Adesalination plant is set up in a bay to provide fresh, drinkable water by removing salt from ocean water and returning the removed salt to the bay. how might the resulting increase in salinity in the bay affect the fish populations?

Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
