Large tench may be found in gravel pits or deep, slow-moving waters with a clayey or silty bottom and lots of aquatic vegetation. They take a variety of baits but are "nibblers" and can be difficult to hook.
The tench are getting larger and soon the big girls will arrive. At 8lbs 10oz there is still some room to grow. Have a look at my blog http://www.kpanglingguide.com/blog/
