Problems solved by technology

However, because the content of the research is not comprehensive and in-depth, there are still big problems in some links, such as the breeding method of the spoon-kissed sturgeon larvae, which makes the spoon-kissed sturgeon have low survival rate, unscientific feeding, and more bait loss and waste during the breeding and breeding process. Many deficiencies and defects such as increased cultivation costs

Embodiment Construction

[0006] The following example is described in detail about the method for cultivating the spoon-kissed sturgeon.

[0007] 1. Cultivation method of spoonbill sturgeon seedlings: the area of ​​the pond for larvae cultivation is 2.5m 2 , Circular fiberglass cultivation pool with water depth of 0.4m. During the breeding period of larvae, the stocking density is first and then 6000-2000 fish / m 3 , with 1 / 3 larvae tied as a sign of opening, and the bait for opening is Brachiacus rotifer. For the first 3 days after opening, feed Brachionus rotifer every 2 hours, and the live bait in the cultivation pool should not be less than 120 / ml , for the next 4 days, feed small naked-bellied fleas once every 3 hours, and the live bait in the cultivation pond should not be less than 80 / ml. From the 8th day after opening, feed medium-sized naked-bellied fleas once every 4 hours , The live bait in the larvae breeding pond should not be less than 40 / ml. The area of ​​the cement pond for juvenile ...

Abstract

The breeding process of polyodon spathula belongs to the field of aquatic raising technology. The breeding process includes throwing rotifer and euglena as feed with the cultivation density of 2000-6000 / cu m for fry polyodon spathula and 400-1100 / cu m for small polyodon spathula. The breeding process has high survival rate, high utilization of feed and low cultivation cost.

Description

technical field [0001] The invention belongs to aquaculture technology, and mainly relates to a method for cultivating spoonbis sturgeon. Background technique [0002] The fishery species structure of ponds, lakes, reservoirs, etc. in our country is fixed and single, and the problem of low fishery economic benefits has been going on for many years. Therefore, for many years, workers in the fishery field have worked hard to find species structures that are conducive to adjusting fisheries such as ponds, lakes, and reservoirs. And improve the fishery ecosystem, so that the fishery resources can be gradually optimized. The sturgeon belongs to the family Acipenseridae and is native to North America. Spoon-nose sturgeon has the characteristics of wide temperature range, fast growth, wide source of bait, no damage to the water environment, low production cost, easy fishing and high economic value. Since the Hubei Provincial Fisheries Bureau introduced the breeding of the sturgeo...
