Description

Annual production system for large-scale culture of plankton such as microalgae

Technical Field

The utility model relates to the technical field of facility agriculture, modern agriculture and high-efficiency agriculture, in particular to an annual production system for culturing planktons such as microalgae on a large scale.

Background

With the development of society and the pursuit of high-quality life by human beings, high-quality aquatic resources are obtained in nature, the huge demands of the market can not be met for a long time, in addition, due to industrial and agricultural pollution, ship leakage, radioactive nuclear wastewater sea-entering events and the like, the potential safety hazard exists in aquatic foods, the modes of culturing various fresh water and seawater aquatic products in facilities have existed for many years, the breeding technology of various aquatic products is gradually mastered by human beings, most of artificially bred aquatic larvae are lack of planktons as opening baits due to the influence of seasonal temperature when being cultured out of season, such as unicellular algae plants (chrysophyceae, chlorella, chaetoceros, diatom, haematococcus, spirulina and the like), bacteria, and zooplanktons (rotifer, brine shrimp, lobster trionyx) with the characteristics of breeding under certain conditions, Chironomid larvae, cladocera, copepods and the like) are used as the bait for aquatic larvae in different development stages, and as plankton is rapid in propagation and growth, rich in nutrition and good in palatability, many scientists at home and abroad research the artificial culture of the bait, but the research has not made a great breakthrough all the time. At present, artificial culture of plankton only needs to be put into some fields and artificial facilities, only some yield is improved within a certain period, and the plankton still can be influenced by seasonal temperature. When large-scale aquaculture is carried out in facilities, such as oyster, shellfish, snail, clam, corbicula and mussel for filter feeding, required plankton baits such as microalgae and the like cannot be met, so far, no ideal substitute baits exist, and a part of bottlenecks encountered by aquaculture in the facilities are in the link of bait shortage, so that the annual production target is difficult to realize. At present, microalgae are used as baits in aquaculture industry, and in other fields such as: the extraction of the biological fuel oil, the fatty acid and the pigment is also widely applied to health-care food, cosmetics, pharmaceutical industry and the like. The cultivation of the microalgae not only needs proper temperature, but also needs certain illumination conditions for photosynthesis, the previous cultivation of the microalgae is completed in a transparent container, when the value is increased in need, the microalgae subjected to multistage cultivation is inoculated into a transparent pipeline reactor for closed cultivation, or is subjected to standing open cultivation in a shallow pool and open cultivation for circular stirring in a runway pool, and the cultivation also belongs to eating by the day, the day and night temperature change fluctuation of the mode is large, the pH value is unstable, the open cultivation is easy to infect other microorganisms to influence the purity, the loss is caused, and the traditional cultivation mode has small water body, low biomass productivity and difficulty in achieving ideal production effect.
