specific Embodiment approach

[0010] detailed description: The present invention will be further described below in conjunction with specific embodiment:

[0011] 1) Stocking the fry, put the fry in a plastic bag filled with 2-3% salt water for 10-15 minutes for disinfection; then immerse the above plastic bag with the fry at a flow rate of 0.1m 3 / s, the water temperature is 19-23°C, the transparency is greater than 30㎎, the dissolved oxygen is greater than 5㎎ / L, the ammonium ion is less than 0.0125㎎ / L, the pH value is 7.5-8.5, and the nitrite is less than 0.2㎎ / L. , after the water temperature in the plastic bag is close to the pool water temperature, 100-300 hybrid sturgeons / m 2 30-50 Sturgeon Sturgeon / m 2 The density puts the fry into the fish pond whose wall is elliptical and the bottom of the pond is pot-shaped;

[0012] 2) Feeds are fed. Since sturgeons are afraid of strong light, they should be fed in the following manner at a fixed position at dawn or dusk every day after entering the pond: fry ...

Abstract

The invention discloses a sturgeon feeding method, belongs to an aquatic product breeding method, and aims to provide the sturgeon feeding method which is high in survival rate and rapid in growth. The method comprises fry stocking: subjecting fries to disinfection and water temperature adaptability processing before stocking, and then, placing the fries into a fishpond simulating the aquatic environment according to a certain density; feeding: feeding the fries everyday according to timing, regular and quantitative principles; and daily management: performing daily management and disease control according to life habits of sturgeons. According to the sturgeon feeding method, the simulated aquatic environment accordant with natural life habits of sturgeons, a scientific feeding method and a daily management method are adopted, so that effects of whether and human activities on sturgeons in the natural environment are avoided effectively, the survival rate and the growth rate of the sturgeons are improved, and the method is a commercialized sturgeon feeding method.

Description

technical field [0001] The invention relates to a method for cultivating aquatic products, in particular to a method for raising sturgeon. Background technique [0002] Sturgeon is a famous and high-quality treasure in my country, known as "water panda" and "water living fossil". It has high edible, medicinal, ornamental and economic value. Except for the bone plate on the body surface, other parts (including bones) of sturgeon are edible, and have high nutritional value, and are listed as high-grade tonics. Sturgeon has good effects on softening cardiovascular and cerebrovascular, promoting brain development, improving IQ, and preventing senile dementia; cartilage and bone marrow (commonly known as "dragon tendons") contain anti-cancer factors, which are said to be "shark fins, sturgeon bones" ; Therefore, sturgeon has extremely high medicinal value. In addition, sturgeon is a cartilaginous scale fish, which belongs to ancient fish and is known as a living fossil. Becaus...
