In the seedling stage of many farmed animals, especially crustaceans and shellfish, unicellular algae are the main starter bait, and can even determine the success or failure of seedling cultivation. Feeding live unicellular algae bait in the production of aquatic seedlings can not only fully meet the nutritional needs of aquatic animals, but also increase the dissolved oxygen content in the water, reduce ammonia nitrogen, balance water quality, inhibit the growth and reproduction of certain pathogens, and reduce the occurrence of diseases. Microalgae DHA extracted from marine microalgae is easy to absorb and is very suitable for pregnant women, breastfeeding mothers and infants. It is beneficial to the normal development of the brain and visual system of the fetus and infants.

[0003] In the prior art, the inventors have found that the existing microalgae cultivation technology has at least the following problems:

[0004] (1) In the process of using the existing device, it is very inconvenient to add disinfected seawater, add algae seeds, and add oxygen. It is also difficult to release the cultured bait and it is impossible to clean up the dead algae that sink to the bottom in time;

[0005] (2) During the cultivation process of marine microalgae, supplementary light is required for the marine microalgae. However, the position of the light source cannot be adjusted in the existing device (the supplementary light is not reflected). Utility Model Content
