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 -

Sturgeons – Contemporaries of Dinosaurs
G.M. PALATNIKOV, R.U. KASIMOV STURGEONS – CONTEMPORARIES OF DINOSAURS BAKU – 2010. INTRODUCTION TheCaspian Sea is abundant with its natural unique gems, the most famous being sturgeons and oil. But, as the old wisdom says, wealth alone will make no one happy, especially if used without thinking of future. All natural resources can be categorized as renewables and nonrenewables. Renewables are such resources that can regenerate through reproduction or through the nature renewal cycles over the time frame comparable with the pace of huuman economical activity. Examples of such resources are sturgeons. Nonrenewables are such resources that cannot regenerate over the natural cycle over the time frame comparable with the pace of human economical activity. Oil reserves are such nonrenewable resources. Oil has now been actively developed and produced. Big money is being spent for the development of hydrocarbon exploration, production and transportation technologies. But hydrocarbon reserves sooner or later will deplete. As for sturgeons, their stock is being gradually decreased because of irrational catch, reduction of feeding and spawning areas, and contamination of the water environment - and oil industry has contributed greatly to it. However, this problem has currently not been addressed properly although preservation of sturgeon reserves requires less investment but promises continuously high profits at all times. Unfortunately, not everyone, including those who live at the Caspian Sea, understands this. Most people have insufficient knowledge about sturgeons, but view sturgeons as a source of food. We will try to inform the readers about the life of this unique fish. We will tell you the following: What are these species that have left such a noticeable footprint in the history of mankind? What y interest (other than being a source of food) do they present? Will they be preserved for future generations, or disappear as did their contemporaries – the dinosaurs? 1 GOING BACK TO HISTORY Sturgeon catching has been known since ancient times. -

Nedoluzhko 1*, Fedor S. Sharko2,3, Svetlana V. Tsygankova2, Eugenia S. Boulygina2, Anna E. Barmintseva4, Anna A. Krasivskaya2, Amina S. Ibragimova2, Natalia M. Gruzdeva2, Sergey M. Rastorguev2,6 & Nikolai S. Mugue4,5,6 The enigmatic and poorly studied sturgeon genus Pseudoscaphirhynchus (Scaphirhynchinae: Acipenseridae) comprises three species: the Amu Darya shovelnose sturgeon (Pseudoscaphirhynchus kaufmanni (Bogdanow)), dwarf Amu Darya shovelnose sturgeon P. hermanni (Kessler), and Syr Darya shovelnose sturgeon (P. fedtschenkoi (Bogdanow). Two species – P. hermanni and P. kaufmanni – are critically endangered due to the Aral Sea area ecological disaster, caused by massive water use for irrigation to support cotton agriculture, subsequent pesticide pollution and habitat degradation. For another species – P. fedtschenkoi – no sightings have been reported since 1960-s and it is believed to be extinct, both in nature and in captivity. In this study, complete mitochondrial (mt) genomes of these three species of Pseudoscaphirhynchus were characterized using Illumina and Sanger sequencing platforms. Phylogenetic analyses showed the signifcant divergence between Amu Darya and Syr Darya freshwater sturgeons and supported the monophyletic origin of the Pseudoscaphirhynchus species. We confrmed that two sympatric Amu Darya species P. kaufmanni and P. hermanni form a single genetic cluster, which may require further morphological and genetic study to assess possible hybridization, intraspecifc variation and taxonomic status and to develop conservation measures to protect these unique fshes. Te animal diversity and classifcation remain complex with new species being continuously discovered and described. -

In addition a draft of an annotated bibliography (Through 2003) was produced (U.S. Fish and Wildlife Service 2004) as background material for the Research and Assessment Needs for Pallid Sturgeon Recovery in the Missouri River meeting in Bloomington, MN, May 18-20, 2004 (Quist et al. 2004). Since that time a considerable number of studies and their publications have added significantly to the knowledge relevant to the aim of recovering the populations of pallid sturgeon. The literature examined for this review is listed in the literature cited section. In addition we have acquired a set of PDF files of this literature. These files are cross referenced with the literature citations in Appendix 1. The goal of this review is to organize this expanding information base and to point out the relevance of individual reports and publications to the hypotheses for pallid sturgeon proposed by the Platte River Recovery Implementation Program (PRRIP). -
