    Description: Lake Manzalah; the largest delta Lake in Egypt represents a dynamic system that has been undergoing continuous and pronounced changes since long times. In the last year’s this Lake faced drastic problems that retarded its environmental and fisheries development; the most serious one is the discharge of waste water. It is attempted in the present study to investigate the chemical characters of Lake Manzalah water during 2001-2002. Water temperature ranged from an average of 12.35oC in January and 29.14oC in July. Dissolved Oxygen, pH and total dissolved solids were found in ranges optimum for the living of marine and freshwater fish species. The average concentrations of nutrients lied in the following ranges: 1.24 to 4.89 μmol PO4 -3 l-1 , 5.08 to 28.73 μmol SiO4 -2 l-1 and 1.81 to 17.7 μ_mol NO3-1 l-1 The concentrations of phosphorus and nitrogen compounds were found to be relatively higher at the southern regions of the Lake near to the outlets of the drains.

    Description: This synopsis describes the development of marine biological research, including fisheries, in Mozambique. With around 3000 km of coastline, the living resources of the sea playa major role in the Mozambican society, mainly as a source of protein and income for the population, and of foreign revenue through exports. In the first years, after independence, in 1975, research activities in marine sciences were limited and mainly concentrated to fisheries through cooperation with Norway and the Soviet Union. A new era for biology started in 1985 when the Faculty of Biology at Universidade Eduardo Mondlane was re-opened. A 5yr curriculum towards a licentiate degree was introduced with a strong marine profile. Since the 1990s, a very dynamic de-velopment in Mozambican marine biological research has occurred. Several academic degrees in marine biology from universities abroad were obtained, and local expertise developed; building vital institutions and enrolling in advanced research activities.
