The Kootenai River white sturgeon population is threatened by dam operations, flood control operations, water quality degradation and loss of habitat. It's also covered in rough, scale-less skin, similar to a shark. Yep. Trout stocking in lakes and ponds continues for now. Declines in water quality and altered flows have also negatively affected white sturgeon The white sturgeon is currently listed as "S1" in MT due to extremely limited and/or rapidly declining population numbers, range and/or habitat, making it highly vulnerable to global extinction or extirpation in the state.The Kootenai River population of white sturgeon (Kootenai sturgeon) has been declining during at least the past 50 years with only about 500 wild adults remaining. They have also been frequently spotted opportunistically foraging and transiting in the St. George, Medomak, Damariscotta, Sheepscot, Saco, Deerfield, East, and Susquehanna rivers. Cox was describing a species known today as the white sturgeon, the largest of about eight species of sturgeon that live throughout the rivers, lakes, and coastal waters of North America. The goal of the White Sturgeon Management Plan (WSMP) is to increase the white sturgeon ( Acipenser transmontanus) population in the Wells Reservoir to a level that can be supported by the available habitat and characterized by a diverse age structure consisting of multiple cohorts (juvenile and adult). Within their ecosystem, they spend most of their time foraging near the bottom. Farm-Raised California White Sturgeon. Although they were once a more common part of our native wildlife, nowadays Pennsylvania Sturgeons are rare.

The model was developed as a tool to aid understanding of the physical factors affecting quality and quantity of spawning and rearing habitat used by the endangered white sturgeon (Acipenser … White sturgeon behavior and facts. The species’ most distinguishing features include a mainly cartilaginous skeleton, long scaleless body covered with rows of large bony plates (called scutes) on the back and sides, shark-like (heterocercal) tail, and four barbels between the mouth and an elongated snout. Figure 1. In some parts of the world, Sturgeons are commercially valuable for their meat and for their eggs, which are used for caviar. endangered because the species has declined considerably over the last century and will likely continue to decline owing to localized habitat degradation and recruitment failure Juvenile… Features: There's no mistaking a sturgeon. Technique: Sturgeon are bottom feeders and have four barbels near their snouts. The Kootenai River’s endangered white sturgeon benefit from habitat protection and restoration at Wild River. Some species live in freshwater habitats. Along with overfishing, habitat destruction — including dams that close off spawning grounds — and pollution contributed to the decrease in white sturgeon populations. U.S.FWS Species profile about species listing status, federal register publications, recovery, critical habitat, conservation planning, petitions, and life history U.S. Although they are a bony fish (Class Osteichthyes), rather than a cartilaginous fish like sharks (Class Chondrichthyes), sturgeon actually have very little true bone. There are 27 species of sturgeon worldwide, two of which, White (Acipenser transmontanus) and Green (A. medirostris) – are native to California.
