How To Identify Sturgeon

Identifying lake sturgeon (Acipenser fulvescens) involves understanding their distinct characteristics. These ancient, large freshwater fish native to North America are among the largest in the region, reaching lengths of up to 7 feet or more and weighing several hundred pounds. 

They possess an elongated body with a pointed snout and tough, bony plates called scutes covering their rough, armored exterior. Lake sturgeon typically display a dark gray to olive-green coloration on their backs, fading to lighter shades on their sides and belly. Their four barbels near the mouth aid in locating food along the bottom of rivers and lakes. Additionally, their heterocercal tail, with the upper lobe longer than the lower lobe, provides stability and propulsion while swimming. 

Lake sturgeon also feature a single dorsal fin toward the rear of the body, paired pectoral, pelvic, and anal fins. They thrive in large, deep freshwater lakes and rivers with clean, well-oxygenated water, often preferring sandy or rocky bottoms for spawning and foraging. As bottom feeders, they primarily consume small invertebrates, insect larvae, mollusks, and small fish. 

Lake sturgeon are known to migrate long distances to specific riverine habitats for spawning. Despite their resemblance to other sturgeon species and their relatively rare sightings, enthusiasts and researchers can accurately identify lake sturgeon by considering their size, body shape, distinctive features, and habitat preferences in their natural environment.

Habitat

Lake sturgeon typically inhabit large, deep freshwater bodies such as lakes and rivers across North America. These ancient fish are known for their preference for cool, clean water with adequate oxygen levels. Lake sturgeon are often found in areas with rocky or sandy substrates, although they can adapt to a variety of bottom types. 

They are commonly associated with areas of moderate to swift currents, especially during their spawning migrations. Lake sturgeon are known to inhabit both shallow and deep waters, depending on the season and availability of food. 

During the warmer months, they may move to deeper, cooler waters to escape warmer surface temperatures, while in the spring, they often migrate to shallow areas with suitable spawning habitats. Lake sturgeon are also sensitive to changes in water quality and habitat degradation, making conservation efforts crucial for maintaining healthy populations. Protection of their spawning grounds, restoration of river habitats, and sustainable fishing practices are essential for the long-term survival of lake sturgeon populations.

Natural Food Source

Sturgeon, including lake sturgeon, primarily feed on a variety of bottom-dwelling organisms found in their freshwater habitats. Their natural food sources consist mainly of small invertebrates such as insect larvae, crustaceans, and mollusks. Lake sturgeon are particularly adept at using their sensitive barbels to detect and locate prey in the substrate or sediment at the bottom of rivers and lakes. They often feed by suction, using their protractile mouth to vacuum up small organisms from the substrate.

In addition to invertebrates, sturgeon also consume small fish species such as minnows, shad, and other small baitfish when available. However, fish make up a smaller portion of their overall diet compared to invertebrates.

Sturgeons are opportunistic feeders, and their diet can vary depending on factors such as habitat, season, and prey availability. While they primarily forage near the bottom of water bodies, they may also feed in mid-water or near the surface, especially during periods of heightened activity or migration.

Understanding the natural food sources of sturgeon is essential for conservation efforts and managing their habitats effectively. Preserving the quality and availability of their food supply is crucial for maintaining healthy populations of sturgeon in their native freshwater environments.

How To Catch

In New York, catching sturgeon is strictly prohibited due to conservation efforts aimed at protecting these endangered species. The American Fisheries Society has categorized lake sturgeon as threatened across all states where they are found. 

The decline in lake sturgeon populations has been attributed to various factors, including overexploitation driven by high demand for their eggs (caviar) and smoked flesh, habitat degradation caused by the construction of dams, and pollution resulting from urban and rural development.

The New York State Department of Environmental Conservation (DEC) is actively involved in collecting data on lake sturgeon populations and implementing conservation measures. To restore populations, DEC employs artificial propagation techniques in selected tributaries of Lake Ontario and the St. Lawrence River, such as the Oswegatchie River, Black Lake, the St. Regis River, Oneida Lake, and Cayuga Lake.

It’s important for anglers and the public to recognize that all sturgeon species found in New York, including lake sturgeon, are protected. It is illegal to target, catch, or possess sturgeon in New York waters to ensure their conservation and long-term survival.

Spawning Habits of Sturgeon

Lake sturgeon exhibits fascinating spawning habits that are vital to their lifecycle and population dynamics. Spawning typically occurs in the spring, from May to June, as adult sturgeon gather in groups in deep holes near the spawning site. Prior to spawning, sturgeon engage in “staging” displays, rolling near the bottom and leaping out of the water with a resounding splash. 

The actual spawning takes place in areas with clean, large rubble, such as along windswept rocky shores of islands and in rapids in streams. During spawning, the eggs are scattered by currents and adhere to rocks and logs. Young sturgeon hatch out within 5-8 days and experience rapid growth, reaching up to 7.5 inches by the end of the first growing season. Remarkably, a mature female lake sturgeon may lay anywhere from 100,000 to 800,000 eggs during a single spawning season. 

Lake sturgeon are renowned for their longevity and slow maturation process. Female sturgeon do not reach sexual maturity until 14-23 years old and can live up to 80 years, while male sturgeon reach maturity at 8-19 years old and may live up to 55 years. Notably, in 1953, a 154-year-old lake sturgeon weighing 208.5 pounds was caught in Lake of the Woods, Canada, underscoring their remarkable lifespan. 

Lake sturgeon are bottom feeders, utilizing their barbels to locate food and then suctioning it into their mouths. Their diet includes leeches, snails, clams, other invertebrates, small fish, and even algae, highlighting their crucial role in maintaining ecosystem balance and health. Understanding the spawning habits and lifecycle of lake sturgeon is vital for conservation efforts and ensuring the long-term viability of this remarkable species.

Regulations

In New York, regulations strictly prohibit the capture of sturgeon, as these species are under protection due to their endangered status. Recognized by the American Fisheries Society as threatened across states where they inhabit.

To address the decline in sturgeon populations, the New York State Department of Environmental Conservation (DEC) actively monitors and collects data on these species. DEC has initiated artificial propagation programs in selected tributaries of Lake Ontario and the St. Lawrence River, including the Oswegatchie River, Black Lake, the St. Regis River, Oneida Lake, and Cayuga Lake, to restore sturgeon populations.

It is essential for anglers and the public to adhere to regulations prohibiting the targeting, capture, or possession of sturgeon in New York waters. These measures are crucial for safeguarding sturgeon populations and ensuring their long-term survival in New York’s aquatic ecosystems.
