Dear god, that... 'project' is both wrong and awesome at the same time.

I think of using only two water rooms, one with cage traps chains (mermaids are chainable, when captured, arent they?), water filled 4/7.
Second water room would be 1 z-level lower, linked with first through floor hatch. Also, two pumps there, one pumping water in, second pumping out (to airdrown the mermaid babies)
