Abstract

The invention discloses a high-density culture method for cladocera macrozooplankton. The method comprises the steps as follows: spreading fermented base fertilizer into a first culture pond and theninjecting tap water aerated for 24 h, and starting aeration; culturing bait including chlorella, platymonas and bread yeast in a second culture pond, a third culture pond and a fourth culture pond respectively, and adding corresponding nutritional agents after the tap water aerated for 24 h is injected, wherein in a culturing process, the dissolved oxygen in the first culture pond is 4 mg / L-6 mg / L, the temperature is controlled at 25-28 DEG C, illumination intensity is 5000 lx-8000 lx, and daily illumination time is 8-16 h; opening a valve to add the bait after turbidity of a bait pond reachesa certain value, and closing the valve after turbidity of the bait pond is reduced to a certain value; performing harvesting after turbidity of the bait pond reaches a certain value, and stopping harvesting after turbidity of the bait pond is reduced to a certain value. According to the high-density culture method for cladocera macrozooplankton, the stable growing environment of the cladocera macrozooplankton can be maintained, so that the cladocera macrozooplankton can be stably obtained.

Description

technical field [0001] The invention belongs to the technical field of high-density cultivation of large-scale branched zooplankton, and in particular relates to a high-density cultivation method of large-scale branched zooplankton. Background technique [0002] Macrocladozooplankton is an important part of the water ecosystem and a secondary producer in the biological chain, which plays an important role in maintaining the balance and stability of the water ecosystem. Large-scale cladezooplankton can feed on blue-green algae in eutrophic water bodies, floating debris, and some suspended solids in the water body, which is beneficial to reduce eutrophication of water bodies and improve the transparency of water bodies. At the same time, cladezooplankton themselves Rich in nutrition, it can be used as bait for fish, shrimp and other animals without any harm to the environment. The large cladezooplankton are generally small in size and have a short life cycle, so they are easi...
