Yes, Dam's are built to control inland bodies of water, hence their abilty to contain fresh water.
The salt content. Realistically there isn't a lot of difference since it will always depend on what the fish are eating, so there will be a variety as far as colour and perhaps a bit in consistency.
Mosquito fishes are fresh water fishes.
You will have to get fresh content written by a content writer.

A saltwater fish can't get enough oxygen from fresh water and vice versa. I believe it has something to do with the fact that salt water provides a certain pH balance that they need. Also some fishes can switch back and forth from (salt to fresh or fresh to salt) like the Salmon. Why... probably base on how their bodies evolve so that they can adapt and tolerate such changes. As for other saltwater fishes, if placed in freshwater, the pH balance and oxygen intake will become totally unbalance and end up killing the poor fishes.

If the salt water fish were to be put in fresh water then their high salt content inside their bodies (to prevent too much salt diffusing into their bodies) will have it diffusing out down the concentration gradient; killing them. If the fresh water fish were to be put in salt water then their low salt content inside their bodies (to prevent too much salt diffusing out of their bodies) will have it diffusing in again down the concentration gradient; killing them.
it denpents were the fish is from the ocean or fresh water lakes
