A structure built to help fish swim past obstacles like dams or waterfalls in a river.
The construction of a fishway allows salmon to reach their spawning grounds upstream.
Fishway → The word is formed from "fish" (from Old English *fisc*, meaning a gill-bearing aquatic vertebrate) and "way" (from Old English *weg*, meaning a path or route). A fishway is a constructed path or route that allows fish to navigate around obstacles in water bodies.
Think of a 'path' ('way') designed specifically for 'fish' — that's what a fishway is, a route for fish to travel.
