Book (stand-alone)Manual on hatchery production of seabass and gilthead seabream - Volume 2 2005
Also available in:
No results found.Seabass and gilthead seabream are the two marine fish species which have characterized the development of marine aquaculture in the Mediterranean basin in the last three decades. The substantial increase in production levels of these two species, initially of very high value, has been possible thanks to the progressive improvement in the technologies involved in the production of fry in hatcheries. As a result of this technological progress more than one hundred hatcheries have been bu ilt in the Mediterranean basin, working on these and other similar species. At present the farmed production of these two species that is derived from hatchery produced fry is far greater than the supply coming from capture fisheries. The development of these techniques, based originally on Japanese hatchery techniques, has followed its own evolution and has resulted in what could be called a Mediterranean hatchery technology that is still evolving to provide higher quality animals and to reduce the costs of production. This is a dynamic sector but it can be judged that it has reached a level of maturity that merits the production of a manual for hatchery personnel that could be also of interest in parts of the world other than the Mediterranean. The preparation of the manual has taken several years, also due to the progress of the sector that led to substantial revisions of sections. The manual is not intended to be a final word in hatchery design and operation but rather a publication to document how the industry produces. The authors have preferred to include proven procedures and designs rather than to orient this publication to research hatcheries that are not yet the standard of the sector. The manual has been divided in two volumes, of which the first one was finalized in year 2000, and which covered historical background, biology and life history of the two species and especially hatchery production procedures. This second volume is div ided in four parts. -
Book (series)Marketing of aquacultured seabass and seabream from the Mediterranean basin 2007
Also available in:
No results found.Mediterranean finfish species such as the European seabass and the gilthead seabream have, over the last two decades, been attracting considerable attention among aquaculturists and investors. The net result has been a rapid increase in the supply of the finfish to European markets. Accessing these markets with the right product at the right price is a key factor in the success of any commercial aquaculture project. This report describes the current status of the European market for th ese and other finfish species and the major characteristics of marketing farmed fish in the Mediterranean basin. Part 1 of the report gives an overview of the global European market, including developments in finfish production and marketing performance. Part 2 reviews major market traits of the European seabass and the gilthead seabream as well as other finfish including tilapia. It discusses suppliers to Europe, prices, marketing strategies and product types. Part 3 presents importan t European market characteristics such as product quality, consistency of supplies and competitive prices. Part 4 gives key figures regarding aquaculture production by country. Part 5 outlines farming technologies that may be more suited to certain Mediterranean countries and may offer new investment opportunities. -
Book (series)The hatchery culture of bivalves: a practical manual 2004Bivalve mollusc culture is an important and rapidly expanding sector of world aquaculture production, representing approximately 20% of this output at 14 million tonnes in 2000. The majority of production is from natural populations although increasingly stocks are approaching or have exceeded maximum sustainable yields. Enhancement of stocks through the capture and relaying of natural seed in both extensive and intensive forms of culture is common practice worldwide but the reliability of natur al recruitment can never be guaranteed and conflicts over the use of the coastal zone are becoming ever more pressing. A solution to meeting the seed requirements of the bivalve industry, applicable to the production of high unit value species such as clams, oysters and scallops, is hatchery culture. The production of seed through hatchery propagation accounts at the present time for only a small percentage of the total seed requirement but it is likely to become increasingly important as work continues to produce genetically selected strains with desirable characteristics suited to particular conditions. The advent of bivalve hatcheries was in the 1960s in Europe and the U.S. Since those early pioneering days knowledge of the biological requirements of the various species that predominate in worldwide aquaculture production and the technology by which to produce them has and continues to improve. This manual brings together the current state of knowledge in describing the v arious aspects of hatchery culture and production from acquisition of broodstock to the stage at which the seed are of sufficient size to transfer to sea-based growout. Focus is on intensive methodology in purpose built hatchery facilities rather than on more extensive methods of seed production in land-based pond systems. This manual is not intended as a scientific treatise on the subject. Rather, it is practical in nature providing the reader with an insight into what is required in the w ay of resources and details of how to handle and manage the various life history stages of bivalves in the hatchery production cycle.
