Embodiment 1

[0024] The domestication and breeding of hybrid sturgeon seedlings was carried out in the Conghua seedling breeding base in 2012, and the breeding water was the bottom water of Maodun Reservoir. The culture container in the opening cultivation stage is a circular fiberglass tank with a diameter of 2m and a height of 40cm. The cultivation pond in the domestication cultivation stage is a circular octagonal flow pond with an area of ​​about 80 m 2 , the water depth is about 1m, with drainage in the middle.

[0025] The hybrid sturgeon larvae used in this example are the hybrid offspring of Sturgeon's sturgeon (♀) and Dabry's sturgeon (♂), which were purchased from the fishery of Guangzhou Xianbu Agricultural Technology Co., Ltd. About 1cm long.

[0026] The specific domestication and breeding steps are as follows:

[0027] (1) Open mouth cultivation

[0028] The number of hybrid sturgeon larvae is 4000 / m 3 The density is stocked in the culture container, the temperature of t...

Abstract

The invention discloses a hybrid sturgeon fingerling domestication and cultivation method. Mainly aiming at high sturgeon death rate in the high temperature period in summer and the phenomenon that sturgeons are hard to survive in summer in recent years, the invention provides a domestication and cultivation method which is more suitable for hybrid sturgeon fingerlings cultivated in the south. The method comprises the following steps: cultivating the hybrid sturgeon fingerlings to open mouth with live-bait for 7 to 8 days; feeding artificial compound feed to domesticate and cultivate the hybrid sturgeon fingerlings, and in the domestication and cultivation process, gradually adjusting the pH value of aquaculture water to be close to the pH value of water in the south; when the fingerlings grow to 8 to 10 cm, stopping domesticating and cultivating the hybrid sturgeons. The domesticated hybrid sturgeon fingerlings cultivated according to the method grow quickly and have a high survival rate and high economic benefits. The method provided by the invention has the advantages of simplicity and convenience in operation, low cost, easiness in popularization and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for domesticating and cultivating hybrid sturgeon seedlings. Background technique [0002] Sturgeon is a fish with high economic value. Sturgeon has the characteristics of large individual, late sexual maturity, fast growth, strong adaptability, and less disease, so it is suitable for artificial breeding. Hybrid sturgeon is the product of cross-breeding between species or genus of sturgeon. Hybridization of sturgeon parents with different biological characteristics can obtain gene recombination, so that new species that meet human needs can be selected from the hybrid offspring. Among them, the use of Dabry's sturgeon ( Huso dauricus ) (♀) and Sturgeon's sturgeon (♂), the resulting hybrid sturgeon has the advantages of fast growth, wide adaptability, and strong disease resistance. [0003] However, the contradiction that the demand for new high-quality ...
