This small species of fish has been found near Taughannock Falls State Park. Though it may feed some on the invasive zebra mussel, it is not likely to have a significant impact on reducing that species. Instead, it will likely cause a reduction of native fish due to habitat competition and it’s appetite for fish eggs.

Hydrilla and Round Gobies in Cayuga Lake

Episode 54 of Walk in the Park TV is now showing! See it beginning tonight (Thursday, 9/5/13) at 9:00 on Ithaca, NY’s public access cable channel 13 (or 97.3) or right here online!

In our show today:
The aggressive invasive aquatic weed Hydrilla was discovered in Cayuga Inlet in Ithaca a couple of years ago by the Cayuga Lake Floating Classroom. A massive effort to control this plant has greatly reduced its numbers, but recently plants were found in nearby Fall Creek and in Cayuga Lake itself near Stewart Park, an alarming development as this plant could threaten to clog shallow waters throughout the Great Lakes basin. Also discovered in Cayuga Lake for the first time is the invasive exotic fish the round goby, seen near Taughannock Point at Taughannock Falls State Park.
Finally, we go back to Stewart Park for the 30th annual Labor Picnic on Labor Day, sponsored by the Mdistate Central Labor Council, AFL-CIO, and the Tompkins County Worker Center. Heros in the movement to get more employers to pay a living wage in the county were honored. The Evil City String Band put on a little concert.
