Fish ventilation
WebA 2-factorial experiment was conducted to investigate the effect of clay turbidity on ventilation frequency (VF) in juvenile beluga sturgeon Huso huso. Ninety fish (initial mean weight 27.2 ± 0.1 g) were exposed to six levels of turbidity (0.0, 2.5, 5.0, 10.0, 20.0 and 40.0 g clay/l) for three min. WebOct 19, 2024 · Some fish have specialized muscles that allow them to pump the water over their gills. Fish that are very active use a type of ventilation called ram ventilation. Moving forward forces water to move over the gill arches so that oxygen and carbon dioxide can be exchanged. Sharks are a type of fish that use ram ventilation.
