Tench is our most common carp-type fish with incidence throughout the whole territory of the Czech Republic. 
The quality of tench in the Bohemian-Moravian Uplands is especially good. 
Abroad, tench is appreciated 2.5 times higher than carp. 
It grows slowly. In average, it reaches a weight of 0.5 to 1 kg, rarely 2 kg, and up to 7 kg as a maximum. 

We catch it all the year round in the lawful measure of 20 cm. We use finer instruments.
The best way of catching is the heavy, semi-heavy and floating method.
