It normally inhabits slow-moving freshwater habitats, particularly lakes and lowland rivers. In Germany, the tench is called Schlei.

The fish is native to Europe, but has been introduced to the americas, Africa, Australia, and Asia (Alas et al. 2009). Tinca tinca are a significant food source in Europe and highly valued for fishing. There have been many attempts at cultivating and introducing tench into the wild.

Tench were originally cultivated in the us by the united states Bureau of Fisheries beginning around 1883 and were later stocked in different waters. This fish were brought into Washington D.C. in 1885 for cultivation, but in 1888 and 1889 the Potomac flooded in the farm ponds and many tench escaped and spread throughout the water systems in the eastern us. In 1922 tench were brought over from italy by mr. Graviati who created a farming pond in san mateo County, California.

Tinca tinca were additionally intentionally discharged into Lake Washington once they were placed on exhibit in point of entry for the Alaska-Yukon Exposition in 1909. Tinca tinca from the honest were transferred the University of Washington and place in an exceedingly massive pool.

Distribution and habitat

Tench are currently found throughout Europe, their native land, and has been introduced to North America, South America, Africa, Australia, and Asia (Alas et al. 2009). typically in shallow, densely vegetated lakes and backwaters. typically overwinters buried in mud. Spawns among dense vegetation in still water.

Naturally absent only in ireland, Scandinavia north of 6130’N, eastern adriatic basin and western and southern greece where it is now introduced. In Asia, native eastward to western Yenisei drainage south of 60N. Introduced to North and south africa, Tasmania, Australia, New zealand, India, North America, Chile and probably elsewhere. In Asia, native eastward to western Yenisei drainage south of 60° N. Introduced elsewhere.

Parasitic diseases are the most frequent diseases diagnosed in Tinca tinca. They are found mainly in tench from warmwater fish farming facilities and from ponds in spring after wintering.
