Adult paddlefish are often caught during broodstock and are returned to the water immediately.
According to the Herald-Whig article “Officials at a federal fish hatchery in southwest Missouri are hoping that new water tanks will provide a better breeding environment for endangered pallid sturgeon. Endangered Species Act for Pallid Sturgeon, Factor E – Other Natural or Manmade Factors Affecting its Continued Existence, Factor D – Inadequacy of Existing Regulatory Mechanisms, Factor B – Overutilization for Commercial, Recreational, Scientific, or Educational Purposes, Factor A – Present or Threatened Destruction, Modification or Curtailment of it’s Habitat or Range, Recovery Effort Contracts and Documentation, Pallid Sturgeon Technical Lead position available, Upper Basin Pallid Sturgeon Workgroup Annual Meeting March 3-4, 2020, Final Pallid Sturgeon Basin-Wide Contaminants Assessment, 2020 Upper Missouri River Basin Pallid Sturgeon Working Group Annual Meeting Scheduled. The confluence of the Missouri River with the Yellowstone River – a very important area for Pallid Sturgeon recovery efforts. Depths used were 0.6 to 14.5 meters and averaged 3.30 meters, and they appeared to move deeper during the day (Bramblett 1996). afterLoad: function() {

And like a canary in a coal mine, the plight of the pallid sturgeon serves warning that the overall health of the ecosystem has suffered.” So, it is quite obvious that without this odd looking fish, the overall quality of the ecosystem will decline and that is why scientists are hoping for a beautiful recovery of these ugly animals. Therefore, to avoid jeopardizing the continued existence of the pallid sturgeon, while continuing operation and maintenance of the 9-foot channel, further net loss or … jQuery(".slider-wrapper-5f7722a173331").show();
It is an ancient species that has existed since the days of the dinosaurs. Sturgeon were found to have moved 54% of the time between relocations; they moved up to 21.4 kilometers per day and 9.5 kilometers per hour (Bramblett 1996). Their mouth is toothless and positioned under the snout for sucking small fishes and invertebrates from the river bottom. This behavior is thought to be one of the limiting factors affecting larval survival. }, // Triggers after a slide transition

Pallid Sturgeon are long-lived and are thought to spawn at several year intervals.
Water turbidity ranged from 12 to 6400 NTU (Turbidity Units) (Tews 1994). The Pallid Sturgeon is the larger of the two species of sturgeon found east of the Continental Divide. The Pallid Sturgeon has been declining during at least the past 50 years with only about 200 adults remaining in the upper Missouri River and limited natural reproduction.

What are these ugly creatures? They use all channel types, primarily straight reaches with islands (Bramblett 1996). For generations, the pallid sturgeon swam freely in rivers from Montana to New Orleans. Annual home ranges for Pallid Sturgeon in Montana ranged from 12.4 to 331.2 kilometers with a median of 52 kilometers; seasonal home ranges were smaller in fall and winter than in spring and summer (Bramblett 1996). Pallid Sturgeon (Scaphirhynchus albus) Pallid sturgeon are bottom dwelling, slow growing fish that feed primarily on small fish and immature aquatic insects.

After a long history of ancestral survival through environmental disruptions, mass extinctions and multiple glaciations of North America, this unique fish, the Pallid Sturgeon, is in murky water both literally and figuratively. Beginning in 1996, research efforts focused on Pallid Sturgeon recovery and preserving the Pallid Sturgeon genetic pool through stocking. Spring snow storm during broodstock collection. Pallid Sturgeon use large, turbid rivers over sand and gravel bottoms, usually in strong current; also impoundments of these rivers (FWP).

It has been suggested that larval Pallid Sturgeon may end up being deposited in downstream reservoirs and consequently never reach suitable rearing habitat.
