Vendace (Coregonus albula) are thought to have been present in the lake for over 11,000 years, becoming trapped there after glaciers retreated.

The species is also thought to be one of the first to have arrived and settled in UK, but has only ever been documented in two lakes in England; Bassenthwaite Lake and Derwent Water.

Scientist Dr Ian Winfield from the Centre for Ecology & Hydrology, Lancaster, who captured the video of the fish, explained that work on the species and monitoring/sampling has been taking place since the 1990's using survey gill nets and hydroacoustics.

The latest sampling (November 2016) estimates there to be around 5000 Vendace adults present in the lake.

In other news, Geraldton Fishermen’s Co-operative is to build a 80-tonne live lobster holding facility which will allow Australia to increase its exports to China.

The co-operative is Western Australia’s biggest rock lobster processor and has secured a $3.5 million loan through the Government’s Co-operative Loan Scheme to build the facility at Welshpool.

When completed, it will be Australia’s biggest rock lobster holding tank facility, enabling air freight of fresh rock lobster into China to reduce the time from ‘catch to plate’.
