specific Embodiment approach 1

[0007] Specific embodiment one: the method for the artificial induced spawning breeding of the red cymbal in this embodiment is realized according to the following steps: 1. From late April to early May each year, the body surface of the red cymbal is sterilized and then put into the pool water with fresh water quality , cultivated in a breeding pond with sufficient bait; 2. From late June to early July, under the condition of a temperature of 18-26°C, individuals with normal development, no fish body injury, smooth body surface and healthy physique are used as broodstock. Inject chorionic gonadotropin into the broodstock, and inject again after an interval of 8-12 hours. After 6-10 hours, the broodstock will ovulate by itself; 3. Put the eggs in the hatching bucket for 4-6 days; 4. Inflate the intestinal tube in the swim bladder After opening, put the seedlings into an outdoor pond to cultivate them into juvenile fish; in step 1, during the cultivation process, at intervals of...

Abstract

An artificial inducement method for spawning and breeding erythroculter ilishaeformis relates to an artificial inducement method for spawning and breeding fish. The method solves the problems of a low hatching rate and a low post-natal survival rate in the existing artificial reproduction method of the erythroculter ilishaeformis. The breeding method comprises the following steps: 1. culturing parent fish in a culture pond; 2. injecting an aphrodisiac agent into the parent fish twice so that the parent fish autogenously spawns; 3. transferring the fish eggs into a hatching barrel for hatching; and 4. transferring fish fry into an outdoor pond after opening an inflatable intestinal canal of a fish maw so as to culture young fishes. The artificial inducement method for spawning and breeding of the erythroculter ilishaeformis can help shorten a breeding period, greatly improve the survival rate and the hatching rate of the parent fish, and obviously improve the economic benefit.

Description

technical field [0001] The invention relates to a method for artificial induced breeding of fish. Background technique [0002] Commonly known as big white fish, cocked mouth, cocked shell, white silk, Xingkai big white fish, cocked carp, stinging fish, cocked white, white fish, pouting carp, etc., it is distributed all over the country. Xingkai The red bream is an independent subspecies of the red bream in the waters of Xingkai Lake. It is a treasure in the water of Xingkai Lake. It is one of the four famous freshwater fishes in China. It is large and long and can weigh dozens of kilograms. Fresh and tender, steamed with a taste of crabmeat, the fish soup is as white as milk, with high nutritional value, containing 18.6 grams of protein and 4.6 grams of fat per 100 grams of meat; however, due to the increasingly harsh natural environment, serious water pollution and overfishing As a result, the output of red bream in Xingkai Lake is declining year by year, and the market p...
