Method of applying music to oviposition and insemination of four major Chinese carps

Abstract

The invention relates to a method of applying music to oviposition and insemination of four major Chinese carps and belongs to the technical field of fish propagation. In the artificial propagation of the four major Chinese carps, under the condition that parent fishes generate resistance to exogenous hormone drugs year by year, the music is introduced to induce estrus and spawning. In the invention, the music which is suitable for the estrus induction of fishes is selected and edited to corresponding segments and is correspondingly played according to emotional changes of the fishes from estrus beginning to spawning, ejaculation and insemination end phases to ensure that the fishes can naturally mate, spawn and inseminate under the synergistic action of the music and the hormone. Therefore, the problems that in the traditional artificial propagation of the four major Chinese carps, the fishes generate drug resistance because only the hormone drugs are injected to induce estrus and spawning, the estrus of the fish body is insufficient, and the parent fishes are wounded and the death rate is high because of forcibly extruding sperm and ovum artificially can be solved; and the method has the advantages of increasing the spontaneous labor rate of the parent fishes, reducing the death rate of the parent fishes and increasing the propagation efficiency of the fishes.

Description

1. Technical field [0001] The invention belongs to the technical field of fish reproduction. 2. Background technology [0002] The four major carps (herring, grass carp, silver carp, and bighead carp) are the main freshwater fishes in my country, and the sources of their fry are all obtained through artificial breeding. The artificial reproduction of the four major domestic fishes is usually divided into the following four steps: 1. Select broodstock, 2. Inject hormone drugs to aphrodisiac and induce labor, 3. Artificially squeeze eggs for insemination, and 4. Collect eggs for hatching. The biggest deficiency of this method is to easily cause broodstock to be injured and die. The annual mortality rate of broodstock caused by artificial breeding is about 10%. The price of each broodstock is more than RMB 1,000. [0003] The use of music for human rehabilitation, cow lactation, tomato growth, etc., has been reported, and all have been successful. Fish in the water can perc...

Problems solved by technology

So as to solve the problem of the artificial breeding of the four major domestic fishes, only the injection of hormone drugs to aphrodisiac to induce drug resistance, the lack of estrus in the fish body, artificial hard squeezing of sperm and egg insemination, resulting in the high death rate of parental insemination
