5203 |a"The Tench (Tinca tinca) is a large minnow species that has been introduced to Canada and is established in several locations in British Columbia and Quebec. Tench has been identified by Fisheries and Oceans Canada's Centre of Expertise for Aquatic Risk Assessment as being a species that may require a detailed level risk assessment. This biological synopsis, a required component of the risk assessment, includes a description, distribution, biology, natural history, human use, impacts and management practices of the Tench. The Tench, which is native to Europe, has been introduced into Africa, Asia, Australia, New Zealand and North and South America largely for aquaculture and sport fishing. Although it is established in many countries, its impact is either unknown or considered to be minor. However, when Tench occurs in high densities a cascade effect in the food chain may occur. Tench feeding on browsing gastropods causes an increase in periphyton growth on macrophyte surfaces. This increase reduces light penetration and nutrient supply to macrophytes, resulting in their decline. As Tench survives in degraded environments, it is unclear whether it impacts the water quality or simply inhabits a niche that other species cannot occupy"--Abstract, page iv.
