Morphology

fishway = fish + way (semi-transparent) = fish + way

While 'fish' and 'way' are clear, the specific meaning of a structure aiding fish migration is specialized.

Etymology

The word fishway is simply fish + way, where way means a 'path'. So a fishway is a special 'path' that is built or natural to let fish pass dams or other river barriers and move upstream or downstream.
