Cleaner fish. Cleaner fish are fish that show a specialist feeding strategy [ 1 ] by providing a service to other species, referred to as clients, [ 2 ] by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. [ 2 ] This example of cleaning symbiosis represents mutualism and cooperation behaviour, [ 3 ] an ...
Aquatic feeding mechanisms. Grouper capture their prey by sucking them into their mouths. Aquatic feeding mechanisms face a special difficulty as compared to feeding on land, because the density of water is about the same as that of the prey, so the prey tends to be pushed away when the mouth is closed. This problem was first identified by ...
Filter feeders can play an important role in condensing biomass and removing excess nutrients (such as nitrogen and phosphate) from the local waterbody, and are therefore considered water-cleaning ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. Filter feeders can be sessile, planktonic ...

A raceway, also known as a flow-through system, is an artificial channel used in aquaculture to culture aquatic organisms. Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet.
The bigmouth buffalo (Ictiobus cyprinellus) is a fish native to North America that is in decline. [2][3][4][5][6] It is the largest North American species in the Catostomidae or "sucker" family, and is one of the longest-lived and latest-maturing freshwater fishes, capable of living 127 years and reproducing infrequently. [4][5][3][6] Even at a ...
