Rotenone cause fishes to suffocate by preventing them from taking oxygen, so
there's no actual poison in the fish affecting its eating quality.

I don't know how it kills terrestrial insects when used as a pesticide, but
I wonder if the insecticide properties is the benefit the plant receives
from having such a toxic compound in its bark.
