Characteristics & Appearance
The White Sturgeon is one of the biggest fish species in the world and the largest freshwater fish in North America. This species is a true giant of the waterways, reaching lengths of up to 20 feet (6.10 cm) and weights of over 1,500 pounds. Its body is covered in sizable bony plates that protect it from predators. For those familiar with the species, the fish’s distinctive and ancient appearance created by these plates makes it easy to identify.
Depending on its habitat and age, the White Sturgeon’s color can range from a dark grey to a brownish-green. The color of their underside is typically lighter, ranging from cream to pale yellow. The White Sturgeon can locate food in the murky river bottoms where it frequently lives thanks to its long, flat snout and four underneath sensitive barbels. It has a large mouth on the underside of its snout, but the jaws lack teeth; instead, it uses a specialized cartilage pad to crush its prey.
Did you know that one of North America’s largest freshwater fish species is the white sturgeon? In terms of size, it is only surpassed by the Beluga Sturgeon, a close relative of the White Sturgeon. The largest White Sturgeon ever measured weighed a whopping 1,500 pounds and was more than 20 feet long! These enormous fish are impressive not only for their size but also for how long they can live—up to a century. It is understandable why White Sturgeon are a highly sought-after game fish species among anglers given their distinctive appearance, adaptability, and longevity.
White sturgeon is a freshwater fish, primarily found in the Columbia River Basin and its tributaries in the Pacific Northwest of North America. Additionally, it can be discovered in Canadian, Montanan, and Californian rivers and estuaries. The White Sturgeon can find a plentiful food supply in its habitat, consisting of deep, slow-moving rivers with soft bottoms and sandbars. It is a fish that lives on the bottom and prefers to spend most of its time near the riverbed, where it can use its barbels to find food in the murky water.
A migratory species, the white sturgeon travels between freshwater and saltwater habitats to breed. Adult fish migrate upriver in the spring to spawn in gravel beds and shallow riffles. The juvenile fish stay in the shallower areas of the river where they can find food and shelter after spawning while the adults return to the deeper parts of the river.
Food & Diet
The White Sturgeon consumes various prey, including other fish, crustaceans, and mollusks. It is an opportunistic feeder. It has a different diet depending on its size, habitat, and age. While adult White Sturgeon eat larger prey like salmon, lamprey, and clams. The juvenile White Sturgeon eat small aquatic insects, crustaceans, and worms.
The mouth of the White Sturgeon is perfectly suited to its feeding preferences. It has a sizable, fleshy pad that it uses to break up clam shells and other hard mollusk shells. It also uses the barbels on its snout to hunt for prey in the muddy river bottoms where it frequently lives.
Depending on the season, the White Sturgeon’s feeding habits change. White sturgeons are more active and feed more frequently in the spring and summer when the water temperature is warmer. They tend to eat less in the winter because their metabolism slows down and the water is colder.
Threats & Predators
A white sturgeon can live for over 100 years, making it a long-lived species. It does, however, face a number of dangers and predators that could affect its population.
The destruction and fragmentation of habitat are two major threats to the White Sturgeon. The flow and quality of freshwater habitats can be changed by dams, water diversions, and other human activities, making it more challenging for White Sturgeon to locate suitable spawning and feeding grounds.
In addition, a variety of other animals, such as sea lions, harbor seals, and raptors, prey on white sturgeon. White Sturgeon are more susceptible to predation by these animals when they migrate from freshwater to saltwater environments to breed.
