Feed for preventing silurus lanzhouensis gill rot and preparation method thereof

Abstract

The invention relates to a fish feed, in particular to a feed for preventing silurus lanzhouensis gill rot and further relates to a preparation method of the feed for preventing silurus lanzhouensis gill rot. The feed for preventing silurus lanzhouensis gill rot is prepared from, by mass, 20-30 parts of fish meal, 8-15 parts of earthworm meal, 4-10 parts of squid meal, 6-12 parts of rice bran, 3-7 parts of fresh ginger, 3-8 parts of golden cypress, 2-6 parts of purslane, 3-7 parts of jasmine, 2-5 parts of asparagus, 2-6 parts of pyramidomonas delicatula, 1-5 parts of Platymonas subcordiformis, 1-4 parts of cuttle bone, 2-6 parts of purple perilla, 1-4 parts of dandelion, 1-4 parts of olive oil and 1-4 parts of composite multivitamins. The feed for preventing silurus lanzhouensis gill rot is provided according to the silurus lanzhouensis energy metabolism mode and nutrient requirement; after silurus lanzhouensis is fed with the feed, the feed coefficient is low, the specific growth rate is high, and the gill rot resistance is high.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for preventing gill rot disease of Lanzhou catfish; the invention also relates to a preparation method of the feed for preventing gill rot disease of Lanzhou catfish. Background technique [0002] Lanzhou catfish has a long body, relatively flat head, smooth body surface without scales, skin rich in mucus, and a line of mucus holes on the lateral line. The eyes are small, the mouth is wide and large, the lower jaw is protruding, and there are 2 pairs of barbels, which are longer than the base of the pectoral fin. Body posteriorly flattened. The end of the cleft is opposite to the edge of the eye. The dorsal fin is small, and the posterior edge of the pectoral fin spines is extremely weakly serrated. Lanzhou catfish is similar to small dorsal catfish, catfish, bigmouth catfish, Kunming catfish, and Fuxian catfish, but there are also significant differences. [0003] At present, during the...

Problems solved by technology

[0003] At present, during the cultivation of Lanzhou catfish, due to continuous fertilization and bait feeding, the remaining dung and residual bait are most likely to damage the water quality, which often causes Lanzhou catfish to have gill rot disease. When people deal with fish diseases, they often use them according to the condition. The method of splashing bactericidal disinfectant, but the drug will more or less produce side effects or toxicity. Although it can kill the pathogenic bacteria on the body surface and water of Lanzhou catfish, it often causes water pollution, and long-term use will cause the drug to accumulate and affect Body health, which in turn affects the growth rate of Lanzhou catfish

During the growth process of Lanzhou catfish, insufficient nutrition often leads to insufficient resistance and gill rot disease on the body surface, which affects the survival rate of Lanzhou catfish. The Lanzhou catfish compound feed for the growth and development of Lanzhou catfish is an urgent problem to be solved in the current Lanzhou catfish breeding industry
