Book (series)التفريغ الاصطناعي الصدفيات - دليل عملي 2007This manual is a synthesis of current methodologies pertinent to the intensive hatchery culture of bivalve molluscs. It encompasses similarities and differences in approach in rearing clams, oysters and scallops in different climatic zones. All aspects of the culture process are described together with basic considerations in choosing a site for hatchery development and in the design of a suitable facility. The content also includes the post-hatchery handling of larvae in remote setting and also of spat in both land- and sea-based nurseries. It is intended to assist both technicians entering this field as well as entrepreneurs researching investment opportunities in bivalve culture.

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.

Book (series)Hatchery-based seed production of the Japanese scallop, Mizuhopecten yessoensis 2022
Also available in:
No results found.This guide is intended as a standalone practical manual for the culture of the Japanese or Yesso scallop, Mizuhopecten yessoensis. It is written for hatchery staff as a reference for daily operating procedures and for developing a site-specific and resource-specific seed production strategy. To that end, the whole production cycle is addressed, from broodstock conditioning to transport of seed to the farm. It is the aquaculturist’s decision as to whether all stages are required to achieve the target production in a given site and hatchery facility. Standard and more recent emerging techniques are included where possible, for the equal benefit of low and high technological operations. The manual starts with a brief overview of the anatomy and morphology of the scallop and describes the main organs of the adult specimen and the stages of its life cycle; the anticipated development time between each stage throughout its culture is added for the aquaculturist’s benefit. This is followed by a chapter on the culture of live microalgae for food; different approaches to culturing large-scale microalgae are given, including traditional batch culture to the more recent newly designed photobioreactors. Protocols are given from stock to intermediate microalgal cultures for the inoculation of large-scale vessels. The integration of probiotic bacteria as an alternative to standard antimicrobial drugs is described in a separate chapter; this is a critical component of this manual as it is a current and important shift in sustaining optimal larval and spat performance. The need for biosecurity in a full cycle hatchery operation is emphasized and conceptually illustrated. The culture protocols for scallops start with the holding and conditioning of broodstock; assessments of the gametogenic stage, the manipulation of holding temperature to maintain and/or enhance gametogenesis and food requirements are all discussed to ensure the supply of broodstock for spawning when needed. Larval culture is one of the longest chapter of this manual and describes rearing in both static and flow-through systems with the expected growth and survival rate for the Japanese scallop. Post-larval culture in the nursery chapter is divided into early post-set up to Day-14, rearing of 1 mm spat and raising seed up to 5 mm or more in a land-based environment. The final chapter discusses different strategies affecting the time and size at which seed are transferred out of the nursery facility to either intermediate outdoor nurseries or to the farm sites. -
