Autores: Francis, J.; Bryceson, I.
The coast of Tanzania is characterised by a wide diversity of biotopes and species, typical of the tropical Indowest Pacific oceans, and the peoples living there utilise a variety of its natural resources. Because of the extent of the diversity and variety, several different examples are used by this study to elucidate the complexity of issues and multiplicity of management responses related to use of coastal and marine resources. It emerges that coastal management requires an integrated cross-sectoral approach to address the wide array of interrelated issues involved.

This paper reviews the experience and status of coastal aquaculture of seaweeds, mollusks, fish and crustaceansin eastern Africa and the islands of the western Indian Ocean. In many respects, coastal aquaculture is still in itsinfancy in the region, and there is a pressing need toformulate development strategies aimed at improving theincome and assuring the availability of affordable protein tocoastal communities. This paper also draws from positive and negative experiences in other parts of the world. Therequirements of feed and fry, and the conversion ofmangroves are used to illustrate how some aquacultureactivities constitute a net loss to global seafood production.The paper presents both general and specific sustainability guidelines based on the...

Coastal Aquaculture Developments in Tanzania: Sustainable and Non-sustainable Experiences
Provedor de dados: 20
Autores: Bryceson, I.
Coastal aquaculture of seaweeds and prawns has developed in  Tanzania during the past two decades. Farming of Eucheuma seaweeds commenced in 1989 along the east coast of Zanzibar and it has since expanded to other areas. This form of aquaculture does not pollute the environment with feeds, wastes or other chemicals, although there are some negative interactions causing inhibition of surrounding biota, but which appear to be relatively mild. Monoculture may result in some self-inhibition and disease vulnerability over time. The socio-economic impacts of seaweed farming was initially overwhelmingly positive, providing income to women from relatively poor remote villages. Annual production reached 7000 tonnes constituting an important earning of foreign...

Autores: Bryceson, I.; Massinga, A.
Coastal resource utilization and management systems, bothtraditional and more recently conceived, were studied in Mecufidistrict, northern Mozambique in a post-conflict situation prior towhich a significant migration of people to the coast had occurred.A wide variety of coastal biotopes containing a multitude ofresources had been affected in various ways. Intertidalorganisms exhibited signs of decreasing abundance and averagesize, whereas offshore fishes and mangrove forests did not showsigns of overutilization. It was observed that traditional coastalmanagement systems were still influential, but that newerinitiatives were only beginning to enter into significant dialogueand cooperation with these. In the current circumstances ofpeace and political...
