This means that it does not hold back the water and so should have a far lower environmental impact than a barrage. At La Rance there have been ecological changes in the estuary. With tidal stream it is hoped - but not yet proven - that there will be no impact at all. Read the website for the project and you will find it is deliberately sited near very sensitive ecology such as a seal colony. Part of their tests is whether the seals are injured by the blades and whether there are the feared cavitation noises from the blades that affect dolphin sonar. They have undertaken to shut down if they are causing ecological damage. Wish there were more projects which took this responsible attitude. It is a tidal stream turbine, not a tidal barrage.
