Fishery-lightening integrated ecological grass carp culture feed as well as preparation method and application thereof

Abstract

The invention belongs to the field of aquaculture and especially relate to a fishery-lightening integrated ecological grass carp culture feed as well as a preparation method and an application thereof. The fishery-lightening integrated ecological grass carp culture feed is characterized by comprising the following ingredients in parts by weight: 1.5-2.5 parts of Chinese herbal medicines, 18-22 parts of fish meal, 10-14 parts of bean meal, 4-6 parts of corn protein powder, 1-3 parts of rice protein powder, 9-11 parts of rapeseed meal, 9-11 parts of cottonseed meal, 15-17 parts of bran, 15-17 parts of flour, 1-3 parts of calcium dihydrogen phosphate, 3-5 parts of fish oil and 0.5-1.5 parts of premixed feed for the grass carps. According to the invention, photovoltaic modules are set up on the water surface to generate electricity while the fishes are cultured under the water surface, so that a mode in which 'electricity can be generated above the water surface while fishes can be cultured under the water surface' is formed. Thus, land resources are saved, environment is improved and unit incomes of the fish ponds are increased.

Description

technical field [0001] The invention belongs to the field of aquaculture and new energy, and in particular relates to an ecological grass carp breeding feed with fish and light integration, a preparation method and application thereof. Background technique [0002] my country's total land area ranks third in the world, but the per capita land area is only 0.777 hectares, only 1 / 3 of the average level. "More people and less land" is the basic national condition of our country. Therefore, cherishing and rationally using every inch of land is the basic national policy of our country. The national aquaculture area is 8,088.40 thousand hectares, which is a large aquaculture area. However, traditional aquaculture only has a single income from aquatic products, which is a great waste of resources for our country where land resources are scarce. How to make full use of land resources for aquaculture is worthy of attention and consideration. Our country not only lacks land resource...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides an ecological grass carp breeding feed with fish and light integrated, which is mainly made of special Chinese herbal medicine, which is non-toxic and harmless, and produces ecological grass carp; the fish and light integrated are used in the breeding method to make full use of the land Resources, on the one hand, it solves the problem of shortage of land for the photovoltaic industry, on the other hand, it solves the technical problem of low efficiency in pond aquaculture, low production cost, and simple and easy-to-operate farming methods
