I think for specific situations this can be useful. In the final video they show a 'holding tank' the salmon eventually get to and are then hand transported through the building to the next body of water. I think it has been designed for a very specific commercial issue (maximising the restocking of wild salmon). I'm guessing this has applications elsewhere where you want to transport live fish/tubular slimy animals.
