Book (stand-alone)Manual / guideManual on hatchery production of seabass and gilthead seabream- Volume 1 1999
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 two decades. The substantial increase in production levels of these two high value species 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 built 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 the wild. 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 cost 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. The preparation of the manual has taken several years, also due to the progress of the sector that led to substantial revisions of sections. This has lengthened its preparation beyond what was originally expected. The manual is not intended to be the final word on hatchery production but rather a publication on how the industry produces in the late nineties. We prefe rred to include proven procedures rather than orient this publication to research on hatchery produced fry, as there is plenty of academic literature on this subject. The manual has been divided in two volumes, with this first one divided in three parts. The first part dealing with the historical background which has led to the present status of this practice, and a discussion of the main factors that affect fish seed production. -
Book (series)Technical studyManual on the Production and Use of Live Food for Aquaculture 1996
Also available in:
No results found.The cultivation of fish and shellfish larvae under controlled hatchery conditions requires not only the development of specific culture techniques, but in most cases also the production and use of live food organisms as feed for the developing larvae. The present manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical pro perties and feeding methods. The manual is divided into different sections according to the major groups of live food organisms used in aquaculture, namely micro-algae, rotifers, Artemia, natural zooplankton, and copepods, nematodes and trochophores. -
Book (series)Technical studyInstallation and operation of a modular bivalve hatchery. (Printed version contains CD-ROM) 2007
Also available in:
No results found.Limiting factors such as minimal capital investment, lack of technical support or expertise and available physical space may put severe restrictions on setting up a hatchery. Not all investors have the means or the will to take the risk to support a large commercial aquaculture operation without substantial proof of its production capacity. For these reasons, the setup of an inexpensive modular hatchery may be a simpler option to the start-up of a large commercial operation, or may be sufficient to the needs of a smaller operation. This manual was written for those interested in establishing a bivalve hatchery, with minimal experience in this activity, limited technical support and restricted access to information. The manual stands as an entity, providing not only the technicalities of setting up and operating a hatchery, but also makes some of the scientific background, deemed useful to the aquaculturist, readily accessible. The manual is divided into chapters for each stage of reari ng: broodstock conditioning, algal culture, hatchery, nursery, growout and economic considerations. The first five chapters include both the physical requirements and culture considerations and procedures for the relevant rearing stage. The final chapter on economic considerations provides an insight into the labour involved for each stage of production, along with a list of equipment and supplies, which may be used as a template for a new installation.
