Hmm. Aren’t the Great Lakes in North America connected to each other and then to the St. Lawrence River via Lake Ontario, which eventually leads to the Atlantic Ocean? Maybe the map should include those large bodies of water too.
There are fish that go from saltwater to freshwater or vice versa. They’re called anadromous fish. Salmon are one species like that. So you’ll have to include every river as well.
Lampreys are the greatest explorers among saltwater fish. They’ve mapped most of deepest darkest Greatlakesica, but most don’t make it back out to report their findings.

How do biologists determine that the lampreys migrated from the ocean versus being hatched/born in the Great Lakes?
Accent. You can take the fish out of the ocean but you can’t take the ocean out of the fish.
