As you may know, fish in saltwater will lose water, and gain salt due to diffusion.

When there is a higher concentration of salt outside the cell than inside, the salt automatically moves into the cell. The fishes in saltwater then have to drink water all the time and filter out the salt to the urine, so that they keep themselves hydrated.
