Fish gills are the equivalent of human lungs.
Our lungs, and the fish's gills, are the part of the body that absorb the oxygen we need and expel the carbon dioxide that we nave to get rid of. The way that this happens is through the blood vessels (arteries carry oxygen-rich blood around the body, while veins carry deoxygenated blood)
Humans extract oxygen from the air that they breathe into their lungs, while fish obtain their oxygen from the water that passes through their gills.

What evidence is there of rich blood supply in the gills of a perch?
If there is a good blood supply to the gills of a fish it will be breathing and acting normally. As all fish are quite different this will have to be compared to an average happily living fish of the same br The red color of gills is from hemoglobin. Also, think about the size of the gills relative to the overall size that different fish can achieve it also stands to reason that sufficient oxygen must be transported to all the tissues via blood...as well as any expiration gases hence the gills have massive amounts of blood.
Is a tiger a fish?
