The recognition of previous termrecreationalnext term and conservation benefits of coral reefs globally provides a sound economic rationale for their management. The value of previous termrecreationalnext term and conservation benefits of coral reefs along the Lingayen Gulf, Bolinao, Philippines is evaluated using travel cost and contingent valuation methods, respectively.
Aquaculture species are being domesticated and improved through genetic enhancement. Despite the benefits of improved fish in terms of increased production, there are risks associated with conservation of biodiversity when the introduced strains/species escape in natural waters. This is especially important in Africa which is one of the world’s repository of diverse freshwater fish fauna and home to native tilapias.
A large proportion of the contributions to the ICES Theme Session on "Trophic models in aquatic ecosystems" is presented, together with papers of a number of scientists and very experienced ecosystem modellers.
The Catalogue of Life, created by Species 2000 and the Integrated Taxonomic Information System, has the ambitious aim of creating a uniform and validated index of the world’s known species for use as a practical tool in inventorying and monitoring biodiversity worldwide. This is achieved by accessing an array of taxonomic databases created and made available by individual, project and institutional custodians through taxonomic and biodiversity initiatives. A standard data set is delivered for every known species, drawn from Species 2000 contributing databases.
Review of the experiences and lessons from multi-country, multi-site projects undertaken by ICLARM. Based onthe review the volume outlines the key factors to be considered in designing and implementing such projects. It presents guidelines for selecting countries and sites to suit the objectives of the projects, as well as for ensuring successful achievement of these objectives in partnership with local organizations and other scientific institutions.
Despite the considerable potential for continued growth in cyprinid aquaculture production in Asia, there are increasing concerns about the status of native cyprinids especially those that are important to aquaculture in the region. During the last 25 years, Asia has seen remarkable economic and social transformation that consequently has resulted in increases in developmental activities and enormous pressure on the region’s natural resources.
Tilapias, because of the low cost and relative ease of their production, are a potential food fish staple for many people in tropical countries and a globally traded commodity. This volume of symposium proceedings shows a strong interest in production systems research and a dawning interest in socioeconomic research. Both of these fields of research are expected to receive much greater attention in the future as the economic and market importance of tilapia increases and as we seek to understand better the distribution of benefits of the different production technologies.
