No, a flying fish does not undergo a chemical change simply by flying. Chemical changes involve the formation of new substances with different chemical properties, which is not the case when a flying fish flies out of water.
The refraction of rays of light as they leave the water will cause the fish to appear in a different position i.e further away and closer to the surface. In order to spear the fish the fisherman will have to aim slightly in front of the apparent position of the fish.

Some fish such as cichlids will change color as they mature. Another reason for fish to change color is stress. When fish stress out they can loose almost all of the color until they calm down.
Grilling a piece of fish involves both chemical and physical changes. The physical change occurs when the fish is heated by the grill, causing it to cook and change texture. The chemical change occurs when the proteins in the fish denature and the Maillard reaction occurs, giving it a different flavor.

It depends on what type of fish change colors, like for example a black moor fish can change color by its temperature.
