Description

TECHNICAL FIELD

[0001] The utility model belongs to the aquaculture technical field, concretely relates to a system for indoor continuous culture of monogolica. BACKGROUND

[0002] Monogolica belongs to cladocera, and is a kind of monogolica special in salt water, can complete life cycle through parthenogenesis in the salinity range of 2-50.Monogolica has the characteristics of wide salinity adaptation, rapid reproduction and easy high-density culture, and as biological bait, monogolica is nutritious, can meet the nutritional needs of aquatic animals, and according to the needs of different breeding objects, provides different sizes of biological bait to meet the specific needs of aquatic animals in different growth stages.Most aquatic animals like to eat biological bait, and it is easy to digest, contains digestive enzymes, and can make up for the lack of digestive capacity of juvenile.These advantages make monogolica become an ideal biological bait in mariculture and crustacean culture.

[0003] But the current monogolica culture mostly adopts the external pond culture mode, and the water quality management is difficult, and the water quality of external pond is easily affected by external factors, such as pollutants brought by rainwater, fertilizer and pesticide runoff of surrounding farmland and industrial wastewater, resulting in unstable water quality, which is not conducive to the growth and reproduction of monogolica.For example, excessive nitrogen, phosphorus and other nutrients may cause water eutrophication, excessive growth of algae, and affect the living space and oxygen supply of monogolica.The pH value of water quality fluctuates greatly, which exceeds the suitable growth range of monogolica, resulting in pond reversal and affecting its physiological function.

[0004] In addition, there may be various enemy organisms in the external pond, such as fish, insect larvae, hydra, etc., which can prey on monogolica, causing the population of monogolica to decrease.Some small fish, such as Pseudorasbora parva, may eat a large number of monogolica larvae.The water temperature of open-air external pond is significantly affected by season and weather.Extreme high or low temperature will have adverse effects on the survival and reproduction of monogolica.In hot summer, high water temperature may cause metabolic disorder of monogolica, and even death;while in winter, low water temperature may make cladocera enter dormancy and slow down reproduction. CONTENT OF THE UTILITY MODEL

[0005] To address the aforementioned technical problems, this utility model discloses a system for continuous indoor culture of *Neuroceras mongholicus*. This system changes the cultivation of *Neuroceras mongholicus* from outdoor to indoor environmentally controlled culture, removing external influences such as predators, temperature changes, and competitors. A composite system is created to filter *Neuroceras mongholicus* feces. Utilizing a powerful filtration system combined with an airlift system, the airlift system significantly agitates the water, filtering out the feces of the heavier *Neuroceras mongholicus* immediately, preventing sedimentation and maintaining a clean culture water. A powerful circulating water system further reduces ammonia and nitrite levels in the water. The treated, high-quality water is then returned to the culture tanks, achieving water recycling. The high-quality water allows *Neuroceras mongholicus* to grow in a comfortable environment, significantly reducing the chance of mortality. Furthermore, this circulating culture system can also solve most of the difficulties encountered in outdoor pond culture of cladocerans.

The system uses an enlarged filter area and air stripping to filter the feces and carcasses of Mongolian Lecane on the filter medium. Compressed gas enters seawater through a bubble generator to form a large number of bubbles. The bubbles form a negative pressure environment during the rising process, driving seawater and the feces and carcasses of Mongolian Lecane to rise along the reflux pipe and enter the filter device. The filter medium intercepts the feces of Mongolian Lecane. The seawater after the first filtration enters the horizontal micro-filter to filter out suspended matter, and then enters the protein separator to discharge the protein dissolved in the water to the biochemical pool for ammonia nitrogen and sub-salt treatment and sterilization, and finally enters the culture container for recycling.
