Embodiment 1

[0022] A kind of sturgeon breeding method is characterized in that: comprises the following steps:

[0023] Step 1. Select broodstock of Acipenser schrenckii with excellent traits; 1 to 2 years before egg collection / sperm, put the broodstock into the breeding ponds according to gender for rearing in separate ponds; the amount of broodstock feeding is 4-5kg / ㎡; the breeding ponds The bottom is at an inclination angle of 8-12°. The bottom of the breeding pond is paved with 5-6cm thick silt, the silt is covered with a filter, and 2-3cm thick pebbles are laid on the filter; put moss and bitter grass in the breeding pond , river prawns, grass prawns, river prawns, prawns, Guan Gong crabs, portunus and river crabs, the water depth of the breeding pond is 1.8-2m, and the dissolved oxygen is 7-10mg / L; from April to October, the water temperature is kept at 15-18°C, and in other months. The water temperature is 11-14°C; the feed amount is 1-1.5% of the body weight of the broodstock per ...

Embodiment 2

[0026] The only difference between embodiment 2 and embodiment 1 is that the parent fish is Siberian sturgeon.

Abstract

The invention discloses a method for breeding sturgeons, and belongs to the technical field of sturgeons breeding. The method comprises the steps that step 1, sturgeon parent fish with excellent shapes and characters is selected, the parent fish is put into a breeding pond for split-pond breeding 1-2 years before egg / sperm retrieval, sand covers the bottom of the breeding pond, the sand is coveredwith a filter net, cobblestones with the thickness of 2-3 cm are laid on the filter net, and submerged plants and shrimps and crabs are put into the breeding pond; step 2, when gonadogenesis of the parent fish reaches IV period, leuteinizing hormone releasing hormone is adopted to perform drug hasten parturition on the parent fish, the using amount is milter 1.2-1.5 microgram per kilogram and raun 2.5-3 microgram per kilogram, and flowing water is adopted in the breeding pond from one month before drug hasten parturition is conducted to the time when egg cells / sperm are collected; step 3, artificial fecundation is conducted on the collected egg cells / sperm, fertilized eggs are put into an incubator to be incubated until seedlings are produced, and the breeding process is completed. By means of the method, the incubation rate and quality of the sturgeons are improved.

Description

technical field [0001] The invention belongs to the technical field of sturgeon breeding, in particular to a sturgeon breeding method. Background technique [0002] Sturgeon refers to the fish of the order Acipenseriformes, which belongs to the order Osteophytes, Subclass Radiniformes, Order Sclerophyta, and Order Acipenseriformes. Sturgeon is large and grows fast. It not only has important economic values ​​such as food, nutrition, nourishment, health care, medicinal and ornamental, but also has important scientific research value. [0003] With the rapid development of the sturgeon industry, the artificial breeding technology of sturgeon is becoming more and more mature. For example, the Chinese invention patent with the application number CN201110147872.7 discloses a method for the artificial reproduction of sturgeon, but this invention first adopts the observation of physical signs to distinguish the male and female parents, which cannot completely solve the problem tha...
