Embodiment Construction

[0018] A kind of cultivation method of cultivating Daphnia flying horse with a porcelain jar, the steps are as follows:

[0019] The bait of Daphnia flying horse includes microalgae and bacterial liquid;

[0020] Step 1: Preparation of microalgae as bait for Daphnia fimatis

[0021]The microalgae culture solution is formulated as follows in parts by weight: 0.4 parts of ammonium nitrate, 0.2 parts of ammonium chloride, 0.06 parts of diammonium phosphate, 0.1 part of superphosphate, 0.08 parts of isobutylidene cyclic diurea, and 1.5 parts of sodium bicarbonate , 0.5 parts of potassium sulfate, 0.002 parts of zinc chloride, 0.0001 parts of ammonium molybdate, 0.00001 parts of abscisic acid, 0.03 parts of borax, 0.0004 parts of copper sulfate, 0.1 parts of sodium silicate, 0.00005 parts of Fe-EDTA, 1.2 parts of human urine, boiled 1000 parts of cooled magnetized seawater; take 3 5000ml Erlenmeyer flasks, clean them with a test tube brush, rinse them with distilled water 3 times,...

Abstract

The invention discloses a method for breeding calanus finmarchicus with a procelin jar and belongs to the technical field of aquaculture. In the prior art, an outdoor extensive mode and an indoor intensive mode are used for breeding calanus finmarchicus; an outdoor earth pond mode is low in breeding cost but low in yield, the outdoor earth pond mode is limited by the seasons and water temperature, and the calanus finmarchicus is prone to pollution of viruses and bacteria; the intensive breeding mode is high in yield and scarcely influenced by natural conditions, but the cost is high. Compared with the prior art, the method has the advantages that the porcelain jar is firm, durable, not prone to breakage, convenient to clean and capable of being repeatedly used, operation is convenient, and investment is saved; the calanus finmarchicus is fed with germs, cyclotella, skeletonema costatum and rhombus thalassiosira, the calanus finmarchicus grows rapidly, propagates rapidly and is robust and high in yield, and the limitation of the seasons is avoided.

Description

[0001] Technical Field The present invention belongs to the field of aquaculture, and in particular relates to a method for cultivating Daphnia figas in a porcelain jar. Background technique [0002] Calanus fimarchicus is a small marine copepod zooplankton belonging to Arthropoda phylum Arthropoda, Crustacea Crustacea, Calanus, Calanidae, genus Calanus, body length less than 3mm, camp Planktonic and parasitic life, distributed in warm temperate oceans. Widely distributed in the Bohai Sea, the Yellow Sea and the East China Sea, it is an important bait for economic fish such as herring, mackerel and their larvae, baleen whales, and European North Sea herring. Daphnia figas has been directly harvested in Norwegian coastal waters for decades as food for humans, livestock and poultry, and has high nutritional value. In addition, Daphnia pegasus is closely related to ocean currents, and can be used as an indicator organism for ocean currents and water masses; it can also be used a...
