Problems solved by technology
[0002] Due to the limitation of environmental pollution, water and land and other resources, the production of aquaculture seed has brought severe challenges and become a bottleneck for the development of aquaculture industry.
The amount of industrial wastewater and domestic sewage directly discharged into the river and sea has seriously polluted the aquaculture waters, causing the concentration of inorganic nitrogen in the waters to exceed the standard, and the increase in the content of active phosphate, COD and heavy metals has seriously affected the growth of aquaculture fry.
At the same time, due to the metabolism of fish, the accumulation of residual bait and the excessive use of various chemicals, the pollution of aquaculture itself affects the healthy growth of fry.

A closed aquaculture seedling cultivation system, the invention relates to an aquaculture seedling cultivation system. The invention consists of two parts: a hatching workshop and a seed cultivation workshop, and is characterized in that the seed cultivation workshop is arranged with a controlled circulating water seed cultivation system, the hatching water in the hatching workshop is drawn from an outdoor water tower, and the hatching water for fish eggs enters the hatching barrel from the lower end. The sewage in the hatching tank flows out and collects through the upper end, and then is discharged into the outdoor oxidation pond through the sewage pipe for centralized treatment; each set of circulating water seedling cultivation device consists of a circular glass fiber reinforced plastic tank, a tank liquid level controller, a pressure filter, a buffer tank, and a circulating water pump. , Biological filter, gas-liquid deep mixer, integrated constant temperature machine, pH automatic control system, electrical control system.
