Problems solved by technology

In addition, in the research of marine ecology, a problem that has always plagued the research of marine copepods in my country is that there is no indoor experimental population of copepods, and live experiments can only be obtained through fishing. The progress of work is greatly affected by natural environmental conditions and natural population changes. Impact

Embodiment Construction

[0011] With reference to accompanying drawing and embodiment, the present invention is described further:

[0012] 1 in the figure is an incubator, the lower part of the incubator 1 is connected with the water quality adjustment tank 11, the outer wall of the incubator 1 is equipped with a return pipe 2, the upper end of the return pipe 2 is connected with the incubator 1, and the lower end of the return pipe 2 is placed in the water quality adjustment tank 11 , the return pipe 2 can be installed with 4, 6, 8, etc., preferably 6, installed symmetrically and evenly, which can greatly reduce the eddy current intensity at the mouth of each pipe, and can avoid unidirectional water flow at the top of the incubator 1 . Pump 9 is installed in the water quality adjustment box 11, and this pump 9 can adopt submersible pump etc. The pump 9 is connected with the incubator 1 through the water pipe 7, and the water pipe 7 is connected with one end of the oviduct 12, and the other end of t...

Abstract

The invention discloses an apparatus for trainring copepods species in-doors, including a incubator, the lower part of which connects to a water quality regulating tank, a reflux pipe arranged on the outer wall of the incubator, and the upper part of which communicates with the upper part of the incubator, while the lower part is positioned inside the water quality regulating tank, whereof a pump is fixed inside; the pump connected to the incubator by a water pump, which linked to an end of a taking-off ovum tube, while the other end of the taking-off ovum tube arranged outside of the water quality regulating tank,; the top of the incubator as open type; the bottom of the water quality regulating tank lied an fall tube. The apparatus applied to mass propagate copepods species in-doors, so as to simplify the training method, decrease the cost, and improve the efficiency.

Description

technical field [0001] The invention relates to aquaculture equipment, in particular to an indoor culture device for copepod populations. Background technique [0002] At present, in aquaculture, finding suitable bait for larvae and reducing population mortality during the critical period of feeding is an important issue that the aquaculture industry of all countries pays close attention to. Many research institutions in the world are working on mass production of copepods in order to achieve the purpose of commercialization. Compared with rotifers and artemia, which are commonly used as open baits in mariculture, copepods have higher nutritional value. Copepods mainly feed on phytoplankton, and also eat a small amount of animal bait. They store a large amount of nutrients in their bodies and are rich in fatty acids and amino acids. The most attractive thing is that copepods contain high levels of highly unsaturated fatty acids, etc. , and when fish are cultured with rotif...
