It's true. Turning liabilities into assets makes a lot of sense.

The "buck law" that came out in the '70's has worked all too well!  Those
who are opposed to all hunting should reflect on winter starvation as an
option.

I hear that young Japanese knotweed is edible.   Haven’t tried it yet.
Something else to look into...

We'd do well do take a similar approach to some booming native species:
porcupines, Canada geese, raccoons...  The problem would be reducing our
efforts when levels drop. Somehow or other, we humans seem a little
reluctant to do that in a timely way.

In a related vein, I worked a couple of summers at the N.S. Department of
Fisheries oyster hatchery (down a long road from Musquodoboit Harbour) in
the early '70's.  Mussel fouling of the oysters was a problem.  Then some
bright soul realized that mussels were edible!  That led to probably the
first investigations into mussel culture along the Atlantic shore of the
province, and the rest is history.

At that time, the only mussels you could get in Halifax came in cans from
Spain or Denmark, and were not very interesting!

(That didn’t solve the fouling problem, but did make use of an abundant
resource!)

I have to give you credit in your strategic thinking and knowledgeable depth
of retrospective!  If only certain departments would manage these fisheries,
they might soon be over-fished and the ecological nightmare created by naive
or selfish sports fisheries could be mitigated somewhat.  Why IS there a bag
limit on any invasive fish??  

Then again, I suppose we could extend this argument to the bag limits for
ring-necked pheasant (noisy squawking birds, though tasty... but not better
than our woodcock and grouse) and the naturalized deer (deer that incur
great damage to our hardwood stands, Canada Yew (with Cancer-fighting
agents), etc, impacting the successional trajectory of our natural forests,
yet we spend a lot of tax dollars managing the herd and bag limits geared to
keep them around).  I'll take a moose steak any day over venison.  

Maybe we can add it to the election platform soon to unfold.  I think we
need an entire ecologically-based political platform in the next round.  Our
natural resources and native biodiversity are in trouble, both on the land
and in the water.  Then there's climate change added to the mix... ecology
is "messy" and growing more complicated.

My point was that if more people recognize pickerel as tasty, more people
will eat them (rather than throwing them back, for instance!).  

I wish NS Fisheries would lift the "bag" limit on smallmouth bass, as well.
They are another disaster that doesn’t belong here.  But here they are.

Enthusiastically-pursued fisheries have a long history of reducing target
populations ...

Oh goodness!  I meant the GEESE are tasty, not than the chain pickerel! No,
no, no! Perhaps the pickerel are tasty, too, but you'll not likely ever hear
me say anything positive with regards to that species.  I am dismayed by the
introduction of chain pickerel to our lakes.  The small mouthed bass and
chain pickerel are altering our fresh water ecosystems in profound ways.  I
am told we can expect nearly "silent springs" as they voraciously consume
our frogs and toads on the lake edges.  They are about to spread to the last
wild places remaining.  It's sad, very sad.  We shall mourn the trout and
remnant salmon populations.

The taste and angling value of the pickerel is high... However its
introduction into watershed has been disasterous.

Back in 1949 Dan Livingstone sampled lakes and rivers in Nova Scotia, coming
up with the first comprehensive list of freshwater fish for the province.
John Gilhen and I were joined by him 50 years later and we re-sampled many
of the same bodies of water.  Where the chain pickerel had been introduced,
or spread to, the diversity of fish went from 7-11 species to 2-3..
independent of water chemistry, geology or any other measurable factor

I wish more Nova Scotians appreciated pickerel.  The Vietnamese gang down
Yarmouth way turns this ugly-looking critter into various dishes, all
infinitely more interesting than haddock!

That's a hilarious (well sort of) tale of the widowed urban goose. She
likely few back to Toronto?

I'm with Lance and the Cape Bretoners. This expanding species is quite
delicious baked in orange juice, wild rice and cranberries, etc.  Now if
only I could acquire a taste for glossy buckthorn salad.

found a very tame single Canada Goose at a boatlunch ramp way north in
Quebec - and the sad story we told was that she'd mated with a northern
Quebec male during the winter, had followed him north, and he'd been taken
out by the spring Goose hunt, leaving her an urban widow in the wilderness.
