The Bismarck Tribune is reporting:
This was a good year for raising walleyes at the Garrison Dam National
Fish Hatchery — a record-setter in terms of the number of walleyes
stocked in North Dakota lakes.
Thanks to new pond liners at the
hatchery and some weather-related issues, more than 11 million walleyes
were stocked in state lakes this year, a record for the North Dakota
Game and Fish Department.
The U.S. Fish and Wildlife Service's
hatchery at the dam and the Game and Fish Department for years have
worked in harmony to grow multiple species for not only North Dakota
lakes, but for other states as well.
Rob Holm, hatchery manager,
said the biggest change that has resulted in increased production has
been the installation of new pond liners.
One wonders if these new liners are/were related in any way to the liners operators use on pads for waste pits.
Holm said in 2009, the last of the old clay-lined, sand-bottomed
rearing ponds at the hatchery were retro-fitted with 40-mil polyethylene
liners.
He said the new liners, at a cost of about $90,000
apiece, have increased the efficiency of how the hatchery is able to
raise not only walleyes, but other species of fish in a number of ways.
So, how successful was the effort this year?
This year's 9.7 million walleyes produced at the hatchery is third on the
list for all-time production.
Two years ago the record of 10 million
was set and last year that number was 9.9 million.
