Embodiment Construction

[0012] The technical scheme of the present invention is described in detail below in conjunction with specific embodiments:

[0013] 1. Production facilities: Sturgeon fish fry cultivation pool is a flowing pool with an area of ​​0.5-3.0 square meters, a pool depth of 0.2-0.6 meters, a round shape, a smooth bottom, a drain in the middle, and uniform water intake around the bottom wall of the pool. If it is a concrete pool, the bottom should be paved with ceramic tiles, and the fish fry cultivation pool should be constructed or placed indoors (sturgeon water flowers have phototaxis, and gradually become afraid of light as the individual grows), so as to adjust the light. If conditions permit, aeration and oxygenation facilities can be added in the water intake adjustment pool or pool.

[0014] 2. Water quality and water temperature: The basic requirements for water quality of sturgeon fry breeding are: pH6.5~8.0, dissolved oxygen>6.0mg / l, total iron<0.8mg / l, non-ionic ammonia<0...

Abstract

The present invention discloses a technique for making sturgeon fry open mouth and making food-conversion breeding. Said technique is characterized by that according to the different stages of fry growth it can respectively use earthworm segment, whole earthworm and food to raise the sturgeon fry. Said invention also provides the concrete steps of said technique.

Description

technical field [0001] The invention relates to a breeding technology of sturgeon fry, in particular to a breeding technique of opening the mouth and turning to feed the sturgeon fry. Background technique [0002] Sturgeon is the oldest fish with large body and long life among the existing fishes in the world. Sturgeon is an existing ancient biological population, which originated in the Cretaceous period hundreds of millions of years ago, and is known as the "panda" in the water. Sturgeon not only has important scientific research value and special academic significance, but also has high economic value and medicinal value. Sturgeon is a famous and high-quality treasure in my country. It has delicious meat, soft bones and high nutritional value. It is a high-calcium delicious food made of fish bones. It is very beneficial for immunity, improving brain vitality and promoting human health. It is particularly worth mentioning that the sturgeon roe sauce known as "black gold"...
