Large yellow croaker feed with effects of improving body color

Abstract

The present invention discloses a large yellow croaker feed with effects of improving body color. The feed comprises the following components in parts by weight: 25-30 parts of white fish meal, 5-10 parts of whey powder, 2-5 parts of earthworm powder, 2-5 parts of yeast powder, 5-10 parts of potato dregs, 10-15 parts of barley flour, 2-5 parts of wheat bran, 2-5 parts of sophora leaf powder, 2-5 parts of dried mulberry powder, 2-5 parts of ulva lactuca powder, 10-15 parts of refined fish oil, 2-5 parts of schizochytrium limacinum DHA algae oil, 5-10 parts of linseed oil, 2-5 parts of sea-buckthorn seed oil, 5-10 parts of body color-improving components, sodium selenite and other minerals, VB1 and other vitamins, Bacillus bifidus and other beneficial bacteria, and lysine and other essential amino acids. The feed is reasonable in formula and balanced in collocation, provides balanced nutrition for the large yellow croaker, and can play a significant role in improving the body color at the same time through the addition of the body color-improving components.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, and in particular relates to a large yellow croaker feed for improving body color. Background technique [0002] Large yellow croaker is one of the four traditional seafood in my country. In the early years, the annual output of large yellow croaker was very considerable in the Zhoushan fishing ground and the sea area of ​​Fujian. Wild large yellow croaker is not only golden in appearance, but also tender in meat and high in nutritional value, and is deeply loved by consumers. However, with the increase of offshore fishing intensity, the application of new fishing gear and fishing methods, especially the method of knocking knuckles, has greatly improved the productivity of large yellow croaker fishing. But the working principle of this method is to make the otoliths in the head of the large yellow croaker resonate and cause death through resonance, which inevitably leads to the death of th...

Problems solved by technology

[0004] However, through several years of breeding practice, it has been found that there are obvious differences in body color between farmed large yellow croakers and wild large yellow croakers. This difference seriously affects the appearance of farmed large yellow croakers, making it difficult to sell farmed large yellow croakers in the market. A good price will eventually dampen the enthusiasm of breeding enterprises, which is not conducive to the subsequent development of the industry
