Problems solved by technology

[0003] The suitable water temperature for Yunnan light-lipped fish is 5-28°C, and the optimum water temperature is 14-24°C. It likes to live in a clear water environment. It mainly lives in the middle and upper layers of the water body. It has a strong ability to jump against the water. , the seedling stage mainly feeds on rotifers and fleas, and can feed on filamentous baths and rotten organic debris when it is above 4cm; Yunnan light-lipped fish has tender meat, high DHA and EPA content, and is very popular among consumers. Due to its habitat Human activities such as destruction and overfishing have caused a sharp decline in the wild resources of the Yunnan smooth-lipped fish, and the market price is high. Carrying out artificial breeding of the Yunnan smooth-lipped fish and realizing large-scale production of seedlings is an important way to protect the wild resources of the Yunnan smooth-lipped fish and meet the artificial needs of natural waters. There is an urgent need to increase breeding and ensure market supply; at present, the main problems in the reproduction of Yunnan smooth-lipped fish are: most of the breeding parents rely on wild fishing, the number cannot be guaranteed, and the spawning is not concentrated, making it difficult to achieve large-scale production of seedlings
[0004] In the current technology, there are many researches on the reproduction and growth of Yunnan light-lipped fish. For example, the patent number is CN201611167311.2, a kind of artificial reproduction method of light-lipped fish. Higher reproduction is achieved through domestication of young fish, selection of parents, and use of hormones effect, but the study did not consider the overall growth environment of the fish, but only focused on the selection of the fish body and the use of hormones, and could not maximize the reproductive performance of the Yunnan smooth-lipped fish; another example is the patent number CN201610109556.3 A high-efficiency artificial breeding method for bald-lipped fish, which mainly achieves the purpose of high reproduction through the use of breeding equipment, but the document does not dig deep into the ecological habits of bald-lipped fish in Yunnan, nor can it maximize the use of licked-lipped fish in Yunnan Therefore, the current technology lacks a comprehensive consideration of nutrition and growth environment, so as to maximize the reproductive effect of Yunnan smooth-lipped fish and promote the large-scale cultivation of Yunnan smooth-lipped fish

Abstract

The invention belongs to the technical field of breeding, in particular to a method for artificial breeding of Yunnan smooth-lipped fish. The three steps complement each other, using a suitable environment, providing sufficient protein bait and hormone stimulation, to promote the efficient breeding of Yunnan light-lipped fish.

Description

technical field [0001] The invention relates to the field of culture technology, in particular to a method for artificial breeding of Yunnan light-lipped fish. Background technique [0002] Yunnan smooth-lipped fish is mainly distributed in Jinsha River, Nanpan River and their affiliated lakes in Yunnan. After the 1960s, the resources decreased sharply, and it almost disappeared in the 1980s. Yunnan smooth-lipped fish is rich in nutrition, tender and delicious. In order to protect and develop the resources of Yunnan smooth-lipped fish, through the practice and research of relevant technical personnel, artificial breeding of Yunnan smooth-lipped fish was realized in 2014. and other places have carried out the artificial breeding of Yunnan light-lipped fish. [0003] The suitable water temperature for Yunnan light-lipped fish is 5-28°C, and the optimum water temperature is 14-24°C. It likes to live in a clear water environment. It mainly lives in the middle and upper layers o...
