Description

Technical Field

[0001] This invention belongs to the field of aquaculture equipment technology, and particularly relates to an automatic algae removal device for aquaculture ponds. Background Technology

[0002] Currently, during the sunny summer months, aquaculture ponds often experience high algae densities. Due to rapid metabolism during high temperatures, if nutrient replenishment is not timely or balanced, large amounts of algae age and die daily. The decomposition of dead algae consumes a large amount of oxygen and produces toxic substances such as hydrogen sulfide, which can lead to poisoning and death in farmed animals in severe cases. Prolonged excessive algae growth can raise the pond water pH to 9-10, causing low dissolved oxygen or even hypoxia at night, leading to oxygen deprivation, fish surfacing, or suffocation. It also reduces the immunity of farmed animals, creating conditions for the outbreak of other diseases. Furthermore, the algal toxins produced by algae not only inhibit the growth and reproduction of other beneficial algae but also cause algal toxin poisoning in farmed animals, inducing disease. Therefore, for the above reasons, timely removal of excess or dead algae is crucial.
