Problems solved by technology

However, there is always a problem in the high-density cultivation of algae, which is to replenish carbon dioxide in time to remove excess oxygen; and the cultivation of zooplankton is just the opposite, it needs to replenish oxygen in time to remove excess carbon dioxide

Embodiment

[0023] 1. Fabrication of algae-zooplankton linkage culture device

[0024] 1) Production of culture tank

[0025] The cultivation buckets include an algae cultivation bucket 1 and a zooplankton cultivation bucket 2 . The algae cultivation barrel 1 is barrel-shaped, with a diameter of 30 cm and a height of 80 cm; wherein, the height of the culture solution part is 60 cm, and the height of the lower part is 20 cm, with a built-in magnetic particle stirrer 9 . Its top is a circular upper cover, which is connected to the barrel body by adhesive to achieve the sealing effect; a small hole with a diameter of 2 cm is left on the upper cover at a distance of 5 cm from the edge, and a hollow cylinder with a height of 5 cm is connected outside for connection The nutrient solution is introduced into the tube 7. The zooplankton culture tank 2 is barrel-shaped, with a diameter of 50cm and a height of 20cm; its top is a circular loam cake, which is connected with the barrel body by an adh...

Abstract

The invention relates to an alga and zooplankton linkage culturing device, belonging to the technical field of culture of food organisms in aquatic seedlings. The device comprises an alga culturing bucket, a zooplankton culturing bucket, a nutrient solution reserving tank, a sterilizer, a connecting component, auxiliary components and the like, wherein gas exchange can be carried out between the alga culturing bucket and the zooplankton culturing bucket, and alga solutions can be injected into the alga culturing bucket and the zooplankton culturing bucket. The invention perfectly solves the problem that saturated oxygen gas in the unicellular alga culturing process and surplus carbon dioxide in the zooplankton culturing process have inhibiting effect on cultures, so that the two kinds of biological feed can mutually utilize wastes generated by the opposite side. The device of the invention can be used for simultaneously culturing the two kinds of biological feed with high density, simultaneously reduces the labor cost and the material cost in the process of independently culturing one kind of feed with high density under the general condition, and can be widely applied and popularized to the field of culture of aquatic seedling feed.

Description

technical field [0001] The invention belongs to the technical field of bait biological cultivation in aquatic seedling cultivation, and in particular relates to a linkage cultivation device for algae and zooplankton baits. Background technique [0002] At present, there are many studies on the cultivation of algae and zooplankton at home and abroad, such as the primary, secondary and expanded cultivation of algae monoculture, and many effective operation methods have been formed. The research on monoculture of zooplankton has also made great progress, especially Japan has made significant progress in the high-density cultivation of rotifers in factories. However, there is always a problem in the high-density cultivation of algae, which is to replenish carbon dioxide in time to remove excess oxygen; and the cultivation of zooplankton is just the opposite, it needs to replenish oxygen in time to remove excess carbon dioxide. Therefore, the culture of algae and rotifers in the...
