  • Shovelnose Sturgeon Scaphirhynchus Platorynchus
    shovelnose sturgeon Scaphirhynchus platorynchus Kingdom: Animalia FEATURES Phylum: Chordata A shovelnose sturgeon's average weight is one and Class: Actinopterygii one-half to two pounds. The maximum length is Order: Acipenseriformes about 30 inches, and the maximum weight is about five pounds. Four fringed barbels (whiskerlike Family: Acipenseridae projections) are present on the chin near the ILLINOIS STATUS sucking-type mouth. Bony plates along the back, a forked tail and a flat head in the shape of a shovel common, native are all characteristic traits. The body is brown on the back and sides with a white belly. The skeleton is mainly cartilage. BEHAVIORS The shovelnose sturgeon lives on a gravel or sand bottom in the open channels of large rivers. This fish is capable of reproducing when it reaches a length of 20 to 25 inches (age five to seven years). The female deposits about 200,000 eggs over a gravel or rock bottom in the open channel of a large river. Spawning occurs April through June. The shovelnose sturgeon eats insect larvae (particularly flies and caddisflies), using its flexible sucking mouth to pull them in. ILLINOIS RANGE © Illinois Department of Natural Resources. 2020.

Anderson 2 INTRODUCTION Sturgeon are large, primitive fishes that mature late, are long-lived, and occur in both freshwater and marine systems throughout the world. The bibliography presented here consists of 288 references divided into systematics and distribution, biology, management, morphology, physiology, and fish health for 23 species of the genera Acipenser, Huso, Pseudoscaphirhynchus, and Scaphirhvnchus. In the biology section, references are further subdivided into general biology, reproduction, feeding and locomotion, early life history, and age and growth. In the management section, references are subdivided into fishery history, population dynamics, and cultural practices. Within each section references are arranged in alphabetical order by the author's surname. 3 SYSTEMATICS AND DISTRIBUTION Bailey, R. M., and F. B. Cross. 1954.

    FINAL PERFORMANCE REPORT Federal Aid Grant No. F13AF01276 (T-68-R-1) Determining current distribution, movement, and habitat use of Shovelnose Sturgeon in Oklahoma waters. Oklahoma Department of Wildlife Conservation Grant Period: September 1, 2013 - August 31, 2018 Report Period: September 1, 2013 - November 30, 2017 (Ended Early) FINAL PERFORMANCE REPORT State: Oklahoma Grant Number: F13AF01276 (T-68-R-1) Grant Program: State Wildlife Grants Grant Title: Determining current distribution, movement, and habitat use of Shovelnose Sturgeon in Oklahoma waters Grant Period: September 1, 2013 - August 31, 2018 Report Period: September 1, 2013 - November 30, 2017 (granted closed early) Project Leader: Josh Johnston, Regional Supervisor of Fisheries, Oklahoma Department of Wildlife Conservation A. OBJECTIVE: The specific objectives are 1) Determine the current distribution of Shovelnose Sturgeon in Oklahoma using a random and systematic sampling approach; 2) Develop and validate a distribution model by sampling predicted areas previously un-sampled; and 3) Identify habitat selection by Shovelnose Sturgeon in Oklahoma during warm and cold-water periods. B. SUMMARY OF PROGRESS: Abstract: Shovelnose Sturgeon is the most abundant sturgeon in North America, but their abundance has declined over the past century. Extirpations have occurred in some areas, and some range-edge populations are now isolated. Isolated populations of Shovelnose Sturgeon in the Arkansas River and Red River basins of the southern Great Plains represent the southwest extent
