Embodiment 1

[0010] The pure-bred A. chinensis has a smooth body surface and no scales. The natural breeding period is concentrated in the middle and late October. It is a high-quality local fish species with relatively abundant reserves in the Heilongtan Reservoir in Shilin County. It has high scientific research value and market development potential. In the process of domestication, in addition to meeting the living conditions of golden thread fish as far as possible according to their living habits, the gonadotropin IHRH-A was added to the feed from September 10. 2 and nine-vitamin complex vitamins, add 1 million international units of 2 IHRH-A per 500 grams of feed 2 , 5 to 10 grams of nine-vitamin complex vitamins to promote normal reproductive growth and natural spawning and reproduction. After October of that year, the golden thread fish began to reproduce naturally in the pond imitating the natural spawning environment, and in the middle and late December, groups of small fry wit...

Embodiment 2

[0012] The reserves of big-headed golden thread fish in Heilongtan Reservoir are relatively small, and compared with pointed-headed golden thread fish, its reserves are only about 10-20% of that of pointed-headed golden thread fish. Under natural environmental conditions, the gonads of the third-year-old gold thread fish with a weight of 200 grams are mature, they lay eggs and reproduce in February to March, and at the end of the month, 200 to 300 grams of gold thread fish with a weight of 200 grams can be collected by gillnet 25 The tail, which initially has the conditions for natural spawning or artificial breeding, is put into the artificial pond at the foot of the reservoir dam for domestication, and the gonadotropin IHRH-A is added to the feed in August of the first year. 2 and nine-vitamin complex vitamins, add 1 million international units of 2 IHRH-A per 500 grams of feed 2 , 5-10 grams of nine-vitamin complex vitamins. In May of the next year, scattered larvae with a ...

Abstract

A method for the reproduction of golden threadfin bream includes such steps as culturing the wild golden threadfin bream in artificial pond, controlling proper temp and environment, and adding the gonad stimulating hormone IHRH and composite vitamin prepared from 9 vitamins to the bait in the August.

Description

technical field [0001] The invention relates to a golden thread fish breeding method, which belongs to a method for artificially breeding golden thread fish by simulating the natural environment in which the golden thread fish lives. Background technique [0002] Golden thread fish is the first of the four famous fishes in Yunnan (gold thread fish, bow fish, bullhead fish, and Kanglang fish). It is not only tender and delicious, but also has certain medicinal value. Gold thread fish is a well-known native fish species known to young and old in Kunming. The gold thread fish in Yangzonghai used to account for 70% of the fish production in the lake. Zhongyanze in Luliang County (now Luliang Overseas Chinese Farm) once produced gold thread Line fish is 30-40 tons, and there is also a certain amount of boluo fish (that is, golden thread fish) in Fuxian Lake. With the inadvertent introduction of the species, the invasion of a large number of egg-eating small miscellaneous fish, a...
