A fish of ponds and slow rivers.

Catalogue names : Tench. Forms and names may vary between habitats.

Editorial review : · This species guide is not permission to fish. Read the precautions below and check the current rules for your location before targeting a species. Some species or populations are protected.

Geographical distribution

Considered native across much of Europe and east to the western Yenisei drainage in Asia. Some European margins, including Ireland, were reached through introductions. This broad range does not imply occupancy of all European waters.

  • Native range : Much of Europe and western Yenisei drainage

Distribution sources

Identification

Tinca tinca is recognisable by its olive colouring, small scales, rounded fins and small barbels at the corners of its mouth. The eye is often orange. Carp have a different body shape and barbels; do not rely solely on dark colouring.

Habitat

Shallow, densely vegetated water.

Diet

Larvae, crustaceans and molluscs.

Behaviour

Tench use the bottom to search for food, particularly invertebrates. They are often inconspicuous. Bubbles are not enough to identify them: mud, other fish and gases from the sediment can also produce bubbles. Observe before interpreting every sign as an imminent bite.

Fishing context and precautions

  1. To start near weed beds, choose float fishing as your main method. Pick an opening with room to play a fish out and plumb the depth without disturbing the plants.
  2. Prepare a float, adjustable shotting and a single hook. Position the bait near the bottom without laying the shot in the mud.
  3. Present the bait in the opening, then watch the float actively. Check the bait after a bite and adjust the depth slightly if mud buries it.
  4. Guide the fish towards open water and the landing net. A feeder remains another option in a more distant, clear area; float settings cannot be transferred directly to that method.

A distinctive feature

Its very small scales are covered by a thick layer of mucus.
