Method for ecologically breeding grass carp in slope of southern hilly country

Abstract

The invention provides a method for ecologically breeding grass carp in a slope of a southern hilly country, and relates to the field of aquaculture. The method comprises the following steps: S1, performing site selection: selecting the slope, with a continuous-stream brook, of the southern hilly country; S2, building ponds: building a plurality of cement ponds which are distributed in a ladder-like mode; S3, disinfecting: sterilizing and disinfecting the cement ponds by using disinfectors before putting fish fries every year; S4: breeding: putting 1.8 to 2.5 percent of synthetic feed, 0.3 to 1.0 percent of young bamboo leaves or pennisetum hydridum and 0.1 percent of duckweed every day based on the weight of the fish. By the method, the plurality of cement ponds in ladder-like arrangement are arranged in the slope, the two adjacent cement ponds serve as a group, each group of cement ponds comprise a grass carp pond and a treatment pond, the grass carp pond is used for breeding the grass carp and the treatment pond is used for treating waste generated by grass carp feeding, so that a large amount of grass carp can be bred in the slope; meanwhile, the feed which is put every day is prepared by a large number of practices, so that the meat quality of the grass carp 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. Lively, swims quickly, and often feeds 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 same time, gra...

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
