect water and setting up plastic anti escape walls, planting rice in the middle, raising crabs and ducks in the ditches, putting natural baits such as snails and Elodea that crabs like to eat in the ditches, mixing garlic with crabs' feed, feeding them directly after crushing, preventing the occurrence of bacterial diseases, making the fish, shrimp and crabs live in the primitive ecology as if they had no effect on human body In addition, the composition of mercury is 17% lower than the national standard Crabs crawling in rice fields provide the best organic fertilizer for rice growth Crabs and ducks also eat insects in rice fields, without fertilizer and pesticide, there is no pollution In June 1998, the "golden water" hairy crab and "crab garden" rice produced by "rice crab co cultivation" and "rice duck co cultivation" in the county were recognized as organic food by the organic food development center of the State Environmental Protection Administration, and the products entered the international markets such as South Korea, Japan and Singapore This year, the villages and towns along the lake in the county have imitated the scientific cultivation method of Bancheng and Chengtou, and the ecological project of "rice and crab co cultivation" and "rice and duck co cultivation" has been completed At present, Shanghai, Guangzhou, South Korea, Japan and other Chinese and foreign businesses have come to Sihong to book and buy "crab garden" rice after hearing the news.
