Grass carp, a type of large fish that eats unwanted overgrowth from ponds, have survived their first year as guests of the Wilton Conservation Commission at Kent Pond and are growing into their job.
That is, to clean up reeds from the pond when they are large enough next summer, said Mike Conklin, director of environmental affairs.
“I’ve seen no dead fish,” Conklin said June 28.
Wilton owns most of the pond, which has become overgrown with reeds. The commission stocked the fish last summer with a permit from the state Department of Energy and Environmental Protection.
Like Horseshoe Pond neighbors before them, neighbors of Kent Pond had their fill of scum growing on the water and the overgrown condition of the banks. They formed a committee to clean it up and get the town involved.
The group calls itself Friends of Kent Pond.
It’s a significant pond because it feeds into Rock Lake, a local reservoir.
A combination of biological and manual control will be used to manage the invasive plants in Kent Pond. The fish were 10 to 12 inches long when they were stocked and will grow to be 24 to 36 inches in maturity.
Grass carp are productive eaters for five to six years before they slow down and restocking is necessary.
