| The results of an initial research carried out in the several coastal aquifers are exposed. The studied areas are situated in the northern most part of Morocco. At the northeast are located the detrital aquifers of Smir and Martil-Alila, and in the northwest is located the detrital aquifer of Charf El Akab. The areas are underlain by detrital sediments of Pliocene to Quaternary age. Generally, groundwater has a high salinity and concentrations moder- ated to high of nitrates. The waters are meanly sodium-chloride type in Smir and Mart il- Alila aquifers. The waters are sodium-chlorid- and calcium-bicarbonate type in Charf El Akab aquifer. The hydrochemical study of the water of the aquifers shows that the salinity is conditioned by human activities (waste... |

| 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... |

| The farming of seaweed (Euchema spp.) began in the late 80’s, stimulated by government promotion and the active involvement of international corporations in promoting small-scale production. The industry grew rapidly in the early 90’s reaching 4,000 tonnes in 1995, but has since declined, related partly to marketing difficulties. There has been significant interest in shrimp farming for several years. Tanzania has good international trade routes, suitable climate, and a long coastline well suited to brackish-water pond production. To date the main interest has been in medium to large-scale projects with significant foreign interests. Environmental assessments have been carried out in respect of at least two proposed shrimp farm developments. The procedures... |
