 SH> My SIL has called the number.  He's getting worried.  The
 SH> game people were walking the local creak the other day after his
 SH> call.

There are none in Lake Ontario yet. He is catching regular common
carp.


"They have migrated north through U.S. waterways towards the Great
Lakes. Preventing Asian carps from spreading into the Great Lakes is
the best way to prevent harm to Ontario's native fish species and
our ecosystems.

Asian carps (Silver Carp, Bighead Carp, Grass Carp, Black Carp) have
replaced native species in areas of the Mississippi River and its
tributaries.

Make up more than 50 per cent of the fish by weight in some parts of
the Illinois River are now Asian carps.

They consume up to 40 per cent of their body weight each day of
their respective diets, which leaves little food for native fishes
to eat.

Can grow more than 25 cm in their first year., quickly outgrowing
the 'gape' (mouth) size of any would-be predators in our waters
(e.g. Muskellunge, Northern Pike, etc.).

Typically weigh 2-4 kg, but can weigh up to 40 kg and reach more
than a metre in length.

They reproduce rapidly, with females being able to lay up to one
million eggs in a single spawning event."

- Ontario Ministry of Northern Development, Mines, Natural Resources
and Forestry

That compares to 20,000 eggs for a salmon and 120,000 for whitefish
and bass.
