Fish feed rich in nutrition and preparation method thereof

Abstract

The present invention discloses a fish feed rich in nutrition and a preparation method thereof. The fish feed rich in nutrition is characterized by consisting of the following raw materials in parts by weight: 40-60 parts of corn flour, 20-30 parts of bran, 20-30 parts of soybean meal, 5-10 parts of fly maggot powder, 0.5-0.8 part of compound vitamin, 10-15 parts of attractants, and 5-8 parts of microbial compound bacteria. The attractants are products of one or more of betaine, garlic powder and cooking oil. The microbial compound bacteria include photosynthetic bacteria, bacillus subtilis, bacillus licheniformis, rhodopseudomonas palustris and denitrifying bacteria. By adding the microbial compound bacteria of the photosynthetic bacteria, bacillus subtilis, bacillus licheniformis and rhodopseudomonas palustris into the fish feed, the fish feed can increase the absorption of the fish to nutrients, at the same time can play a good role in purifying water quality, and thus increase the immunity and survival quantity of the fish.

Description

【Technical field】 [0001] The technical field of the fish feed of the present invention, especially the technical field of a nutrient-rich fish feed and its preparation method. 【Background technique】 [0002] With the emergence of intensive aquaculture, the aquaculture density has increased significantly, leading to an increase in residual ears and animal excrement in the water. Under such environmental conditions, it promotes the excessive reproduction of harmful algae, and the content of COD and ammonia nitrogen in the water rises. Oxygen level decreases, thereby gradually reducing the stock of fish. The existing fish feed generally does not contain microorganisms that can purify water quality and help fish absorb nutrients. Therefore, the existing fish feed can only provide nutrition. The role of the fish, but can not increase the immune ability of fish and increase the role of fish survival. 【Content of invention】 [0003] The purpose of the present invention is to sol...

[0002] With the emergence of intensive aquaculture, the aquaculture density has increased significantly, leading to an increase in residual ears and animal excrement in the water. Under such environmental conditions, it promotes the excessive reproduction of harmful algae, and the content of COD and ammonia nitrogen in the water rises. Oxygen level decreases, thereby gradually reducing the stock of fish. The existing fish feed generally does not contain microorganisms that can purify water quality and help fish absorb nutrients. Therefore, the existing fish feed can only provide nutrition. effect, but cannot increase the immune ability of fish and the effect of increasing fish survival
