32 results about "Cleaner fish" patented technology

Cleaner fish are fish that provide a service to other species by removing dead skin and ectoparasites. Although the animal being cleaned typically is another fish, it can also involve aquatic reptiles (sea turtles and marine iguana), mammals (manatees and whales) or octopuses. The cleaning symbiosis is an example of mutualism, an ecological interaction that benefits both parties involved. However, the cleaner fish may sometimes cheat and consume mucus or tissue, thus creating a form of parasitism. A wide variety of fish including wrasse, cichlids, catfish, pipefish, lumpsuckers and gobies display cleaning behaviors. Similar behavior is found in other groups of animals, such as cleaner shrimps.

Self-cleaning fish tank with water treatment function

PendingCN122350023ABacterial virusFiltration
This application discloses a water treatment-enabled, maintenance-free aquarium, including an aquarium rearing area and a treatment device. The treatment device comprises a sedimentation zone, a filtration zone, an ozone oxidation zone, and an ultraviolet photocatalytic zone connected in sequence. The sedimentation zone and the ultraviolet photocatalytic zone are connected to the aquarium rearing area to achieve water circulation. The sedimentation zone is used to treat wastewater from the aquarium rearing area. After sedimentation, the supernatant enters the filtration zone, which removes suspended matter from the supernatant and then transports the filtered water to the ozone oxidation zone. The ozone oxidation zone uses ozone to oxidize at least the organic matter, bacteria, and viruses contained in the water. The ultraviolet photocatalytic zone uses ultraviolet light emitted by an ultraviolet light generator to disinfect the ozone-oxidized water before returning it to the aquarium rearing area. This application provides a technical solution to the problem of "maintenance-free and water quality maintenance" in ornamental aquariums.
