Embodiment 1

[0030] Embodiment 1: Fuxian four-bearded barb artificial propagation technology, comprises the following steps:

[0031] (1) Fish pond construction

[0032] Choose to build fish ponds around Fuxian Lake in Yunnan to simulate the environment in Fuxian Lake, and do a good job of disinfection and sterilization of the fish ponds, and finally put the water in Fuxian Lake to maintain a certain degree of fluidity;

[0033] (2) Selection of broodstock

[0034] Every June, select broodstock with strong physique, no disease and injury, and well-developed gonads to artificially induce labor; the sexually mature Fuxian four-bearded barb changes from the original yellow-green color to yellow and deepens, and the female and male are easier to distinguish; the abdomen of the female fish is Enlarged, with occasional outlines of ovaries, reddish cloaca, fullness and softness to the touch of the abdomen; white pearls on the proboscis of the male fish are obvious, and there are obvious spikes w...

Abstract

The invention belongs to the technical field of breeding and discloses a barbodes fuxianensis artificial propagation technology. The barbodes fuxianensis artificial propagation technology includes the steps of fishpond building, parent fish selection, oxytocic injection, parent fish management before oviposition, artificial insemination, artificial incubation and fingerling breeding. By means of the barbodes fuxianensis artificial propagation technology, fingerling can be provided for the society, and artificial breeding through dam pools and reservoirs can be popularized; fishermen can obtain economic benefits, meanwhile, fishery innovation can be accelerated, life of people can be improved, and economic prosperity in rural areas can be promoted; a certain amount of fingerling can be led into the Fuxian Lake so as to protect the species diversity of the Fuxian Lake, optimize fish fauna composition, keep ecological balance, protect aquatic wildlife and increase the yield of brand-name and high-quality aboriginal fish; in addition, substances in a large water body are transformed into nutrient substances every year, so that water is purified, the environment is protected, and the water quality of the Fuxian Lake is protected.

Description

technical field [0001] The invention relates to an artificial propagation technology of Fuxian four-bearded barb, which belongs to the field of breeding technology. Background technique [0002] Fuxian four-bearded barb is a rare and valuable indigenous fish in Fuxian Lake, and it is now on the verge of extinction in Fuxian Lake. Fuxian Lake is the second deepest freshwater lake in China, with a maximum water depth of 158.9m and a water storage capacity of 20.62 billion m3, accounting for 72.8% of the total water storage of the nine plateau lakes in Yunnan Province and 9.16% of the national freshwater storage. %, rich in indigenous fish resources, known as the "live fish museum", is an important part of the development of plateau characteristic fishery, and provides a valuable material basis for the realization of artificial economic development. With the continuous improvement of people's living standards, high-quality aquatic product breeding and characteristic fishery ec...
