Quick breeding method for paddlefishes

Abstract

The invention relates to a quick breeding method for paddlefishes. The quick breeding method comprises steps of parent fish selection, artificial semen collection, artificial hatching and hatching management. In the artificial hatching step, fertilized eggs are stood for a while and then cleaned by water; the fertilized eggs are poured into a talcum powder turbid liquid and stirred more than 50 minutes; the fertilized eggs lose viscosity due to adhesion to the talcum powder; when all egg granules become disperse particles and do not agglomerated when stood; and the fertilized eggs are cleanedand placed into an incubator for hatching. In the hatching management step, fresh water is injected when fish eggs are placed into the incubator; and a piece of filter sieve cloth has to be frequentlywashed during the hatching and a proper amount of fungicide is added before hatching is completed. By the use of the quick breeding method for the paddlefishes, beneficial effects of high breeding rate, quick breeding speed, high survival rate and output and strong disease resistance can be achieved.

Description

technical field [0001] The invention relates to a rapid breeding method of the spoonbill sturgeon, which belongs to the technical field of aquaculture. Background technique [0002] Spoon-nose sturgeon, also known as duck-billed sturgeon, is a large freshwater and precious economic fish native to the United States. It can survive normally at a water temperature of 0-37°C. Its feeding habits are similar to those of bighead carp. Its cost is low, its growth is very fast, and it is easy to catch. Eggs, meat, and skins have extremely high economic value. One of the fine breeds for income. [0003] Although my country achieved success in artificial breeding of the sturgeon in 2001, the development of the breeding industry of the sturgeon has been restricted due to the small number of parents, imperfect breeding technology, small breeding scale and shortage of large-sized seedlings. [0004] Therefore be necessary to design a kind of rapid breeding method of spoon-nose sturgeon,...
