I don't even understand what "controls" means here? Are you talking about turning the Suez Canal into a filtered lock system able to hold Suezmax class ships (160,000 DWT)? Wouldn't the massive energy usage by pumping/filtering that much water (and the usage by the ship's idle engines while they wait) do more environmental damage than the invasive species?

Obviously the correct engineering solution is underwater laser turrets. Mounted on sharks.
We use electrified barriers to prevent Asian carp spread in the Great Lakes region [0]. I'm not sure of the practicality of something similar in a saltwater canal.

I was thinking of a filtered lock system, and you're right that that's impractical for the Suez.
> A first look at some groups of exotic species shows that more than 70% of the non-indigenous decapods and about 63% of the exotic fishes occurring in the Mediterranean are of Indo-Pacific origin, introduced into the Mediterranean through the Suez Canal. This makes the Canal the first pathway of arrival of alien species into the Mediterranean.
