The gills of a fish are lined with many red, blood-rich capillaries called filaments. As water passes over the gills, oxygen is absorbed out of the water through the filaments into the bloodstream.

Inside the gills there is a rich capillary field so that the oxygen is bound to the hemoglobin in the blood an carried back into the heart then onto the rest of the body.

How many species of the perch fish are there?

What are the adaptations of perch?
A few adaptations of perch (really all fish) are the eyes, scales, fins, gills, mucous, etc. (There are a lot!) Eyes- see, Scales- protect from environment, Fins- help fish swim, Gills- breath underwater, Mucous- escape predators fast...
What do fish use to breathe?
Fish breathe through their gills. There are usually gills on either side of the pharynx. Gills have thread-like structures (filaments). These filaments exchange the oxygen and carbon dioxide.
How does fish breath with lungs or with fins?
Neither, in general lungs are only good for animals that breath air and fins are used for swimming not breathing. In a water environment, oxygen exchange is accomplished using organs called "gills" and fish have gills.
Why must there be a continuous flow of water across the gills of fish?
Water must flow with some regularity across the gills of fish for gas exchange to take place. This is essential if the fish is to stay alive. Oxygen is taken from the water by the gills, and carbon dioxide is put into the water. The gills of fish serve essentially the same function as the lungs of people.
What part of a fish is where gas exchange occurs?
The Gills

What gills are?

Where the gills on the perch fish?
Behind the flap of skin that covers them, it is also above the heart.
