Not sure how these turbines would interrupt migration patterns. Noise pollution maybe. But that should be smaller than that of a ship engine. They shouldn't kill any macro fauna. It has to be evaluated in practice of course, but sea animals don't travel at speeds where bumping into something is fatal. If they bump into the blades at all, which move a lot slower than a ship propeller.
