A cleaning station is a location where aquatic life congregate to be cleaned by smaller beings. Such stations exist in both freshwater and marine environments, and are used by animals including fish, sea turtles and hippos.
Cleaning symbiosis is known from several groups of animals both in the sea and on land (see table). Cleaners include fish, shrimps and birds; clients include a much wider range of fish, marine reptiles including turtles and iguanas, octopus, whales, and terrestrial mammals.
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]
With 1,100 linear feet of space, the pier also provides covered platforms for protection from the elements, a fish-cleaning table, and some of the best angling in the state.
There are two types of cleaner fish, obligate full time cleaners and facultative part time cleaners where different strategies occur based on resources and local abundance of fish. Cleaning behaviour takes place in pelagic waters as well as designated locations called cleaner stations.
In addition to washing dishes and preparing foods for roasting and boiling, such as cleaning vegetables and dressing poultry, game, and fish, the scullery was used for boiling water and doing laundry, which necessitated the following equipment: Set pot (the "copper" or a big metal tub): boiling water; Dolly tub: soaking dirty clothes overnight
In a well designed system, the existing water in the raceway is largely replaced by new water when the same volume of new water enters the raceway. Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low.
I've seen a cleaning action with only one fish being cleaned, but this one was really a cleaning station with many fishes lined up to get cleaned. So, cut fishes in the left (convict tangs) and a fish behind the corals, as well as the corals themselves are part of the subject.
Cleaner shrimp are so called because they exhibit a cleaning symbiosis with client fish where the shrimp clean parasites from the fish. The fish benefit by having parasites removed from them, and the shrimp gain the nutritional value of the parasites.
Hypostomus plecostomus is one of many species of fish that is able to breathe air. Hypostomus plecostomus relies on its gills for respiration in normal and slightly hypoxic water, and the less oxygen present in the water, the more frequently it surfaces to breathe air.
