With winter fast approaching,
we are gearing up for our annual Fisheree on Long Lake. This event is always a
great time to come back to the lake for those who only spend
the summers here and get caught up on the changing seasons.
This year will be extra special! As always, the club will
be erecting a tent out on the lake (weather permitting).
Many of you know that the access to the lake from Mr. Ed’s
Campground has been closed. Well no more. This past
weekend, I visited the new Timber Lake Lodge bar which has
opened at Ed’s and was informed that the launch will be
opened. This means that our tent will be placed just out
from the launch with easy access from highway 67. YAH!!
For the past several years, those wishing to come to the
tent have had to get on the lake from either Benson’s
Hide-a-Way or the State Park. Having access from 67 will
most certainly increase the number of people joining us out
on the ice.
Club members will be out on
the ice early Sunday morning serving coffee, hot chocolate,
doughnuts and getting the tent warmed up. As the day
progresses, we will serve chili, burgers, brats and of
course refreshments. The fish registration will start
measuring fish at 6 a.m. and throughout the day. This is a
great attraction. We are hoping to have some big fish to
view in our live tank, as well as fish hanging from the
board. As always our plan B in the event that the ice is to
thin for the tent will be to move the food and beverages to
the Dundee Sportsmans Club, but the fish registration will
be on the lake even if Charlie has to sit in a boat. For
right now, we are keeping a positive attitude.
For those of you, who would
like to get more involved in this activity, please give me a
call. I can be reached most evenings at home 920-533-4770.
We are always looking for help raising the tent on Saturday,
February 2nd. We get started about 9 a.m. and
are usually done by noon. Take down is another time we need
your help. This happens on Monday morning February 4th.
See you on the ice! |

Biological control (or
biocontrol) is one possible tool that deserves further
consideration. Biocontrol offers several potential
advantages over conventional methods, including reduced
cost, long-term effectiveness, and little or no negative
impacts on other aspects of aquatic systems. Several aquatic
insects have been associated with declines of Eurasian
Watermilfoil (see
Sheldon and Creed 1995), providing the impetus for
research into biocontrol of Eurasian Watermilfoil. Current
efforts in Minnesota and elsewhere are focused on the native
milfoil weevil, Euhrychiopsis lecontei, which has
been associated with natural declines of Eurasian
Watermilfoil (e.g.,
Creed 1998) and has shown potential in controlled
experiments in the field (e.g.,
Creed and Sheldon 1995,
Sheldon and Creed 1995), and experimental tanks (Newman
et al. 1996).
The milfoil weevil is native
to North America and is a specialist herbivore of
watermilfoils. Once exposed to the exotic Eurasian
Watermilfoil, the weevil prefers Eursasian over its native
host northern watermilfoil (M. sibiricum) (Solarz
and Newman 1996). Adult weevils live submersed and lay
eggs on milfoil meristems. The larvae eat the meristem and
bore down through the stem, consuming the cortex, and then
pupate (metamorphose) lower on the stem (Sheldon
and O'Bryan 1996a). Develop from egg to adult occurs in
18-30 days at summer temperatures (Newman
et al. 1997,
Mazzei et al. 1999). The consumption of meristem and
stem mining by larvae are the two main effects of weevils on
the plant and this damage can suppress plant growth (Creed
and Sheldon 1993a,
1995), reduce root biomass and carbohydrate stores (Newman
et al. 1996) and cause the plant to sink from the water
column (Creed
et al. 1992). Although the weevil has been quite
effective at some sites, it has not been effective at other
sites. Currently, we cannot predict when, where and how the
weevils will or will not be effective. The aim of our work
is to improve our understanding so we can predict effects
and appropriate circumstances for use of biocontrol. |
