Tench

Tinca tinca

About

Tench are medium-sized, heavy, deep-bodied fish. They can be found in soft-bottomed lakes and in slow-flowing rivers with plenty of vegetation. They are quite shy fish, hiding amongst dense weed. Tench feed on invertebrates including pond snails and small pea mussels. Spawning in summer, males chase females, fertilising the eggs as soon as she has laid them in shallow beds of algae or vegetation.

How to identify

Dark greeny-bronze in colour with blackish, rounded fins and sometimes with a golden-orange throat and belly.

Where to find it

Found throughout the lowlands, widespread in England but rarer in Wales and Scotland.
