Control Aquatic Vegetation in Your Pond. Get Tips at Farm Science Review

September 7, 2010

LONDON, Ohio – Controlling aquatic vegetation, such as harmful algal blooms, can be the biggest challenge when it comes to managing a pond for fishing, swimming or other recreational use.


Come to Ohio State University's Farm Science Review and learn what a fish management specialist would do to manage his own private pond.

Bill Lynch, an Ohio State University Extension associate in aquatic ecosystem management, will present, "If It Were My Pond, I Would…." at the Gwynne Conservation Area Sept. 21 from 10:30 a.m. until 11:30 a.m. and Sept. 22 from 1:30 p.m. until 2:30 p.m. Farm Science Review will take place Sept. 21-23 at the Molly Caren Agricultural Center in London, Ohio.

Attendees can get to the Gwynne by catching the free shuttles at the west end of the exhibitor grounds.

"Excessive aquatic vegetation is what causes all of the headaches for pond owners," said Lynch. "It's the most challenging aspect of pond management because of all of the excess nutrients that end up in the water."

Lynch said that cattails, filamentous algae and harmful algal blooms are some of the more common aquatic surface vegetation found in ponds.

"I'll be educating folks on how I would deal with that aquatic vegetation, how much I'd tolerate and what I would not tolerate," said Lynch. "For example, I tell people that submerged plants, like pond weeds, are good for fish diversity. Bass and bluegill didn't evolve in a bathtub. "

In addition to fish management, Lynch will touch on other issues, such as Canada geese and muskrat management, for a more balanced aquatic system.

Lynch's presentation is just one of 25 educational sessions taking place at the Gwynne Conservation Area during Farm Science Review. For a complete schedule, log on to
