Absorption of oxygen through the gills via osmosis. Since the membrane of the gills is so thin, the oxygen can pass through into the bloodstream. It is a passive form of respiration.

Water flows over the gills which have lots of blood vessels running through them. The oxygen gets absorbed through into the cells and the water just flows out.

Okay, so in a fish's gills the blood runs through it and it touches the water and stuff when they open up, and the oxygen in the water gets into their blood stream.

Their gills filter the water to extract all the oxygen out of the water.

gills that are made up of cells that filter out the oxygen atoms.

Silly they don't breathe. The water goes in the gills sort of like a filtering system that grabs what they need to survive.
