A Coast in Common: An Introduction to the Eastern African Action Plan OceanDocs
The coastline of Eastern Africa is an area of great physical beauty, rich in living resources. Palm fringed beaches of white coral sand lead down to tranquil lagoons enclosed by spectacular coral reefs with their wealth of colourful fish, shells and corals. The area has vast mangrove forests, high coral cliffs, wide stretches of sand dunes, and numerous offshore and oceanic islands. Yet there are problems in paradise-pollution, habitat destruction, and the pressures of growing populations and tourism. To face these common threats to their marine environment, the nine nations of the region are now working together to manage their shared resources and to find regional solutions to their problems. They are doing this under the auspices of the Eastern African...

Characterizing and Comparing the Spawning Habitats of Sardine (Sardinops sagax) and Anchovy (Engraulis encrasicolus) in the Northern Benguela Region OceanDocs
Tjizoo,Mbeurora Beau.
Spawning habitats of sardine and anchovy in eastern boundary current systems are characterized in an attempt to understand the fluctuations observed in their abundance. The northern Benguela, as an eastern boundary current system, is characterized by turbulent conditions that seem to govern the variability observed in the abundance of these species. Sardine and anchovy have developed mechanisms that enable them to maximize productivity. In the northern Benguela, spawning intensity is historically known to be high in periods and vicinities where turbulence is reduced. However, it is believed that selection of conditions for spawning by these species may change withfluctuations in abundance of fish.
