Freshwater Fisheries

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 1.05%. 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.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 1.05%. ... 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible.

Freshwater fisheries are important economically in commercial, recreational, and subsistence fishing activities. Such fisheries depend on the health of fish populations, which in turn partly depends on the invertebrate food available to them.
