Special feed for intercropping yellow-head catfish and erythroculter ilishaeformis

Abstract

The invention relates to special feed for intercropping yellow-head catfish and erythroculter ilishaeformis. The special feed comprises following components by weight: fish meal, corn flour, soybean pulp, peanut powder, soybean meal, cottonseed, lecithin, flour, brown sugar, compound vitamin, a compound mineral substance, methionine, ferric sulfate, copper sulfate, zinc sulfate and manganese sulfate. According to the special feed, the components are mixed uniformly according to the ratio, the fish meal, the corn flour, the flour, and the like are used as the main raw materials, the brown sugar, the compound vitamin, the compound mineral substance and the sulfates are added, and the components are mixed with water according to a certain ratio, smashed and granulated into particles having a common particle size to feed fish. After being fed, the two kinds of fish grow fast, the conversion rate of the feed is high, the food coefficient is 1.4-1.5, the disease resistance and anti-stress capability of the two kinds of fish are significantly enhanced, and the final output is high.

Description

technical field [0001] The present invention relates to the technique of nested culture of red catfish and yellow catfish field In particular, it is a special feed for cross-breeding red catfish and yellow catfish. Background technique [0002] The red squid is large in size, slender, and flat on the side. It is also known as Qiaozuiba, white striped fish, etc. Its meat is white and tender, with high nutritional value, strong adaptability and disease resistance. Less, able to tolerate hypoxia. Yellow catfish has a long body, a flat ventral surface, and a flattened rear half of the body. It is also known as yellow-finned fish and yellow-bitten bone. Its meat is delicious, fatty, and has no small spines. It is a common edible fish in my country. According to people's research, red catfish and yellow catfish can be nested, that is, the two are cultured in the same water body according to a certain ratio, which will greatly increase the output of the two and improve the bait c...

Problems solved by technology

[0003] During the above-mentioned sampling process, the water quality of the water body needs to be carefully cultivated and adjusted. There is also a certain ratio requirement for the amount of the two seedlings. In addition to these, it is also necessary to pay attention to the bait formula that is usually fed. Many farmers choose the formula in order to reduce costs. The components and proportions of the fish are relatively random, which is not conducive to the improvement of the survival rate and yield of the red catfish and yellow catfish, and finally reduces the bait coefficient and increases the breeding cost
