Problems solved by technology

The Chinese literature "Discussion on Silver Pomfret Domestication Technology" discloses a domestication method for silver pomfret juveniles, which is the result of early experiments and explorations. A large amount of frozen bait is used, and the composition and quality of the bait cannot be controlled. Deterioration is easy, young fish are not active in eating, emaciated, and the survival rate of domestication is low, etc.

Embodiment 1

[0035] From May to June 2016, a scientific research base used this method to domesticate wild silver pomfret seedlings:

[0036] Fish for domestication: wild silver pomfret juveniles caught in the sea, specifications: average fork length: 3.68±0.36cm, average weight: 2.41±0.74g.

[0037] The salinity of the domestication water is 24-29, the pH of the water body is 7.8-8.4, the dissolved oxygen is >7mg / L, the water temperature is 24-28°C, and the inflatable water flow guide plate is installed in the cement pool to maintain the slight water flow, and the water flow speed is 0.1-0.3m / s ; There are sedimentation and filtration devices when the domestication pool enters the water, and the light is 700-2500Lx.

[0038] The compound feed is the special feed for seawater fish produced by Linjian Co., Ltd., the shrimp chips are Shangshun shrimp chips produced by Shantou Yujie Biotechnology Company, and the aquatic product compound multi-dimensional multi-mineral is Jinlukangyu multi-di...

Abstract

The invention relates to a wild pampus argenteus seedling acclimatizing method. The wild pampus argenteus seedling acclimatizing method includes feeding by stages. By means of feeding live baits and mixed feed, eating habits and digestive system of wild pampus argenteus can be changed step by step, batches of juvenile pampus argenteus are prevented from dying from flatulence caused by dyspepsia caused by bait change. The wild pampus argenteus seedling acclimatizing method has the advantages that survival rate and growing speed of artificial cultured pampus argenteus changed from the wild pampus argenteus can be increased effectively.

Description

technical field [0001] The invention belongs to the field of domestication methods for transforming wild fish seedlings into artificial breeding, and in particular relates to a domestication method for wild silver pomfret seedlings. Background technique [0002] Silver pomfret is one of the main marine economic fishes in my country, and it is a new breeding object with great potential in China at present. Due to environmental degradation and overfishing, the germplasm resources of wild silver pomfret have shown obvious signs of decline. In recent years, through continuous exploration and a series of theoretical and practical basic research on silver pomfret breeding and breeding, the full artificial breeding of silver pomfret has been realized. But it has not yet realized its stable and large-scale artificial breeding and breeding promotion technology. At present, the key technical bottleneck restricting the large-scale artificial breeding and breeding of silver pomfret is...
