ositive with regards to that species.&amp;
CPs have a bit of edge there.  They can tolerate up to about 15ppt salinity, so have been suspected to move in near-shore estuarine waters during spring and fall freshets

Well Peter the difference is in my limited view
is that Browns and Rainbows spread via salt water
and CP are unable to do this. Browns have been reported
from PEI where they were never introduced. Rainbows
on PEI took about 50 years to make an impact from
an angling view. So we can expect both to spread
slowly but surely. CP on the other hand are like a grass
fire in the spring. They take up every corner quickly!
The angling regulations in NS don't favor the fishing of
either Browns or Rainbows. Night time and salt water
are prime times for sport fishing either and both come into
fresh water late in the year and leave early.
So I suspect the total numbers of either is under estimated.
But the laws are made by 9 - 5 ers so I guess that wouldn't change!
But what do I know but I e njoy the spring
Hope you do too!

I always find it interesting that the chain pickerel comes up often as an invasive species but I have yet to see any complaints or comments on brown trout.

I have to give you credit in your strategic thinking and knowledgeable depth

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.
