New books:

The Siberian Sturgeon (Acipenser baerii Brandt, 1869)
By Patrick Williot, Guy Nonnotte, Denise Vizziano-Cantonnet and Mikhail Chebanov.
Hardcover, 780 pages.

This two-volume book set focuses on the Siberian sturgeon. Acipenser baerii one of the "still existing” sturgeon species, is a native species of the Siberian catchments, where – as in many other parts of the world – the sturgeon populations are now threatened. Sturgeon farming practices targeting caviar and meat production have been expanding worldwide since the 1990s, and have seen a further increase since the turn of the century. Among the handful of sturgeon species used for significant production, the most dominant is the Siberian sturgeon. Given its peculiar phylogenetic position as a chondrostei and its use as a biological model in some countries, the species has also attracted the attention of biologists. 
The aim of the editors was to provide for the first time a comprehensive and updated synthesis regarding the farming-related biology of the Siberian sturgeon. In light of the abundance of material, it has been divided into two volumes, with a focus on biology and farming, respectively. The main parts of Volume 1 are biology and ecology, biology and physiology of reproduction, and ecophysiology. In turn, Volume 2 is divided into six parts: reproduction and early ontogenesis, growing, global production, long-term management of brood stock, state of health through welfare and immunology, and ecological risks of installation in non-native waters, illustrated by two long-term documented examples in Russia and France.

AUTOMATIC FEEDERS with integrated battery

This independent feeders where developed in Austria and are successfully used since more than 20 years in small to large fish farms. The user friendly feeding system with patented mechanism (spindle) allows easy feeding and supply of food to day- and night active fish or other animals. They can be powered by usual (Mono D) batteries (3 to 12 V/DC), which are supplied with the feeder. Because of the optimized system, the batteries have a long self-live, depending on feeding times and durance, usually about one season (often also over 1 year). The timer clock with battery tester, which is integrated in the hopper, allows exact settings of feeding times and pauses. The feed supply can be regulated by a turn-able knob and ranges from about 1 to 500 g per hour. Standard particle or pellet sizes of feeds can range from 1 to 5 mm, smaller or larger food particles (also corn or other seeds) are possible optionally. The robust, grey plastic containers (made from polypropylene) guarantee for a long life of the feeder. The standard feeders range from hoppers with a volume of 10 to 260 litre (larger hoppers are possible on request). The larger feeders (from 40 litre volume onward) are also available with an integrated ejector-mechanism, which ejects the dry-food 3-6 m (optionally up to 8-12 m) in front of the feeder. The feeder is usually placed on the edge of a tank or above a dock and fixed via the two mounting holes on the sides. Optionally photovoltaic panels are available. All feeders are also available without batteries, and with or without timer, for the connection to an electric network with transformer (220 V/AC to 12 or 24 V/DC).

Paddlefish Aquaculture
By Steven D. Mims and William L. Shelton (Authors), Hardcover, 320 pages.

Paddlefish have become of increasing interest to the aquaculture community in recent years, particularly as a potential new source of seafood and caviar. Native to North America, paddlefish (Polyodon spathula) show great promise both domestically and internationally as a commercially viable farmed species. This book examines all aspects of the biology and culture of these fish, exploring their physiology, production, end products and the economics underlying a successful paddlefish operation. Chapters specifically cover paddlefish biology, propagation and early culture techniques, production for meat and caviar, international culture and history, paddlefish food products, bioaccumulants of contaminants in paddlefish, parasites and diseases, and the economics of paddlefish aquaculture. Paddlefish Aquaculture is a timely practical reference for researchers and producers interested in this species.

Biology and Culture of Percid Fishes: Principles and Practices
By Patrick Kestemont, Konrad Dabrowski, Robert C. Summerfelt (Editors), et al., Hardcover, 901 pages.

This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured.

Ultraviolett Sterilizers -

This ultra violett sterilizers utilize germicidal lamps which emit UV-C with an effective wavelength of 254 nm, lethal for up to 99.9 % of bacteria, viruses and other microorganisms present in the water. This ultraviolet technology is one of the most effective method of water treatment and purification, without using any chemicals. The effective UV Dose is: UV-Dose (µW.S/cm2) = UV-Intensity (µW/cm2) x UV-Exposure (S). The maximum operating pressure is 7 bar and the average lamp life is about 9000 hours. The supplied (internal or external) ballast has an indicator to check the function of the lamp.
The immersion UV-sterilizers are used under water, particularly in water tanks to prevent secondary infection and pollution. They have a diameter of min. 25 mm and max. 40 mm, and are easily installed in any tank so that operation is very simpe.
The inline UV-sterilizers are used out of the water, particularely in hatcheries to prevebt primary infection and pollution. The inside wall of the stainless steel chamber is polished, which helps to improve the efficiency of disinfection by reflection.

The following immersion sterilizers are available as standard:

The Sturgeons and Paddlefishes (Acipenseriformes) of the World: Biology and Aquaculture
By Martin Hochleithner and Jörn Gessner.
An extended, updated and reviewed third edition. Soft- or Hardcover, 248 pages.

The breeding and culture of sturgeons in captivity has advanced rapidly over the past several years. With recent developments, the requirements of the industry have changed, and the techniques used have also evolved and been adapted to meet these changing needs. Based on experience gained in the the former USSR, new technologies have been developed, and the background of sturgeon biology has been enlightened in many respects. This compendium is designed to close the information gap between scientists and practitioners. Its appeal will be far reaching since biologists, field technicians, hatchery operators and fish farmers, fisherman and fish enthusiasts, will all find a wealth of practical information relevant to their field of interest. The book has the style of a species synopsis coupled with everything anyone needs to know about the reproduction and culture of acipenserid fishes. It summarizes current knowledge on all sturgeon and paddlefish species worldwide and presents it as a practitioner-oriented working guide. It draws on the experience and research findings of the authors gained over more than two decades. The new, third edition has been updated, extended, and reviewed, and includes many new colour illustrations. It value will be timeless.

Sturgeon Fishes (Acipenseriformes): Science as Art
By Paul Vecsei and Martin Hochleithner.
Hardcover, 120 pages.

Illustrator and biologist Paul Vecsei and aquaculture specialist Martin Hochleithner are both internationaly well known experts in the field of sturgeon research and culture. In this volume, they showcase the numerous sturgeon species and highlight the plasticity of sturgeon morphology (both within and between species) using more than 130 detailed illustrations and many summary tables. The material in this book is the culmination of 5000 hours of scientific illustrations. Each illustration is of an individual fish and is extremely accurate. They are made in the technique of pointillism, a known fine-art technique. Each picture is made by small dots, which, when viewed for a distance, creates a very detailed rendition of shape and form. Sturgeon afectionados, sturgeon experts and art lovers will appreciate the collection of illustrations in this unique work.

The BIBLIOGRAPHY of Acipenseriformes: With over 10000 References
By Martin Hochleithner, Jörn Gessner and Sergej Podushka.
Available as searchable electronic version (on CD-ROM) or printed book version (over 500 pages).

This bibliography, which includes nearly all publications from around the world, and covers all Acipenseriforms and a range of topics, is intended to serve as a ready reference for researchers, fisheries managers, aquaculturists and conservationists who work with this ancient fish group. The numerous references are listed alphabetically by author(s) and chronologically by year(s), as the original title. Almost all sturgeon- and paddlefish species are threatened or endangered. Information on them is by no means complete, whether in fields related to sturgeon culture, biology, ecology or management. Due to the current rate of wild-stock exploitation and environmental degradiation, the availability of new information might prove crucial for their survival. This is an attempt to disseminate information about work carried out to date, and to increase its availability.

The BIBLIOGRAPHY of Acipenseriformes: Update of the 2000's
By Martin Hochleithner, Jörn Gessner, Sergej Podushka, Mohammad Pourkazemi and Qiwei Wei.
An update for the years 2000-2009. Paperback, 280 pages.

This bibliography, which covers all Acipenseriforms and a range of topics, is intended to serve as a ready reference for researchers, fisheries managers, aquaculturists and conservationists who work with this ancient fish group. Almost all sturgeon- and paddlefish species are threatened or endangered. Information on them in any field is by no means complete, whether related to sturgeon culture, biology, ecology or management. In many aspects sturgeon biology is very different from that of other fishes, and techniques suitable for other species may not work with them. Due to the current rate of wild-stock exploitation, the availability of new information might prove crucial for their survival. This is an attempt to disseminate information about work carried out to date, and to increase its availability. This is the most important and comprehensive bibliography about Acipenseriformes, and includes nearly all publications from around the world. The references are listed alphabetically by author(s) and chronologically by year(s). This update includes the years 2000-2009. This update is allready included in the bibliography on CD-ROM.

Multichannel Commander System

This multichannel process control and management system is a very versatile instrument that can be used as a stand-alone wirless and solar powered multi channel controller for cages, ponds, tanks and raceways, etc. If there are more than 1 monitor units and a base station receiver, then the system automatically configures as a network and sends the information by low powered wireless communication to the base station. The base station has 2 alarm outputs, so it is easy to connect it to a telephone dialer or a local alarm. The base station connects to a PC via a USB, so now you have all the information displayed on your PC and all the results can be data logged. You can add up to 50 monitor units onto the one base unit, to make a 100 channel network with no wires and no installation costs. This makes for a really low cost simple system and for the first time provides a package ideal for cages, ponds or for any installation that can not use wires. In the event that you get hit with lightening, then generally only one unit will be affected, and if it can not be repaired on-site then you simply send the faulty unit back and replace with a working unit. This means that you are in control of your own system and not dependent on service engineers.
The base station is designed to sit in an office or control room and is connected to a PC by means of a USB cable. The base station communicates with all the transmitters, collects the information and sends onto the PC to data log the information and view the data. The base station has two alarm/control relays so if any one or more of the probes detects a problem, the relays can be activated to trigger your alarm system. The PC does not need to be on for the system to control or alarm. The alarm condition and probe location will be displayed on the base station LCD. One Base station can support up to 50 oxygen transmitters and 100 oxygen and temperature probes.
The transmitter station is a solar powered wireless radio transmitter fitted with LCD display for two oxygen probes, two temperature sensors, two digital inputs and fitted with two relay control or alarm out-puts. The unit will transmit over a distance of at least 300 m. If longer distances are required a repeater may be fitted to take the distance up to 3 km or more. The transmitter is in a self contained IP65 enclosure with its own battery and solar cells. The battery alone will power the unit for 3-6 months, but with the solar cells it will not require a battery change for at least 5 years. A 230 VAC/12 VDC uninteruptable power supply, rated at 2 amps with a 5 amp internal back-up battery for the transmitter module which will the battery will keep running for around 30 days, is available as acessoire.
The robust and easy to use (60 mm large) oxygen probe is a self polarising membrane covered galvanic cell that generates an electrical signal proportional to the oxygen pressure it senses, no matter whether it is in water, air or another medium. It is connected using ordinary 2-core cable, which can have any length (up to 1000 m) and does not need an external supply because it makes its own electricity. Cleaning the membrane (with a cloth or tissue) is, apart from an occasional calibration, the only routine maintenance necessary. The probes are robust, reliable and as stable as an optical probe but at a much lower price.

Base station, EUR 990,-
Transmitter station, EUR 990,-
Oxygen and temperature probe, EUR 290,-

Biology and Conservation of the European Sturgeon Acipenser sturio L. 1758: The Reunion of the European and Atlantic Sturgeons
By Patrick Williot, Eric Rochard, Nathalie Desse-Berset, Frank Kirschbaum and Jörn Gessner. Hardcover, 696 pages. (October 2011)

The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen’s organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.
