The top and side bony plates (called scutes) are the same color as the dull grey body and the peritoneum (body cavity lining) is black. Early commercial fishermen scorned sturgeon as nuisance fish that destroyed their gill nets. Lake sturgeons can grow huge. Other management efforts focus on tracking sturgeon migration and identifying the location of remaining spawning grounds. The lake sturgeon was once an important component of the fish fauna of the Great Lakes watershed, but is currently endangered in much of its range due to overfishing and habitat degradation. In New York, lake sturgeon have been collected in St. Lawrence River, Niagara River, Oswegatchie River, Grasse River, Lake Ontario, Lake Erie, Lake Champlain, Cayuga Lake, and in the Seneca and Cayuga canals.

Habitat Requirements Lake Sturgeon requires a variety of habitats to complete its lifecycle, and the species has evolved to exploit typical upstream to downstream hydraulic and substrate gradients. When European settlers arrived in the region, sturgeon were so numerous during the spring spawning run that they were reportedly capable of capsizing fishing boats. The lake sturgeon is a cartilaginous fish with large bony plates, a heterocercal (shark-like) tail, and a pointed snout with barbells used to locate food (Harkness and Dymond 1961). Lake sturgeon do not adapt readily to change, whether from exploitation or from habitat alterations. Some species live in freshwater habitats. The Lake Sturgeon Acipenser fulvescens is a fish species that was once dispersed widely throughout the Mississippi River drainage but was largely extirpated from the southern portions of its range by overfishing and habitat degradation. The New York State Department of Environmental Conservation (DEC) is collecting biotic and abiotic data on lake sturgeon populations. “The rehabilitation of lake sturgeon is a reflection of the Tribe’s present-day progression as a community and a tribal government,” says Gun Lake Tribal spokesman, James Nye.

Females live 80-150 years. Within their ecosystem, they spend most of their time foraging near the bottom. To locate these delectable creatures, the lake sturgeon must linger at the bottom of lakes with extensive areas of shallow water (less than 30 feet) and in deep river pools, foraging where food is abundant. Some species live in freshwater habitats. In 1880, more than 4 million pounds of sturgeon were processed in Michigan, taken from Lake Huron and Lake St. Clair. Its abundance has not recovered from 19th century declines. In addition to the ecological degradation associated with an increase in sediment input to streams, these sites are of particular interest in that this stretch of the Black River is known spawning habitat of the state-threatened lake sturgeon. Do some homework beforehand to find the best sturgeon waters in the area you plan to fish.

Pallid sturgeon also have been captured in downstream reaches of several major tributaries of the Missouri River, such as the Platte Big Sioux, James, and Niobrara Rivers. Criteria were developed to assess rivers and lakes in Michigan for populations and habitat. These results delighted team members because it meant that a state endangered fish species – lake sturgeon – found the new habitat structures and deemed them suitable for spawning. The lake sturgeon is a species that has remained virtually unchanged since swimming alongside the dinosaurs. Life History and Habitat . In some areas of the state, volunteers help monitor spring spawning runs to protect sturgeon from being taken illegally. They usually forage along the bottom of water bodies, or benthic regions. Mature adults average between 3-5 feet in length and 10-80 pounds in weight, but can occasionally grow as large as 7+ feet and 300+ pounds. potential habitat available to lake sturgeon. The Lake Sturgeon is considered endangered (571 IAC 77.2(1) (2015)) as it has steadily decreased in abundance since 1900.
