Esti-mating Ns, Nb, larval dispersal, and inferred genetic connectivity between locations provides managers with population demographic parameters to assess habitat remediation projects. However, all the news is not grim. 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. Lake sturgeon can grow to weights of up to 200 pounds and lengths of seven feet, with females being longer and heavier than males. Lake Sturgeon have inhabited the Great Lakes for 10,000 years.

They are most often found over firm sand, gravel, or rubble bottoms. In addition to commercial fishing, the remaining sturgeon population faced a growing number of threats. Research needs identified by this strategy included the identification of historic and current spawning habitat, and information on seasonal movements and habitat use by lake sturgeon … Preferred HabitatPallid Sturgeon are well adapted for life on the bottom of a fast flowing, turbid river. Lake Sturgeon’s appearance on the ‘threatened’ species list is not recent and is attributed to overharvesting, habitat destruction, pollution, dam construction and their unusual biology including late maturity and breeding habits.
