Right now, the game can't distinguish between fresh water and salt water. This makes things silly, for example, tuna live in drinking water. My suggestion would be for the game to add fresh water and salt water boats and distinguish between the two. Fresh water vessels can't operate in salt water, as they will rust, and salt water vessels can operate in salt water, but with a reduced capacity due to fresh water weighing less than salt water, producing less buoyancy. This would also open the door to desalination plants. Also, add two fresh water fish to Sunset Harbour- Trout and bass. ALL Winter maps should have fresh and salt water, to allow snowfall players to get the most of this distinction
