Embodiment Construction

[0021] The technical scheme of the present invention is described in detail below in conjunction with specific implementation manners:

[0022] A method for cultivating sturgeon, comprising the steps of:

[0023] a. Disinfection of the flowing water pool. Disinfect the fish pond one week before stocking the seedlings. It can be disinfected with chlorine dioxide at a concentration of 2 ppm. Change the water after 2 days. Before stocking the fish species, turn off the water.

[0024] b. Put in fish species, buy large-scale cold-water fish species and put them into the flowing pool. After one month of breeding, they are divided into corresponding flow pools according to specifications.

[0025] c. The amount of water exchange, according to the water temperature, stocking density, etc., the exchange amount of water is controlled at 1-3 times per hour.

[0026] d. Feed and feeding, large-scale fish species can be directly fed compound pellet feed. In the fingerling stage, the nu...

Abstract

The invention discloses a sturgeon culturing method and belongs to the field of fish culturing. The sturgeon culturing method includes the steps of flowing water pond disinfection, fingerling releasing, water changing control, feed feeding, pest prevention and control and the like. By disinfection of a flowing water pond before culturing and pest prevention and control during feed raising, survival rate of sturgeon fingerlings is greatly increased; by preparing feed with different nutritional ingredients for fingerlings and adult fishes, digestion and absorption at different stages of sturgeon are facilitated, and growing is prompted.

Description

technical field [0001] The invention relates to a breeding method, in particular to a sturgeon breeding method. Background technique [0002] Sturgeon is a large, long-lived and ancient fish among the existing freshwater fishes in the world. It has a history of more than 200 million years and originated in the Cretaceous period hundreds of millions of years ago. "And "living fossils in water", it is an existing ancient biological population. There are many species of sturgeons in my country. The wild sturgeons in China include: Sturgeon spp., Sturgeon dabryi, and a small amount of Sturgeon Sakhalin distributed in the middle reaches of Heilongjiang River, the lower reaches of Songhua River, and the basin of Wusuli River; distributed in the Yangtze River and Jinsha River Chinese sturgeon, Dabry's sturgeon and white sturgeon in the watershed; naked belly sturgeon distributed in the waters of Yining, Suiding, Mibuqar and other places in Xinjiang; distributed in Siberia of Irtysh...
