Arctic char Arctic char offers an alternative to farmed salmon that lacks many of salmon's environmental problems. A species native to the northern regions of Europe and North America, Arctic char is in the salmon family and possesses a similar texture and flavor. Most char in the marketplace is raised on land in tank systems where the water is recirculated, thereby reducing the risk of disease transfer, pollution and escapes. Fish farmers are now experimenting with similar land-based technologies to grow other species, even salmon.
