Freshwater Fish of the Pacific Northwest
There are many lakes and rivers along the BC coast and they all have fish. Some coastal rivers have steelhead runs that contain fish that can weigh as much as 20 or more kilos. The cowichan river on Vancouver Island has brown trout that can reach up to 7 kilos.
Most of the rivers and lakes have fish more in the range of 30 to 40 cm in length. So grab your rod, put on your boots and try your luck, the fresh air will do you good.
Most good fishing areas have campsites that are available, some are full campgrounds with fire pits, tables and boat launches, others can be very rustic. But the camping is fun at any of them.
British Columbia contains a diverse and varied fish community. 10,000 years ago, the province was almost completely covered by a layer of ice. As the glaciers retreated, fish that survived through the big freeze were able to move into new territories. Some of these early colonizers became isolated from other populations by barriers such as waterfalls. This allowed them to become almost separate species.
There are many types of fish here, some were a saltwater fish that adapted to living in freshwater, arctic grayling, steelhead and rainbow trout are all freshwater fish that originally lived in the sea.
Why do some fish normally live in freshwater and others live in seawater, the reason is that one or the other environment provides them with opportunities that have traditionally contributed to their survival. An obvious difference between the two habitats is salt concentration. Freshwater fish maintain the physiological mechanisms that permit them to concentrate salts within their bodies in a salt-deficient environment, saltwater fish, on the other hand, excrete excess salts in their environment. Fish that live in both environments retain both mechanisms.
