Method for ecologically cultivating grass carps in sloping fields in southern hilly regions

Abstract

The invention provides a method for ecologically cultivating grass carps in sloping fields in southern hilly regions, and belongs to the field of aquaculture. The method comprises the following steps: S1, site selecting: a sloping field with a continuous stream is selected in the southern hilly region; S2, pond building: building a plurality of cement ponds with the length of 8 meters, the width of 2 meters and the depth of 1.6 meters, wherein the plurality of the cement ponds are distributed in a step shape; S3, disinfection: sterilizing and disinfecting the cement ponds by using a disinfectant every year before fish fries are put into the ponds, and putting quick lime into the cement ponds for disinfection every month; and S4, cultivation: feeding a synthetic feed into the cement ponds every day, wherein the weight of the synthetic feed is 1.8-2.5% of the weight of the fish, and putting tender bamboo leaves or pennisetum hydridum into the cement ponds, wherein the weight of the bamboo leaves or pennisetum hydridum is 0.5-1.2% of the weight of the fish. A large number of grass carps can be cultivated in the sloping field; meanwhile, the feed fed every day is formulated by a large amount of practices, so that the meat of the fish is smooth and tender and refreshing, and the grass carp can be prevented from suffering from enteritis.

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
