What do Pharyngeal pouches become in Fish?
gill slits
How can water be brought to the gills when the mouth is closed?
The gills have external slits that bring water two the gills. A fish can draw water in through it's mouth, but when the mouth is closed, these slits cycle water past them.

Do crocodile have any rudimentary gills because they were evolved by a fish named tiktaalik?
Regardless of the presumed relationship to tiktaalik, you will find gill slits to be present in all vertebrates. In reptiles, the slits would not persist past the embryonic stage but, the crocodiles' jaws were derived from the gill arches. Look up "Ontogeny recapitulates phylogeny."
What organs do most fish breathe with?
Gills provide means of respiration for most fishes. Gills function very similar to that of our lungs. Pharyngeal gill slits usually help to filter out waste particles during breathing in of the water.

Do fish breathe?
They extract oxygen from the water using gills. Pumping water through the gills is called respiration, and is basically like breathing. So yes, fish breathe, they just don't usually breathe air. Some fish however, such as the lung fish, breathe (gulp) air from the surface. Fish breathe through organs called "gills" which are located on both sides of their heads. Gills are just like the lungs of land animals, but adapted slightly to enable the fish to breathe underwater. Fish breathe by gulping water. The water brushes over the gills of the fish. The gills then extract the oxygen out of the water and replace it for carbon dioxide. Then the water passes out of the slits/gills on the side of the fishes head. Gills are very effective at their jobs. They can extract 80% of the waters oxygen in every gulp. Gills are specifically evolved uniquely for the species of the actual fish. For example, a saltwater/ocean fish needs stronger gills to extract oxygen from the harsh, salty water. Whereas freshwater/river fish have less stronger gills, because they don't have an issue with salty water. This is also why freshwater fish cannot survive in the ocean.
