Book (series)A regional shellfish hatchery for the Wider Caribbean - Assessing its feasibility and sustainability
FAO Regional Technical Workshop 18-21 October 2010, Kingston, Jamaica
2011Also available in:
No results found.It is widely recognized that the development of aquaculture in the Wider Caribbean region is inhibited, in part, by the lack of technical expertise, infrastructure, capital investment and human resources. Furthermore, seed supply for native species relies, for the most part, on natural collection, subject to natural population abundance with wide yearly variations. This situation has led to the current trend of culturing more readily available exotic species, but with a potentially undesirable i mpact on the natural environment. The centralizing of resources available in the region into a shared facility has been recommended by several expert meetings over the past 20 years. The establishment of a regional hatchery facility, supporting sustainable aquaculture through the seed production of native molluscan species was discussed at the FAO workshop ¿Regional shellfish hatchery: A feasibility study¿ held in New Kingston, Jamaica, in October 2010, by representatives of Caribbean government s and experts in the field. Molluscan species are particularly targeted due to their culture potential in terms of known techniques, simple grow-out technology and low impact on surrounding environment. It is proposed that a regional molluscan hatchery would produce seed for sale and distribution to grow-out operations in the region as well as provide technical support for the research on new species. The current document summarizes the findings of the workshop and outlines four follow-up recomm endations on steps required for the successful implementation of a regional facility. The positive response of participating Caribbean governments demonstrates the current political will for sustainable aquaculture growth in the region, supported by several national plans including the Caribbean Regional Fisheries Mechanism Strategic Plan. -
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)Bivalve depuration: fundamental and practical aspects 2008World bivalve production and consumption has increased significantly in recent years, from a combined total for wild catch and aquaculture of approximately 10.7 million tonnes in 1999 to 14 million tonnes in 2006. Furthermore, the development of freight by air and sea and preservation techniques have enabled consumers, in different parts of the world, to enjoy eating bivalves produced in distant waters. Such developments in distribution and trade have in turn led to emerging challenges for consumer protection, particularly in relation to the safety of bivalves from pathogenic micro-organisms. Several species of bivalves are often consumed live or raw (e.g. oysters), or lightly cooked (e.g. mussels) which make them a high risk food product category requiring proper control measures to eliminate or reduce to acceptable levels potential biological, chemical and physical hazards. This document is intended to provide a basic introduction to the public health problems t hat can be associated with shellfish consumption and to provide guidance to the bivalve industry as to how a depuration centre, and the associated systems, should be planned, constructed and operated. It is mainly targeted at new operators or those with limited experience, as well as fishery and public health officers who deal with the bivalve industry. This is of particular importance for several developing countries, where the bivalve industry is expanding quickly with the aim of win ning an ever larger share of the bivalve international market.
