Seeking to address current declines in sturgeon and paddlefish populations across North America, NASPS is dedicated to promoting the conservation and restoration of these species by developing and advancing research pertaining to their biology, management, and utilization. Distributing scientific, cultural, and historical information related to sturgeon and paddlefish in North America and encouraging the inclusion of sturgeon and paddlefish fisheries science in college and continuing education curricula is critical to achieving these objectives. As such, NASPS recognizes the importance of engaging NASPS members, local, national, and international government organizations, educational institutions, non-governmental

  • Life History and Population Dynamics of Lake Sturgeon
    LIFE HISTORY AND POPULATION DYNAMICS OF LAKE STURGEON, Acipenser fulvescens, IN THE MUSKEGON RIVER, MICHIGAN by Paul Joseph Vecsei (Under the direction of Douglas L. Peterson) ABSTRACT The lake sturgeon was once abundant throughout Lake Michigan with an estimated 11 million fish prior to human exploitation. By the early 1900s, however, most populations had been decimated by severe over-fishing and habitat degradation. Despite recent interests in restoring the species in Lake Michigan, little is known about the current status of remnant populations. The primary objectives of this study were to estimate annual spawning stock abundance and to identify potential spawning habitat for lake sturgeon on the Muskegon River, Michigan. To capture adult lake sturgeon, I used large-mesh, bottom-set gill nets deployed at the mouth of the Muskegon River from mid- March through May, 2002-2005. Radio telemetry was used to monitor seasonal movements and to identify likely spawning habitats. Sampling for larval lake sturgeon was conducted in May of each year using D-frame drift nets anchored in the mainstream of the river channel. During the 4 years of the study, I expended more than 5000 gill-net hours and captured 59 individual adult lake sturgeon. Larval lake sturgeon were captured in 2 years, suggesting that at least some natural reproduction still occurs. Habitat analysis revealed that the lower Muskegon River likely contains extensive reaches of potential spawning habitat for lake sturgeon. INDEX WORDS: Biology, population dynamics, habitat, lake

  • NORTHERN GREEN STURGEON Acipenser Medirostris (Ayres)
    NORTHERN GREEN STURGEON Acipenser medirostris (Ayres) Status: High Concern. Very little is known about the current size of the single northern green sturgeon population in California. However, habitat degradation and climate change continue to threaten their status. Description: Sturgeons, with their large size, subterminal barbeled mouths, lines of bony plates (scutes), and heterocercal (shark-like) tail, are among the most distinctive of freshwater fishes. Green sturgeon have 8-11 scutes in the dorsal row, 23-30 in the lateral rows, and 7-10 in the bottom rows. The dorsal fin has 33-36 rays, and the anal fin 22-28. They are distinguished from white sturgeon, with which they co-occur, by: (1) having one large scute behind the dorsal and anal fins, (2) having scutes that are sharp and pointed, and (3) having barbels that are closer to the mouth than to the tip of the long, narrow snout (Moyle 2002). Their color is olive-green to pale brown, with an olivaceous stripe on each side and scutes that are paler than the body. Taxonomic Relationships: Green sturgeon were described from San Francisco Bay in 1854 by W. O. Ayres as Acipenser medirostris, the only one of three species he described from the Bay that is still recognized. Green sturgeon are tetraploids and have lower fecundity and larger eggs than most other sturgeon (Gessner et al. 2007). The zoogeographic origin of green sturgeon is uncertain; evidence can be mounted for either an Asian or North American ancestry (Artyukhin et al. 2007). The closest relative is the Asian green sturgeon, Acipenser mikadoi, described from one poorly preserved specimen (Jordan and Snyder 1906).

  • Clean &Unclean Meats
    Clean & Unclean Meats God expects all who desire to have a relationship with Him to live holy lives (Exodus 19:6; 1 Peter 1:15). The Bible says following God’s instructions regarding the meat we eat is one aspect of living a holy life (Leviticus 11:44-47). Modern research indicates that there are health benets to eating only the meat of animals approved by God and avoiding those He labels as unclean. Here is a summation of the clean (acceptable to eat) and unclean (not acceptable to eat) animals found in Leviticus 11 and Deuteronomy 14.

  • Habitat Use of Juvenile Pallid Sturgeon and Shovelnose Sturgeon with Implications for Water-Level Management in a Downstream Reservoir
    North American Journal of Fisheries Management 28:832–843, 2008 [Article] Ó Copyright by the American Fisheries Society 2008 DOI: 10.1577/M07-061.1 Habitat Use of Juvenile Pallid Sturgeon and Shovelnose Sturgeon with Implications for Water-Level Management in a Downstream Reservoir 1 PAUL C. GERRITY* AND CHRISTOPHER S. GUY U.S. Geological Survey, Montana Cooperative Fishery Research Unit, 301 Lewis Hall, Montana State University, Bozeman, Montana 59717, USA WILLIAM M. GARDNER Montana Department of Fish, Wildlife and Parks, Post Office Box 938, 215 Aztec Drive, Lewistown, Montana 59457, USA Abstract.—Natural recruitment of pallid sturgeon Scaphirhynchus albus has not been observed in the Missouri River above Fort Peck Reservoir, Montana, for at least 20 years. To augment the population, age-1 hatchery-reared juvenile pallid sturgeon were released in 1998. The objective of this study was to evaluate the habitat use of these fish and compare it with that of indigenous shovelnose sturgeon S. platorynchus. Twenty- nine juvenile pallid sturgeon and 21 indigenous shovelnose sturgeon were implanted with radio transmitters in 2003 and 2004. The two species showed no differences in habitat use in terms of mean depth, cross-sectional relative depth, longitudinal relative depth, column velocity, bottom velocity, and channel width. However, there were seasonal differences within both species for cross-sectional relative depth, column velocity, and channel width. Both shovelnose sturgeon and juvenile pallid sturgeon were primarily associated with silt and sand substrate. However, shovelnose sturgeon were associated with gravel and cobble substrate more than juvenile pallid sturgeon. Shovelnose sturgeon and juvenile pallid sturgeon both selected reaches without islands and avoided reaches with islands; the two species also selected main-channel habitat and avoided secondary channels.
