Series: The Siberian Sturgeon (Acipenser baerii, Brandt, 1869) Volume: 2
590 pages, 164 colour & 67 b/w photos and illustrations, 30 tables
The Siberian sturgeon, Acipenser baerii Brandt 1869 is the most widely farmed sturgeon species. Continuing from Volume 1, which focuses on the biology of the species, the present Volume 2 in turn examines farming aspects.
It is divided into six parts, the first of which deals with reproduction and early ontogenesis, i.e. reproductive cycles, controlled reproduction, sperm cryoconservation, and weaning of larvae. The second covers the growing phase with a focus on food and feeding (management, fish meal replacement, potential endocrine disruptions, usefulness of prebiotics and immunostimulants, and nitrogen excretion). Production-related data are the focus of the third part and include: characteristics (countries, structures of production, evolution in production, economic features) of the gross production of the species (meat and caviar) worldwide, a method for assessing the quality of caviars, off-flavors management, and an example of production of fingerlings for restocking. Part four addresses selected long-term management issues: genetic variability of brood stocks, genome manipulation and sex control, and the advantages of hybrids. The next three chapters constitute the fifth part, which is devoted to health status (immunology and welfare). In closing, the absence of ecological risks of introducing the species in non-native waters is shown using two long-term documented examples (Russia and France). Three methodological chapters round out The Siberian Sturgeon (Acipenser baerii, Brandt, 1869), Volume 2: Farming, covering: in vitro incubation of ovarian follicles, a richly illustrated library of echographies and photos, and a detailed presentation of oxygen demand studies.

Patrick Williot spent the three quarters of its professional career primarily to take the challenge of the disappearing of the European sturgeon, Acipenser sturio. To achieve this task, he mobilized all the means of research (both applied and fundamental lines, biological model, national and international cooperation's), and management (private-public partnership, transfer of know-how, installation of a new experimental facility, search for regular financial support). Patrick has developed his activity around the couple [aquaculture-conservation biology]. Patrick stimulated the development of sturgeon farming primarily in France based on the biological model, the Siberian sturgeon, Acipenser baerii. He has been the kingpin of the First International Symposium on sturgeon held in Bordeaux in 1989 where he launched the concept of the international association for the conservation of sturgeons which was installed (the WSCS; wscs.info) some year later. Later on, he edited the peer-reviewed proceedings (Acipenser), served as scientific committee member of further International symposia on sturgeons as well as the sturgeon specialist group of the IUCN, and organized other symposia and workshops. He succeeded in obtaining for the first time the controlled reproduction of farmed European sturgeon in 2007 which avoided the species from a complete disappearing and opened the door for a restoration. Patrick initiated and carried out the editing of Biology and Conservation of the European Sturgeon (2011) and on the biology and farming of the Siberian sturgeon which is in process. Patrick published about 90 papers in peer-reviewed journals or books.
Doctor of the University of Strasbourg, Guy Nonnotte was appointed research officer at the CNRS in the Laboratory of Comparative Physiology of the Regulations at F-Strasbourg in 1974. He conducted original research especially on cutaneous respiration and skin ionic exchanges on many models of freshwater and sea-water fish. In 1986, he joined the Laboratory of Neurobiology and Compared Physiolgy, (CNRS and University of Bordeaux I, F-Arcachon) and pursued research on extracellular acid-base balance and cell volume regulation in fish exposed to environmental changes and pollutants with a specific interest for the model " Siberian sturgeon ". He supervised a thesis on the toxicity of ammonia for the Siberian sturgeon in collaboration with Dr. Patrick Williot. He took also the opportunity to initiate an important collaboration concerning the respiration, the acid-base balance and the physiological effects of environmental stress for the Siberian sturgeon with the Laboratory of Animal Physiology, F-Brest. In 1994, he was appointed Professor of Animal Physiology (fish physiology) at the University of Brest (France) and managed the Laboratory of Cellular Biology and Physiology. He wrote numerous publications in international reviews and managed several thesis on fish physiology. He was also appointed for numerous evaluations and jury of thesis by INRA, IFREMER, INSERM and CNRS. In 2002, he was designed Vice-President of the University of Brest, responsible of the research and in 2007, Emeritus-Professor of the Brest University.
Denise Vizziano-Cantonnet is a Professor of the Facultad de Ciencias at the Universidad de la Republica Oriental del Uruguay (UdelaR) and at the Post-Graduate program Programa de Desarrollo de Ciencias Basicas (PEDECIBA). She is Researcher of the Government System of National Researcher (ANII) and Head of the Department of Animal Biology (UdelaR). She is Doctor of the University of Rennes I (U-Rennes I, France) and made a post-doctoral stay at the INRA of Rennes (France). She worked as Invited Professor at U-Rennes I. She conducted original research on reproductive endrocrinology of fish working in different species of commercial importance as trouts, silverside, croakers and developed for 20 years a Training Course on Reproductibe Phsyiology of Fish for Latino American students promoting the development of this new area of research in the Latin America. She was invited as Professor at different Universities of Latin America (Argentina, Brazil, Chile, Colombia, Peru) interested to develop Endocrinology of Reproduction of native species key for fish farming. She started to work in Siberian sturgeons when the producers contacted the University to reproduce the species in Uruguay. The first reproduction in captivity of the south hemisphere has been done in Uruguay together with Dr. Patrick Williot by applying the methodology developed by this Researcher in the CEMAGREF (France). She started the first worldwide investigations in the molecular basis of sex differentiation in sturgeons and built a complete gonadal transcriptome of Siberian sturgeons in order to search the master gene for sex determination and genes involved in sex differentiation. In cooperation with specialists on fish evolution (Dr. Jean Nicolas Volff and Dr. Frederic Brunet, University of Lyon) a first study on retrotrasposons has been made using the gonadal transcriptome. A multi-tissue transcriptome is recently built for Siberian sturgeons in cooperation with Ing. Christophe Klopp (Inra, Toulouse) and the team of Dr. Vizziano are now searching for a genetic sex marker that will improve the fundamental research and will have an impact in sturgeon production.
