Method for intensive cultivation of ictalurus punctatus

Abstract

The invention relates to a method for intensive cultivation of ictalurus punctatus. The method comprises a step (1) of performing fingerling cultivation, a step (2) of performing adult fish cultivation, a step (a) of having pond conditions; a step (b) of performing preparation prior to stocking; a step (c) of performing stocking of fingerlings; a step (d) of feeding baits: adopting mixed domestication feeding of compound pellet feed and Chinese herbal medicine baits; a step (e) of performing daily management, and timely increasing the feeding amount of the Chinese herbal medicine baits by 15-20% of an original usage amount when fish disease is found. The Chinese herbal medicine baits are prepared from, by weight parts, 3-5 parts of nucleic acid yeast extract, 0.5-1 part of multi-vitamins, 10-15 parts of Chinese herbal medicine extract, 40-60 parts of enteric soluble polymers and 5-8 parts of vitamin E acetic ester. The Chinese herbal medicine baits used in the cultivation method are reasonable in compatibility, balanced in nutrition and low in processing cost, can remarkably improve immunity of ictalurus punctatus and greatly reduce the probability of edwardsienosis infection of ictalurus punctatus, is free of drug residue, leads to no drug resistance and is high in safety.

Description

technical field [0001] The invention relates to an intensive cultivation method for channel catfish. Background technique [0002] Channel catfish (Ictalurus punctatus), native to America, is also known as channel catfish. It has the characteristics of fast growth, wide temperature range and strong disease resistance. . Channel catfish meat is tender, delicious, rich in protein and unsaturated fatty acids, and is deeply loved by consumers in the United States, the European Union and other countries. However, due to its low local production, most of the demand depends on imports. The outlook is promising. [0003] In the intensive breeding mode of channel catfish, high stocking density is the basis for obtaining high breeding returns. Feeding high-grade feed can promote the growth of channel catfish, shorten the breeding cycle, and achieve early market launch. However, channel catfish is prone to intestinal sepsis during the breeding process. The symptoms are local redness...

At present, the farms mainly feed chloramphenicol or tetracycline baits for 5 consecutive days. In addition, 1.5-2.0 mg / L (water) of furan is splashed outside the body to improve the therapeutic effect. The above-mentioned drugs are very easy to pollute the water body. It is harmful to the environment, and antibiotics remain in the fish, which will easily cause drug resistance in the eaters and endanger human health. The present invention aims to provide a healthy and safe channel catfish intensive cultivation method
