the Vendace  

Coregonus vandesius is a freshwater fish found in the United Kingdom. Its common name is vendace, which otherwise refers to Coregonus albula. It is one of three species of whitefish in the UK. The species inhabits deep, cold lakes, and uses planktonic crustaceans, such as copepods, as its primary food source.
The fish does not migrate and has a lifespan of about six years. The species is now Britain's rarest fish.

In 2011, 25,000 newly hatched fish were transported by llamas 500m up mountain paths to Sprinkling Tarn, near Seathwaite Fell in the Lake District. This project aims to establish a vendace "refuge".

The vendace has only ever been known as a native species at four sites, Bassenthwaite Lake and Derwent Water in the English Lake District, and the Castle Loch and Mill Loch in Lochmaben, Scotland. The species is thought to have died out at all of these sites except Derwent Water. The Castle Loch population disappeared in the early part of the 20th Century, and the Mill Loch population disappeared in the 1990s. The fish has not been recorded at Bassenthwaite Lake since 2001. The declining populations of the fish are thought to be due to introduced species that utilise the native vendace as a food source, and also due to pollution. However in 1997 and 1999 a number of fish from Bassenthwaite were transferred to Loch Skeen, near Moffat in south west Scotland. There are now 10 times as many vendace per hectare in the scottish loch compared to Derwent Water. Conservationists hope to reintroduce the fish to Bassenthwaite Lake once the habitat is restored.
