This page started with an amusing name, and just kept getting wilder. 182 million fish per year were expected to die without any protection -- an incredible number, almost 6 fish per second. So now I think "Yes! By all means add some ultrasonic speakers to keep them out!" And then I learn that these speakers will cost £50m... As a part of £700m in total fish protection measures! And that somehow Natural England finds that to be be insufficient!?

I feel like every fish on the Welsh coast could have its own personal concierge for that price.

Seems like a good idea, since smacks of jellyfish have been known to shut down power plants.
