Tench (Tinca tinca) Fish Description

The Tench is a popular freshwater gamefish that was introduced in the US during the 1870s from Germany specifically for game fishing. They have small, coarse, scales and are yellow-olive in hue. They have stocky body and their eyes are small. Their mouths are narrow and they have barbels in their lower jaws (like some carps). They use their barbels to search for ground-dwelling prey such as snails, and mosquito larvae, and other insects. Tench also eat plant matter such as algae.

They are hardy fish that can survive waters that are low in oxygen (that sometimes something a carp cannot even survive). They prefer warm still-waters of lakes, ponds, slow-moving rivers, and estuaries. Their habit is mostly surrounded by clay, muddy, with abundant vegetation. 

 

Interesting Facts About the Tench

The best time to fish some tench is from May to June where they spawn and where the waters are warm. They will aggregate to warm shallow waters where they will lay their eggs on aquatic plants. They tend to breed at temperatures of 68°-88°F. They also breed at temperatures such as 50°-60.8°F but they tend to mature and breed slower with these temperatures.
