Method for ecologically breeding grass carps in southern hilly land slope

Abstract

The invention provides a method for ecologically breeding grass carps in a southern hilly land slops, and relates to the field of aquaculture. The method comprises the following steps of S1, address selection: selecting a slope with a constantly flowing stream in southern hilly land; S2, pool building: building a plurality of cement pools distributed in a step shape; S3, disinfection: performing sterilization and disinfection on the cement pools by using disinfectants before the fish fry feeding every year; S4, breeding: feeding compound feed every day according to 1.8 to 2.5 percent of the fish weight; feeding tender bamboo leaves or pennisetum hydridum according to 0.3 to 1.0 percent of the fish weight; feeding duckweeds according to 0.1 percent of the fish weight. The method provided by the invention has the advantages that the plurality of cement pools distributed in the step shape are arranged in the slopes; every two adjacent cement pools form one group; each group of cement pools comprises a grass carp pool and a processing pool; each grass carp pool is used for culturing the grass carps; each processing pool is used for processing waste materials generated by the grass crap breeding; a great number of grass carps can be bred on the slope; meanwhile, the feed fed every day is prepared through a great number of practices, so that the meat of the grass carps is smooth, tender and refreshing.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for ecologically cultivating grass carp on slopes in southern hilly areas. Background technique [0002] Grass carp is a freshwater creature that inhabits rivers and lakes in plain areas, and generally prefers to live in the middle and lower layers of water and areas with many aquatic plants near the shore. It is lively, swims quickly, and often looks for food in groups. Because of its rapid growth and wide source of feed, it is one of the four major domestic fish in freshwater farming in China [0003] The southern hilly areas are rich in water sources, but have less flat land. With the growth of China's population and the development of society, more and more flat land is used to build houses and factories. As the scope of land acquisition becomes wider and wider, agricultural land is gradually reduced. , the production range of grass carp is also gradually reduced; at the...

Problems solved by technology

[0003] The hilly areas in the south are rich in water sources, but there are few flat lands. With the growth of China's population and the development of society, more and more flat lands are used to build houses and factories. As the scope of land acquisition becomes wider and wider, agricultural land is gradually reduced. , the production range of grass carp is also gradually reduced; at the same time, grass carp likes to live in relatively clean waters, and ordinary fish pond culture needs to clean the impurities in the fish pond frequently, which also increases the burden on farmers; therefore, providing a It is imminent to replace some of the original grass carp cultured in plain lakes with new farming methods to produce high-quality grass carp
