For the record:
The correct spelling is catadromous. Fish that grow to adulthood in fresh water, breed in salt. Yes, they can make it to the Sargasso. Atlantic salmon go from CT and other places in New England to the Labrador Strait off Greenland to grow out, return here to spawn (those very few that now make it). Used to be 40,000 or so in CT River system alone, before the dams. Stripers go from Maine (maybe some from Nova Scotia) to the Chesapeake. Herring from Bay of Fundy to Carolinas and Florida. Why not?
American eels and European eels are thought to breed in the Sargasso. They float along the Gulf Stream as larvae. American eels develop faster, move inland to fresh water. Europeans develop more slowly, travel farther before moving inland in Europe.
Eels can be found in inland ponds, they can travel short distances over wet grass between bodies of water. They can also get around dams this way.
Aquacultured eels are only profitable if sale prices are high. You have to be able to pay for your aquaculture systems, electricity, labor, feed, antibiotics,... Probably not going to profit much at the $1 you can get for them in bait shops. The Japanese raise them for food, get $$$ per pound. I don't want to shuck out that much for bait, either do you.
Correct that eels won't breed in Fresh water.
