Coral reefs provide a variety of services to the continental and island people of the Caribbean. They provide, for example, coastline protection, fish harvests, and, more recently, increased tourism. But reefs have also suffered a long history of associated destruction, resulting from, amongst other things, over-fishing, deteriorating environmental conditions (arising from both local and remote societal stresses), factors linked to globalization (trade fixated on generating foreign exchange through fish exports and coastal tourism), and natural factors such as hurricanes.
An Expert Consultation on Biosafety and Environmental Impact of Genetic Enhancement and Introduction of Improved Tilapia strains/ Alien species in Africa, was convened in Nairobi, Kenya from 20-23 February 2002 to discuss and develop guidelines that will foster the development of aquaculture while maintaining biodiversity. The meeting was attended by aquaculturists, geneticists and conservation specialists from Africa and from international organizations.
The condition of mangroves pre- and post- tsunami and the socioeconomic role of mangrove forests in the livelihoods of coastal communities along the west coast of Aceh province, Indonesia are examined. The findings indicate that community livelihoods are significantly linked to the mangrove ecosystem. However, most of the mangrove rehabilitation programs are conservation orientated, aimed primarily at land conservation, and are not necessarily linked with livelihood options for local people or integrated resource management.
Africa has been the source of alien species that are widely used in aquaculture and fisheries in many parts of the world, but African aquaculture has not benefited greatly either from the domestication of African species or the introduction of improved breed from elsewhere. In efforts to develop African aquaculture further, there is a desire to reintroduce genetically improved tilapia (primarily Oreochromis niloticus) back into Africa. However, there are risks to native African aquatic biodiversity that must be dealt within the re-introduction of African species.
Integrated Agriculture-Aquaculture (IAA) is essentially diversification of agriculture, leading to synergisms among sub-systems resulting in a higher productivity from land/water area under the farmers' control. One method of achieving this is adding a pond culture component to a farm system, basically to receive and utilize the nutrient inputs from the latter. The second method is physically integrating aquaculture into the other systems by modifying the farm design and operations.
In comparison to the rest of the world, aquaculture in Africa is fairly insignificant. The continent as a whole contributed a mere 0.9 per cent (404 571 t) to the total world aquaculture production in 2000. The African continent, however, exhibits considerable potential in terms of land and water and in regard to inland, coastal and offshore resources. Genetic improvement of tilapias has a role to play in order to increase aquaculture production.
This book contains six chapters 1)Introduction 2) Status of carp genetic resources 3)Brood stock management and artificial breeding of carp species in hatcheries 4)A breeding plan for cultured minor carp species 5)A breeding plan for cultured major carp species 6)Breeding and conservation of endangered carp species
Report of a 1992 workshop. Includes discussion papers on population genetics, broodstock establishment, preservation of biodiversity, hatchery procedures, and identifying strains; country papers from Australia, Fiji, Palau, Philippines and the Solomon Islands; discussion sessions and recommendations.
Naturally occurring fish genetic resources are of great importance for fisheries and aquaculture. Fish farmers and fishers face a future in which the diversity of their basic resources is under threat and the genetic composition of these resources will be increasingly reliant on human protection and manipulation. Fish genetic resources research, information and training in the context of existing and future activities are discussed.
The four sea turtle species found in Malaysia are the leatherback, olive ridley, green and hawksbill. The threats to these species are acute. Populations of leatherback, olive ridley and hawksbill turtles are on the brink of collapse – threatening a biodiversity crisis in Malaysia and the region. On 16-17 August 2004, a workshop was convened in Kijal, Terengganu, to chart new directions in the conservation of Malaysia’s critically endangered sea turtles and to reverse population decline.
