Yes fish have organs. Every single multicellular organism has organs.

If your reffering to " What are the organs of a fish?" then the answers is; They have a liver They have a stomach They have an eye they have a brain They have gills. And yes, gills are organs.
i think wings
the brain
the movement of the fish is because of its bones and/or spine.
The lateral line is a system of sense organs; neuromasts situated along/in the lateral line detect movement and vibration in water. The system is important in schooling and predatory behaviour, as well as in general for spatial awareness. It allows detection of movement outside of the range of vision, or in conditions that reduce visibility. Blind fish will orientate towards movement in the same way as fish that are able to see, but disruption of the lateral line also disrupts the response to movement.
