Sturgeon

The lake sturgeon is the largest and longest lived of any of Canada’s freshwater species. An adult sturgeon can reach a length of 2.5 metres, weigh more than 150 kilograms and live more than 100 years.

 

The lake sturgeon had both cultural and subsistence importance to First Nations peoples. All parts of the fish were used: the meat was used for food; the skin was used as a container to store oil; and the pointed bones along the back were used as arrow heads. Today, lake sturgeon continue to be revered both culturally and as a valued food source to First Nations peoples.lake sturgeon

We are fortuitous to have relatively healthy lake sturgeon populations in sections of the Ottawa River, however, these populations are under constant threat from development, exploitation, and more recently poaching due to the collapse of sturgeon stocks in eastern Europe for the caviar trade.
