Sturgeon are the largest of the freshwater fish. The beluga sturgeon in Russia is the largest freshwater fish in the world. The white sturgeon is the largest freshwater fish in North America. White sturgeon have been reported to reach lengths of 15-20 feet and weights of nearly one ton. The second largest freshwater fish in North America is the alligator gar.

Are sturgeon and catfish related?
No. Although sturgeon and catfish can be found in the same habitats and they both have barbels (whiskerlike growths extending from the jaw), they are not closely related. Sturgeon are much more primitive than catfish. There are some catfish sold for aquariums that look somewhat like sturgeon, and some fish have common names that are misleading (i.e. sturgeon chub) but these fish are not related to...
Where can I find fish consumption advisories for my state?
Most states have set fish (and wildlife) consumption advisories and recommended consumption levels. The state agency responsible for these limits varies. Examples of consumption advisory information can be found at the Environmental Protection Agency's Fish and Shellfish Advisories and Safe Eating Guidelines website.
Are lamprey and hagfish related?
Yes. Lamprey and hagfish are both jawless fishes. They are the only living members of the taxonomical class Agnatha (Greek for “no jaws”).Learn more: Sea Lamprey Species Profile

Developing fluvial fish species distribution models across the conterminous United States—A framework for management and conservation
This report explains the steps and specific methods used to predict fluvial fish occurrences in their native ranges for the conterminous United States. In this study, boosted regression tree models predict distributions of 271 ecologically important fluvial fish species using relations between fish presence/absence and 22 natural and anthropogenic landscape variables. Models developed for the fresAuthorsHao Yu, Arthur R. Cooper, Jared Ross, Alexa McKerrow, Daniel J. Wieferich, Dana M. InfanteThe Missouri River Scaphirhynchus albus (pallid sturgeon) effects analysis
The Missouri River Pallid Sturgeon Effects Analysis (EA) was designed to assess how Missouri River management has affected—and may affect—the endangered Scaphirhynchus albus (pallid sturgeon) population. The EA emerged from the recognition that the direction and focus of the Missouri River Recovery Program would benefit from an updated, thorough evaluation of what is known, what is not known, andAuthorsRobert B. JacobsonModeling Climate Change and Sturgeon Populations in the Missouri River
The U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC), in collaboration with researchers from the University of Missouri and Iowa State University, is conducting research to address effects of climate change on sturgeon populations (Scaphirhynchus spp.) in the Missouri River. The CERC is conducting laboratory, field, and modeling research to identify causative factorsAuthorsMark L. WildhaberThe pallid sturgeon: Scientific investigations help understand recovery needs
Understanding of the pallid sturgeon (Scaphirhynchus albus) has increased significantly since the species was listed as endangered over two decades ago. Since 2005, scientists at the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) have been engaged in an interdisciplinary research program in cooperation with the U.S. Army Corps of Engineers Missouri River Recovery ProgrAuthorsAaron J.
