On the freshwater ostracods (Crustacea, Ostracoda) of the Sudan, with special reference to the Red Sed; . (Masi, 1932) is placed in the synonymy of . (Lindroth, 1953) is recorded for the first time since its original description and is redescribed, while . Rome, 1969 is transferred to .. The zoogeographical composition of this fauna is briefly discussed.

Primary production and respiration of the phytoplankton in the Blue and White Niles at Khartoum0.41 gCm.d. (0.09 mgO.l.h.) in May to 3.74 gCm.d. (0.83 mgO.l.h.) in November. The maximum rates of respiration in the Blue Nile and White Nile were 0.10 and 0.63 mgO.l. h. respectively. The ratios net:gross production were generally higher in the White Nile than in the Blue Nile.

Effects of 2,4-D on mature and juvenile plants of water hyacinth (, (Mart.) Solms)o half the rate of 2,4-D normally used for control of water hyacinth in the Sudan. The lower rate of 2,4-D not only means a considerable reduction in quantity and cost of the consumed herbicide but also a substantial minimisation in the level at which pollution may build up in the White Nile of the Sudan.

Ecological observations on mangroves of the Red Sea shores of the Sudanaccessible locations; salt pans and to a limited extend cutting contribute in part to the process of degradation. The badly damaged aggregations may benefit from protection through control of grazing by nomadic camel tribesmen.

apparent while we were doing some joint field work in the Nile Valley and along the Red Sea coast. We feel that several reasons justify its publication. Firstly, a vast amount of information is being gathered year after year by the staff of the Hydrobiological Research U nit of the University of Kh

Observations on the effect of the weevils , Warner and , Hustache on the growth of water hyacinth hyacinth plants for a period of 61 days (one generation period) reduced their population growth by 25.4% and 12.7% respectively. The progeny of both species in a mixed culture reduced the growth of the plants by 22.5% in the same period, while in the control the population of the plants increased 136.6%.
