* this is the conventional argument against using economic exploitation
as a way to control invasive species - once livelihoods depend on the
exploitation there's a clamour to maintain the populations in order to
sustain the livelihoods, and since the species were invasive in the
first place, this management is more likely to be successful than the
management of a native species.
