Freshwater is a vital and scarce resource on our planet with only 3% of the water on Earth being freshwater rivers and lakes, the rest being oceans. Freshwater rivers and lakes are formed when hollows are made in the Earth, such as when land collapses after a magma flow allowing for rainwater or melted snow to flow through and accumulate in the empty space. However, even though freshwater biomes are not expansive, they are still home to over 100,000 different species of plants and animals. Many amphibian species, such as turtles, frogs, and alligators, live in freshwater biomes. Mammals, such as otters and beavers, live in freshwater biomes too, with many more mammals stopping by a river or lake for a drink.

White Bass

The White Bass (Morone chrysops) is also called the sand bass, white bass, and silver bass. It is a freshwater fish of the family Moronidae that is primarily found in the Midwest United States. They spot a deep and compressed lateral body with silver-white to pale green color.

The belly of the White Bass is white and back dark. They also have continuous lines on their sides with two dorsal fins and rough scales and prefer large reservoirs and lakes. The White Bass spawn during daylight and near the surface with each female’s eggs fertilized by many males. The White Bass is social, preferring to breed and hunt in large schools.

White Basss have a total length between 10”-18” (25-46 cm), body height of 2.5”-5.5” (6.4-14 cm), and an overall weight in the range of 2-5 lb (.9-2.3 kg). The typical lifespan of the White Bass is 4-9 years.

Chum Salmon

The Chum Salmon (Oncorhynchus keta) are anadromous fish that are members of the family Salmonidae and number two after the Chinook salmon in size. The animal’s body color transforms as it enters either fresh or ocean water. They are also called dog salmon or keta salmon and spend very little time in freshwater, unlike the Chinook and Coho.

Chum Salmon inhabit the waters of the North Pacific and Arctic oceans having late spawning runs which make them less popular in sportfishing. The animal spots a deeper body with males at spawning time being more vivid than females, have elongated snouts, white tip on their lower fins, and large canine teeth.

Chum Salmon have a total length between 24”-40” (61-102 cm), body height of 6”-10” (15.2-25.4 cm), and an overall weight in the range of 8-22 lb (3.6-10 kg). The typical lifespan of the Chum Salmon is 3-7 years.
