At certain times of the year sturgeon travel very little, while at other times they can migrate over 100 kms. Many fish will spend the majority of their lives in freshwater, while others spend more time in saltwater, only entering freshwater to spawn. There have been sightings of Sturgeon jumping off the west coast of Vancouver Island and there have been confirmed fish that have been originally tagged from the Columbia River in the USA with pit tags and recaptured in the Fraser River. Some of the fish that have been caught in the river have had barnacles on them also, which means that they definitely came from the ocean. Also, it is thought that the fish that do come from the ocean have extremely sharp and large scutes which are the boney platelets along the back, sides and leading edges of the belly. The Sturgeon that live in the river tend to have duller scutes from swimming around gravel and river bottom. There is still a great deal to learn about these great fish and every time we catch one, we have the opportunity to learn something new.
