Water transmits stimuli differently than air, leading to specialized sensory organs.
Be able to trace a drop of blood from the Sinus Venosus through to the Ventral Aorta. Fish Physiology Notes
Cardiac output (CO) is determined by stroke volume and heart rate. In fish, stroke volume is generally considered more important for increasing output than heart rate. Because the blood passes through the fine capillaries of the gills before going to the body, there is a significant pressure drop, limiting the metabolic rate compared to warm-blooded animals. Water transmits stimuli differently than air, leading to
Whether you are preparing for an ichthyology final, setting up a recirculating aquaculture system, or simply fascinated by what swims beneath the surface, mastering these physiological principles is key to understanding how fish function, adapt, and survive. In fish, stroke volume is generally considered more
