    A regional shellfish hatchery for the Wider Caribbean - Assessing its feasibility and sustainability

    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.

    Installation and operation of a modular bivalve hatchery. (Printed version contains CD-ROM) 2007

    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.

    Pearls, one of the highly esteemed gems, are very valuable due to the high demand and prices for them. Several countries bordering the Indian and Pacific Oceans and some countries along the Eastern Atlantic Ocean have pearl oyster resources. Many of these countries, particularly those in Asia, are very much interested in pearl oyster farming and pearl culture. Japan stands foremost in the two fields having developed technologies and innovations in the field. The techniques of pearl oyster farm ing and pearl culture are not widely known. There is a need to promote more widely the techniques and relevant information on the bionomics of pearl oysters. In India, interest in pearl culture began at the start of this century. Several studies have been conducted by the Madras Fisheries Department in the 1930s. In 1972, the Central Marine Fisheries Research Institute (CMFRI) took up intensive research on pearl culture at Tuticorin achieving a breakthrough in July 1973 when it produced free s pherical cultured pearls by employing the mantle graft implementation technique. Since then intensive research has been carried out by the Institute on pearl formation, pearl oyster biology and ecology, and hatchery techniques for production of pearl oyster seed. Considerable information of applied value has been obtained. The development of the pearl oyster hatchery technology in India in 1981 opened the way for large and commercial scale culture of this bivalve species. Based on the technica l know-how provided by the CMFRI, a company has been established at Tuticorin to produce cultured pearls.
