Problems solved by technology

However, the natural bait in the paddy field fish farming model is insufficient to meet the needs of fish growth. Feeding feed can easily cause nutrient loss and non-point source pollution, which is not conducive to the growth of rice. Moreover, the prevention and control of fish diseases in the paddy field fish farming process is also a difficult point.
Patent CN112189520A discloses a method for ecological breeding of rice and fish. This method solves the problem of additional nutrition for fish by feeding fish feed at regular, fixed, quantitative, and qualitative levels. However, the feed fed by this method is full-price puffed Feed, easily lead to overnutrition of fish and water
[0003] There is currently no feed designed for fish farming in the paddy-fish farming model, so it is necessary to develop a feed suitable for fish farming in the paddy-fish farming model

Abstract

The invention provides rice-fish integrated fish feed and a preparation method thereof. Rice hull powder, eel powder, nostoc flagelliforme, monocalcium phosphate, aloe powder, euryodendron excelsum, carvacrol, garcinia multiflora oil, herbs of elegant tickclover, multivitamins, glutathione and mica powder are selected as feed raw materials through scientific proportioning according to the ingestion characteristics of fish and food sources in a rice field. Nutritional ingredients required by growth and development of fishes are supplemented, the immunity of the fishes is enhanced, and the morbidity is reduced. The euryodendron excelsum, the garcinia multiflora oil and the herbs of elegant tickclover are matched for use, so that the immunity of the fishes can be enhanced, the euryodendron excelsum, the garcinia multiflora oil and the herbs of elegant tickclover are matched for use with the rice hull powder, the eel powder, the nostoc flagelliforme, the monocalcium phosphate, the multivitamins and the glutathione, the nutritional requirements of the fishes can be met, the fish meat quality is improved, and by adding the mica powder and the aloe powder prepared by the method, the stability of the pellet feed in water is improved, and fish diseases caused by water pollution caused by the pellet feed are prevented. Compared with the traditional expanded feed, the fish feed disclosed by the method can fully retain vitamin components in the raw materials.

Description

technical field [0001] The invention relates to the technical field of ecological planting and breeding, in particular to a fish feed for rice-fishing co-culture and a preparation method thereof. Background technique [0002] Rice-fishing cooperative farming is a three-dimensional breeding model that organically combines rice planting and fish farming. It uses the movement of fish to loosen the soil, increase the oxygen content in the water, and eat most of the eggs and larvae in the soil, reducing the Insect pests, and fish excrement rich in nitrogen, phosphorus, potassium and other nutrients have become high-quality rice field fertilizers. The rice-fish farming model can obtain stable aquatic products, reduce the input of chemical fertilizers and pesticides, control non-point source pollution, and at the same time ensure the quality of rice. However, the natural bait in the paddy field fish farming model is insufficient to meet the needs of fish growth. Feeding feed can e...
