even if it does, all they have to do is just keep swimming

> Could this disrupt the migrations of species like clown fish and sea turtles?

Not, cute cartoons are safe and will live to suffer a sequel. Nemo is now a girl.

But will disrupt the migrations of real animals that are endangered, like sharks, eels (most vanished in the last 60 years) and mesopelagic squids and fishes that play main roles in fighting human famine.

And the technology will need to find a way avoid getting cluttered by marine snow and filterers settling on it, most probably.

I was also wondering about this and it got me thinking - I'd the turbines would be spinning fairly slowly, and I'm picturing some sort of filtering device behind them that could filter plastics or other pollutants to the ocean. In an ideal setup maybe it can filter stuff out and use that to create more energy

Maybe also not what we want, but it could be cool to see if some new ecosystems set up around these structures

Filtering, eh?

You volunteering to change the filters? By definition, that's a maintenance task.

I wanted to say clown fish don't migrate, but apparently they do..

Those turbines probably move very slowly. Hard to hit or hurt anything at those speeds in the water. Sea life will be more trouble for the turbines than the turbines will be for the Sea life. Noise pollution may be an issue.
