Fish Wheelswere so effective and therefore banned in the United States because they threatened the salmon population
A fish wheel is a water-powered device used for catching fish, particularly salmon. Their design was simple: it consists of a revolving wheel with baskets and paddles attached to its rim. The wheel rotates due to the current of the stream pressing the bottom basket or paddle that has swung down into the water.
When the wheel is floated on the river, the river current turns the wheel causing the baskets to scoop down upon the salmon traveling upstream and lift them out of the water. The ingenious device can catch large amounts of fish, and the best part is that the fishermen don’t even have to be there. A holding tank is placed beside the wheel to receive the falling fish. A harvester need only come by only a few times each day to remove and process caught fish from the holding tank.
