Freshwater Fish (Stock Footage)

Freshwater Fish (Stock Footage)

Filmed at Lake Bohinj, Slovenia. Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 0.05%. These environments differ from marine conditions in many ways, the most obvious being the difference in levels of salinity. To survive fresh water, the fish need a range of physiological adaptations.
