Yes. The fish does not use its mouth to breathe. It uses its gills.
There is o2 in water.
There is not enough Oxygen in the air for the fish to breath. Water has just the right amount of air (O2) that the fish need and in the right proportions. Fish breath in water with gills. Water is capable to holding within it a very large amount of Oxygen. So it is super-concentrated. But the O2 in our air is far less concentrated then in water, so the fish try to gulp the air through and into their gills, but the gills cannot easily find or absorb the O2 from the regular, unpressurized air.
All fish breath through their gills, there is oxygen in water, as such, they take the oxygen through their gills.
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.
The fish hasgills that they use to filter from the water the oxygen they need to as you say "breath" ,so when you put them on land there gills are not working anymore by filtering the water for oxygen because there is no water it's as you know just air (oxygen) so there gills are still trying to work but there is no water to filter oxygen for them.
They don't breath underwater. They can only breath air. (They can hold their breath a long time though.)
Yes. There is usually some dissolved in water. It is what the fish breath.

Fish use gills to extract oxygen from the water to 'breath' .
As any other fish of the water, they use there gills to breath.
Because they are underwater. They have to get oxygen that is dissolved in the water instead of that available in the air. Fish have an air bladder which controls their buoyancy. Some fish can use it as a lung. When they swim in the water they use their gills. When they are on land, they use their lung.
humans only breath in air, and fish only breath in water. so a fish in air would be like you drowning in the water.
because fish have gills and breath in water and we breath air through our lungs
because water is how they breath and air is how we breath. we cannot breath in water so they cannot breath in air.
no
They Die Because They Have Gills and They can´t breath in land,but they can breath in water.
fish breath under water because in water oxygen is mixed.
Fish Can breathe out of water, they just dehydrate quickly and die.
