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 and paddlefishes (Acipenseriformes) 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 color illustrations. It value will be timeless.
The book is structured into four sections, comprising:
- An introduction, with gross morphology, general ecology, systematics of sturgeons, and the sturgeon hybrids, as well as a revised key to the species.
- A species section, with detailed description of all known species worldwide including their description, their distribution, their ecology, and their economy.
- An aquaculture section, including the different methods of handling, propagation, incubation, feeding, management of tanks, ponds and cages. As well as an overview on fisheries techniques, stock management, product processing.

The Bibliography of Acipenseriformes: With over 10000 References.
By Martin Hochleithner, Jörn Gessner and Sergej Podushka.
The most important and comprehensive bibliography about Acipenseriformes.
Available as searchable electronic version (on CD-ROM or USB-stick) or printed book version (over 500 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. It is the most important and comprehensive bibliography about Acipenseriformes, and includes nearly all publications from around the world. The numerous references are listed alphabetically by author(s) and chronologically by year(s), as the original title. They are cross-indexed to species and headings. 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 degradation, 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.

Aquaculture Technology: Fishfarming & Equipment (Catalog).
By Martin Hochleithner.
A product catalog of the company AquaTech.
PDF-file or Softcover, 80 pages.

The need and demand for fish and seafood are rising continually worldwide, and wild fish stocks are steadily becoming scarcer and scarcer. Aquaculture is a young and innovative part of the economy with high growth rates and secured prospects. The future of fish production requires that water be used as economically as possible, and that waste products be removed safely with the lowest possible energy consumption. Environmental legislation is progressively reducing the possibilities of open water fish production and existing fish farms are confronted with directives for purifying their waste discharges. This has accelerated the development of intensive, water-saving systems for fish production, which do not depend upon natural environmental factors. Through improvements to these techniques, very efficient and cost effective systems for both fresh- and seawater where developed. Because of extensive work and many years’ experience in fish farming, it's know how important it is to have secure, stable, safe and effective units and equipment. This knowledge is apparent in these systems, machines, instruments and accessories. Offered is a complete program for aquaculture from the supply of single components like: incubation-, holding-, feeding-, aerating-, and processing-systems, to complete hatcheries and grow-out systems suitable for many species. If preferred, even complete, all-inclusive services – from consulting and planning to training and marketing, etc. Use this extensive experience and know-how to secure your success!
