Two methods by which you could remove gases that are dissolved in water are pressure reduction and heating. Pressure reduction uses the fact that the gas follows Henry's Law (amount of dissolved gas in a liquid is proportional to its partial pressure). Reducing pressure makes the dissolved gas less soluble. Heating uses the fact that the higher the temperature becomes, the less a gas dissolves, as long as it does not react with the solvent. Heating can expel gas from a solution.
Evaporate the water, leaving the salt behind.
Not if they are dissolved - if they are then they're of molecular size.
More abundant in water than what? If we presume that you mean to compare the concentration of dissolved nitrogen found in rivers and streams to that dissolved in air, there is only a very small amount, around 1%, dissolved in water but, there is around 79% dissolved in air.
Sure! Some examples of gas solutions include air (a mixture of gases such as oxygen and nitrogen), carbonated water (carbon dioxide gas dissolved in water), natural gas (methane and other gases dissolved in a liquid), hydrogen gas dissolved in water, and oxygen gas dissolved in water.
Although atmospheric air is usually considered a mixture, it is 78% nitrogen, so air could be considered a solution of oxygen, carbon dioxide, and water vapor in nitrogen. These can be removed from air by cooling it and by chemical means. Similarly, helium gas is extracted from a much larger volume of methane (natural gas) with which it becomes mixed beneath the Earth's surface.
It has dissolved oxygen.
Dissolved oxygen can be effectively removed from water through processes like aeration, chemical treatment, and filtration. Aeration involves exposing the water to air, which helps the oxygen to escape. Chemical treatment methods, such as adding sulfur dioxide or sodium sulfite, can also help to remove dissolved oxygen. Filtration through activated carbon or other materials can also be used to remove oxygen from water.

Cloudy water is usually the result of dissolved solids in the water, or dissolved air bubbles in the water.
Although fish and other sea life live in water, they still need oxygen from air to function. They use gills (other something similar) to extract air from the water for respiration. If their was no air dissolved in the water, they would suffocate.
Air is dissolved in water; all gases have some solubility in liquids.
Air provides them with Oxygen - Water provides them with nutrients dissolved from the soil !

Air is mixture of gases. Air can be a solute when is dissolved in water, for ex.
Well, as air is found dissolved in water and fish extract the oxygen of the air, then any gas will dissolve in water. Air also contains a small amount of the Noble gases which are therefore present in the air dissolved in it.
