Rivers and lakes of Djibouti


GEOGRAPHY AND CLIMATE
Djibouti, with a surface area of 21 980 km2, consists largely of volcanic plateau and desert. The climate is hot and dry. Djibouti is an important shipping port. There is some agriculture (coffee, livestock) but the soil is generally arid and unproductive.
2. HYDROLOGY
2.1 Lakes
There are two medium-sized lakes: Asal and Abbe.
2.2 Rivers, Floodplains and Swamps
None. Discharge to Lake Abbe is from Ethiopia and to Lake Asal from small mountain streams and gullies.
2.3 Reservoirs
None.
2.4 Coastal Lagoons
There is one medium-sized lagoon: Ghoubet Kharab.
2.5 Aquaculture
There is no aquaculture in Djibouti (Vincke, 1989, pers.comm.).
3. FISHERY PRODUCTION/POTENTIAL
3.1 Fish production and per caput supply (see Table 1, p.30)
3.2 Inland catch range and potential yield
No data available for Lakes Abbe and Asal, and Ghoubet Kharab Lagoon.
4. STATE OF THE FISHERY
4.1 Yield
Although no information is available, it may be assumed that a fishery exists at least on Ghoubet Kharab Lagoon. That catch, if any, could have been included in the marine production data.
4.2 Factors influencing yield
No significant freshwater waterbody. Active marine fishery.
4.3 Future development possibilities
No inland fishery development can be expected in Djibouti except, possibly, from the Ghoubet Kharab Lagoon.
