Embodiment 1
[0026] a. Disinfect and sterilize the culture container by conventional methods, and the surroundings of the culture container are opaque;
[0027] b. Deploying water for cultivation: detoxify and filter seawater, adjust the pH of seawater to 7-8 with acid and alkali, use electric heating or light to make the temperature 10-15°C, and adjust the salinity to 10-15 with fresh water;
[0028] c. Select species of daphnia: put the collected daphnia tibetan in the culture container described in step a, and cultivate it with the culture water described in step b. Feed the bait such as chaetoceros moowii, and the amount of feeding is 3×10 5 cell / ml, after 1-2 litters of juvenile daphnia have been born, healthy female daphnia with a body length of 2-3 mm and active swimming are selected as seed daphnia;
[0029] d. To cultivate:
[0030] Use the culture container described in step a, and inject the algae liquid of 1 / 5 to 1 / 4 of the volume of the culture container. Produced by one or...
Embodiment 2
[0037]The basic culture method is the same as in Example 1, the culture container of the a step is a 20-251 glass jar or a plastic water tank, soaked in a 10% HCl solution for at least 6 hours, then rinsed with fresh water, the glass jar or plastic water tank Cover it with opaque cloth or paper around it.
Embodiment 3
[0039] The basic cultivation method is the same as that in Example 1 or Example 2. The salinity in step b is obtained by blending nearshore seawater through sand filtration, sedimentation, and 20 μm sieve filtration with tap water after aeration, and aerating for 3 to 5 hours after deployment. . pH can use NaHCO 3 Adjust the pH of diluted seawater with a salinity of 10-15 to 7-8 and the alkalinity to 7-12mmol / l with HCl. It is best to add 0.6-1.0g of NaHCO per liter of water 3 , and then adjust the pH to 7-8 with HCl.
