Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a seawater aquaculture system. Background technique [0002] At present, most of the aquatic products in our country are artificially farmed products, which has brought about the rapid development of freshwater and marine aquaculture industries, and at the same time, many environmental problems have also arisen. In order to maximize the output rate, domestic enterprises often increase the production by increasing the breeding density. Because the density of aquatic products increases the oxygen content of the breeding water, it becomes an urgent problem to be solved. At the same time, the aquaculture wastewater also contains a lot of nitrogen and phosphorus. Hazardous substances, such as harmful substances, lead to the deterioration of the environment of aquaculture waters, increased self-pollution, the trend of eutrophication is becoming more and more serious, red tides occur frequent...

AI Technical Summary

Problems solved by technology

In order to maximize the output rate, domestic enterprises often increase the production by increasing the breeding density. Because the density of aquatic products increases the oxygen content of the breeding water, it becomes an urgent problem to be solved. At the same time, the aquaculture wastewater also contains a lot of nitrogen and phosphorus. Hazardous substances, such as harmful substances, lead to environmental deterioration of aquaculture waters, increased self-pollution, eutrophication trend is becoming more and more serious, red tides occur frequently, fishery drug abuse leads to a series of environmental problems such as drug residues and aquatic product quality and safety.

Even some breeding factories directly discharge the breeding wastewater, and the environmental problems are getting worse

Among them, mariculture is difficult to manage because it is often operated on the seashore, and it is more harmful
