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.
The best known cleaning symbioses are among marine fishes, where several species of small fish, notably of wrasse, are specialised in colour, pattern and behaviour as cleaners, providing a cleaning and ectoparasite removal service to larger, often predatory fish.
Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low. For example, if trout are stocked at 20 kilograms per cubic metre, they can keep the raceway unit clean by their swimming movements, preventing waste solids from settling to the raceway floor.
Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption.
Haller and Hale formed the Canners Machine Co. and allied with the Letson Burpee Co. of Seattle and ran its fish cleaning machines at all of its canneries. Hale was awarded patent 798,334 for his improvements to the machine in 1905, but eventually the design of Edmund Augustine Smith, better known as the "Iron Chink," became the industry standard.
A fish fillet, from the French word filet (pronounced) meaning a thread or strip, is the flesh of a fish which has been cut or sliced away from the bone by cutting lengthwise along one side of the fish parallel to the backbone. In preparation for filleting, any scales on the fish should be removed. The contents of the stomach also need careful ...
Pennsylvania ( / ˌpɛnsɪlˈveɪniə / ⓘ, lit.'Penn's forest country' ), officially the Commonwealth of Pennsylvania [b] ( Pennsylvania Dutch: Pennsylvanie ), [7] is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States.
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.
The ocean sunfish or common mola ( Mola mola) is one of the largest bony fish in the world. It is the type species of the genus Mola, and one of five extant species in the family Molidae. [6] [7] It was once misidentified as the heaviest bony fish, which was actually a different and closely related species of sunfish, Mola alexandrini. [8]
Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species of clownfish are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones.
