Feeding method for high-yield selenium-enriched fish

Abstract

The invention relates to the technical field of aquaculture, and concretely relates to a feeding method for a high-yield selenium-enriched fish. The feeding method comprises the following steps: 1) constructing a pond, performing desilting, drying the pond in the sunlight, and performing fumigation disinfection treatment by using sulfur and formalin; 2) soaking fry in a salt-rice vinegar solutionbefore the fry are put; 3) throwing selenium-enriched feed for feeding, wherein the selenium-enriched feed is mainly prepared by performing fermentation on a plurality of raw materials such as selenium-rich corn flour, malt, selenium-enriched fish meal, cardamine hupingshanensis, astragalus bisulcatus roots, stanleya pinnata, red radix polygonum multiflori, spine date seeds, anemone hupehensis rhizomes, beetroots, Chinese chives, carrots, Chinese waxgourd peel, watermelon peel, cucumbers, bamboo shoots, shiitake and lignin peroxidase; 4) adding a water additive into water, wherein the additiveis mainly prepared from a plurality of raw materials such as tea seed cakes, argy wormwood leaves, sophora alopecuroides seeds, ampelopsis grossedentata, bacillus subtilis, photosynthetic bacteria and ferrous sulfate; and 5) performing fishing. According to the invention, the fishes fed by the feeding method are rich in selenium element and has low fat, the fish is fat but not greasy, the body weight is increased, the prevalence rate is reduced, and the use rate of chemical drugs is reduced.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a high-yield feeding method for selenium-enriched fish. Background technique [0002] Selenium has the functions of anti-oxidation, anti-aging, protecting and repairing cells, improving the oxygen-carrying capacity of red blood cells and human immunity, detoxifying heavy metals, and preventing cancer. Because of its delicious meat and rich polyunsaturated fatty acids, fish products have become a kind of meat product that is very beneficial to human health. Its consumption is increasing day by day and exceeds the growth rate of pork, beef and mutton, and it has become the main source of meat food. In recent years, with the unremitting efforts of agricultural science and technology workers and farmers, various kinds of selenium-enriched feed or feed additives have been produced, and selenium-enriched fish are cultivated, so that people can directly obtain seleni...

Problems solved by technology

However, the commercially available selenium-enriched feed has a single function and monotonous nutrition, and only a small part of the nutrients are absorbed and utilized by the fish, which is a waste of resources and high cost. If the fish cannot get the selenium, the nutrition will grow slowly and the weight gain will be slow, thereby reducing the selenium-enriched feed. fish economic benefits
