Problems solved by technology

In recent years, due to the commercialization of sturgeon feed, there has been a process of domestication and conversion from fresh bait to artificial compound feed in the breeding process. This process is a turning point for large-scale breeding with commercial materials. Improper feed will lead to extremely low survival rate of sturgeon seedlings and slow growth of sturgeon seedlings

Embodiment 1

[0035] A method for domesticating and changing food of sturgeon fry, comprising the steps of:

[0036] 1. Put the newly hatched sturgeon fry into the domestication pond, keep the water circulation, and dispose of the dirt in time;

[0037] II. When the sturgeon fry sink to the bottom and gather, feed biological bait to maintain water circulation and treat sewage;

[0038] III. When the sturgeon fry grows to 2-3cm, use the first mixed feed to feed, keep the water circulation, and treat the dirt;

[0039] IV. After feeding the first mixed feed for 3-4 days, change to the second mixed feed for feeding, keep the water circulation, and treat the dirt;

[0040] V. After feeding the second mixed feed for 3-4 days, change to the third mixed feed for feeding, keep the water circulation, and handle the dirt;

[0041] VI. After feeding the third mixed feed for 6-8 days, change to using sturgeon fry feed for feeding.

Embodiment 2

[0043] A method for domesticating and changing food of sturgeon fry, comprising the steps of:

[0044] 1. Put the newly hatched sturgeon fry into the acclimatization pond. The density of the sturgeon fry is 5000 / pond. The bottom of the acclimation pond is a downwardly concave arc along the direction of gravity, and the center of the bottom of the acclimation pond is covered with dense mesh. There is a water outlet on the top of the domestication pool, and the water inlet pipe forms an angle α with the direction of gravity, 90°>α>0°. The surface of the water inlet pipe is provided with a water outlet to maintain water circulation. Mountain spring water is the water source, and the water temperature is 16 ℃, the dissolved oxygen is 8.5mg / L, the pH value is 6.5-7.5, the water flow rate is 1.5m / s, and the dirt is treated in time;

[0045] II. When the sturgeon fry sink to the bottom and gather, feed the biological bait, the feeding frequency is 0.8h / time, the ratio of the feeding ...

Embodiment 3

[0054] A method for domesticating and changing food of sturgeon fry, comprising the steps of:

[0055] 1. Put the newly hatched sturgeon fry into the acclimatization pond. The density of the sturgeon fry is 7000 / pond. The bottom of the acclimatization pond is a downwardly concave arc along the direction of gravity, and the center of the bottom of the acclimation pond is covered with dense mesh. There is a water outlet on the top of the domestication pool, and the water inlet pipe forms an angle α with the direction of gravity, 90°>α>0°. The surface of the water inlet pipe is provided with a water outlet to maintain water circulation. Mountain spring water is the water source, and the water temperature is 12 ℃, the dissolved oxygen is 9.6mg / L, the pH value is 6.5-7.5, the water flow rate is 1m / s, and the dirt is treated in time;

[0056] II. When the sturgeon fry sink to the bottom and gather, feed the biological bait, the feeding frequency is 1.2h / time, the ratio of the feedin...

Abstract

The invention discloses a domestication and food conversion method for sturgeon fingerlings. The domestication and food conversion method includes steps of placing the just hatched sturgeon fingerlings in domestication ponds, keeping water circulated and timely treating dirt; feeding the sturgeon fingerlings with biological bait feed when the sturgeon fingerlings sink to bottoms and are gathered, keeping the water circulated and treating the dirt; feeding the sturgeon fingerlings with first mixed feed when sizes of the growing sturgeon fingerlings reach 2-3 cm, keeping the water circulated and treating the dirt; feeding the sturgeon fingerlings with second mixed feed after the sturgeon fingerlings are fed with the first mixed feed for 3-4 days, keeping the water circulated and treating the dirt; feeding the sturgeon fingerlings with third mixed feed after the sturgeon fingerlings are fed with the second mixed feed for 3-4 days, keeping the water circulated and treating the dirt; feeding the sturgeon fingerlings with sturgeon fingerling feed after the sturgeon fingerlings are fed with the third mixed feed for 6-8 days. The domestication and food conversion method has the advantages that the survival rate of the sturgeon fingerlings in domestication and food conversion procedures can be increased, the morbidity probability of the sturgeon fingerlings can be lowered, the rearing cost can be reduced, and growth and development of the sturgeon fingerlings can be promoted.

Description

technical field [0001] The invention relates to the technical field of artificial aquaculture, in particular to a method for acclimating and turning sturgeon fry. Background technique [0002] In taxonomy, sturgeon fishes belong to Osteophytes, Actinopterygii, Sclerophyta, and Sturgeoniformes. They are a kind of ancient creatures with a history of 140 million years. It is a "living fossil" with high nutritional value. The medicinal value of sturgeon is also recorded in detail in "Compendium of Materia Medica": "(Sturgeon) liver is mainly used to treat malignant sores; Deficiency lowers the qi; the seed is like a small bean, eats it for bodybuilding, and kills abdominal worms." [0003] Under the conditions of artificial breeding, the sturgeon seedlings often use water earthworms, and the adult fish use small miscellaneous fish or slaughter by-products as feed sources. In recent years, due to the commercialization of sturgeon feed, there has been a process of domestication...
