Embodiment Construction

[0006] The present invention is 8.35 with pH, ​​salinity is 1706.61mg / L, and alkalinity is 507.55mg / L, and hardness is 465.13mg / L, and water type is the water resource of magnesium sulfate type III to carry out industrialized seedling raising and intensification of sturgeon Aquaculture, aquaculture water is purified by circulating filtration and water quality is purified with beneficial microorganisms and photosynthetic bacteria. After filtration and biological purification, the aquaculture water is lifted to a high-level pool by a submersible pump for self-flow, so that the aquaculture pool can flow continuously every day and ensure 200% of the water exchange volume; The seedlings are sterilized with 0.5% salt water and placed in glass fiber reinforced plastic basins for cultivation. The seedling density is Φ2m and the volume is 1M 3 The density depending on the cultivating pot is: 500 fish / pot with a body length of 7-10cm, 700 fish / pot with a body length of 5-7cm; select larg...

Abstract

The present invention is Siberia sturgeon cultivation in plateau saline-alkali water and aims at solving the technological problems of raising sturgeon fry and cultivating adult sturgeon in plateau saline-alkali water. The industrial Siberia sturgeon cultivation method includes: lifting water for cultivation to high water reservoir to maintain constant water flow in the cultivation pond; sterilizing sturgeon fry and pot cultivation in certain density; feeding for six times each day in the daily feed amount of 8 % of fry weight; pond cultivation of large fry and adult sturgeon in certain density; sterilizing with bromochloro hydantoin once every 15 days; cultivating of sturgeon over 15 cm length in earth pond, and cultivating in reservoir or lake of sturgeon over gram weight.

Description

Technical field: [0001] The invention relates to a method for cultivating Siberian sturgeon (Acipenser baeri) in plateau saline waters. Background technique [0002] The water quality of saline-alkali waters in the northwestern plateau of my country has a pH of 8.35, a salinity of 1706.61mg / L, an alkalinity of 507.55mg / L, and a hardness of 465.13mg / L. The water type is magnesium sulfate III, which is different from that in central and eastern my country Calcium carbonate II aquaculture water in main sturgeon breeding area. Therefore, in order to breed Siberian sturgeon in the almost barren saline-alkaline waters of the Northwest Plateau, it is necessary to have a breeding technology that is suitable for its ecological conditions. However, there is currently no report on the cultivation of sturgeon in saline-alkali waters on the plateau. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a technique suitable for cul...
