I would just build a salmon ladder on top of the floating pontoon. Just use the sea water and a pump and have it running all the time. Could also design a section of the ladder that is not as high so that maintenance vehicles can still use it. I would also use some technology to count the amount of fish that use it and automatically measure size and height and catalog the fish into a database.
