Cage culture is an established and profitable aquaculture system in many countries but it is a relatively complex culture system that is still in its infancy in the Africa region. This expert workshop was convened with the aim of identifying the key issues for sustainable cage culture in the region and developing a framework of good management practice. It concluded that although cage aquaculture could be an important development opportunity, it will require an effective policy framework to ensure that structural constraints to development are overcome and that development is both equitable and sustainable.
This publication presents the proceedings of a workshop held in Ghana in 1999 at which experts from Burkina Faso, the Ivory Coast, Ghana, Mali and Zambia presented national reviews summarising developments and research in the field of irrigation and aquaculture (IIA) activities. The workshop proposed the establishment of a regional IIA network for Africa and considered its objectives, structure and initial plan of action.
Management strategies for fish populations in small impoundments are reviewed with consideration given to intensification techniques applied throughout the United States and Canada. The concept of balance in fish populations is used as a basis for illustrating the importance of maintaining desirable predator/prey relationships through stocking and harvest regulation of keystone predators. Generally, harvest levels for predators are reduced when species diversity and structural complexity of the environment are increased. Intensification is also achieved by enhancing water fertility through liming and fertilization. Case studies are presented representing contrasting climatic regions of North America while demonstrating similarities in management style. Principles and practices presented in this paper should be adaptable to the management of fisheries in small water bodies over a wider geographical range than discussed.
College football teams today play for tens of thousands of fans in palatial stadiums that rival those of pro teams. But most started out in humbler venues, from baseball parks to fairgrounds to cow pastures. This comprehensive guide traces the long and diverse history of playing grounds for more than 1000 varsity football schools, including bowl-eligible teams, as well as those in other divisions (FCS, D2, D3, NAIA).
The Conference on Aquaculture in the Third Millennium was held for the purpose of developing a strategy for aquaculture development in the next 20 years. It was a sequel to the Kyoto Conference on Aquaculture, which was organized by FAO in May-June 1976. This report of the Bangkok Conference on Aquaculture, the second publication arising from the Millennium Conference, includes the detailed recommendations of the 14 thematic conference sessions. The third publication will be the technical proceedings of the Bangkok Conference (available from NACA - see http: //www.enaca.org/).
