Fish wheel: History, Applications & Technology
A fish wheel, also known as a salmon wheel, is a device situated in rivers to catch fish which looks and operates like a watermill. However, in addition to paddles, a fish wheel is outfitted with wire baskets designed to catch and carry fish from the water and into a nearby holding tank. The current of the river presses against the submerged paddles and…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Fish wheel, one of the stronger structural bridges in this analysis connects Fish wheel with Overview. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
