Traditional Chinese medicine additive taming food conversion method for adult channel catfish

Abstract

Provided is a traditional Chinese medicine additive taming food conversion method for adult channel catfish. According to the traditional Chinese medicine additive taming food conversion method for the adult channel catfish, a pond meeting the requirements that water is clear, the depth ranges from 2.0m to 2.5m, and the pH value ranges from 7.0 to 8.5 is selected, and taming food conversion feed is put into the pond, wherein the taming food conversion feed comprises, by weight, 10-12 parts of fresh or frozen wild trash fishes, 8-10 parts of animal livers, 2-3 parts of humulus lupulus, 3-5 parts of tea saponin, 2-3 parts of fructus cnidii, 3-4 parts of ulmus macrocarpa hance and 1-2 parts of golden larch bark. The weight of the taming food conversion feed which is put into the pond and is fed to the adult channel catfish is 1-4% that of the adult channel catfish. The survival rate of the fry is increased by about 11%, the amount of pest and disease damage is reduced by 9%, the feed conversion ratio is reduced by 9%, and the per mu yield is increased by 16%. Therefore, traditional feed growth promotion agents can be completely replaced by the additive formula, the using effect is remarkable, the side effect does not exist, and higher economic benefit is created for farmers.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for taming adult channel catfish with traditional Chinese medicine additives. Background technique [0002] Channel catfish, also known as channel catfish and river catfish, is native to the Mississippi River in the United States and is the main freshwater farmed fish in the United States. Channel catfish are relatively large in size. Under artificial breeding conditions, the fish fry can grow into fish species with a body length of 14-20 cm and a weight of 0. 03-0. 10 kg in the first year. Reach 0. 8~ 1. 5kg. The front part of the fish is wider than the back part, the head is smaller, the snout is slightly pointed, the mouth is subterminal, and the upper and lower jaws have small and dense fine teeth. The body surface is smooth without scales, the mucus is abundant, the lateral line is complete, and there are obvious lateral line holes in the skin. There are 4 pairs of dark g...

Problems solved by technology

With the rapid expansion of the scale of channel catfish industrialization, the output per unit area of ​​intensive cages gradually increased, the environment of the breeding waters gradually deteriorated, and the farming techniques were not standardized, which led to an increasing number of channel catfish diseases and deaths caused by bacterial outbreaks Occurs from time to time, causing great economic losses to industrialized farming
