Description

Technical Field

[0001] The invention relates to the technical field of black sea bream breeding, and in particular to a biological decontamination device for black sea bream breeding. Background Art

[0002] As aquaculture continues to expand and production surges, a series of ecological and environmental problems have gradually emerged. Leftover bait, debris, and fish and shrimp excrement generated during aquaculture contribute to pollution within the aquaculture system itself. This is particularly true with the intensification of aquaculture practices, which has led to significant increases in stocking density and feeding rates, as well as corresponding increases in leftover bait and fish excrement, making aquaculture pollution even more severe.

[0003] Discharge of aquaculture tailwater pollutes the surrounding waters, wasting water resources. Fishing drugs, leftover bait, debris, and fish and shrimp excrement can also increase the levels of heavy metals such as nitrogen and phosphorus in the water. Viruses, bacteria, and other microorganisms can accumulate in the water, reducing the water's self-purification capacity and leading to eutrophication or deterioration of water quality. This can, to a certain extent, cause toxic contamination to farmed animals, further impacting both human consumption and the ecological balance of aquatic animals. To address this issue, we have developed a bioremediation device for black sea bream aquaculture. Summary of the Invention
