[2] Evaporation accounts for more than 80% of the water loss from the lake, considerably more than the outflowing Shire River. [10][51] The second main haplochromine group are the mbuna, a name used both locally and popularly, which means "rockfish" in Tonga. It is the 9th largest lake in the world and is located between Malawi, Mozambique and Tanzania. The permanent stratification of Lake Malawi's water and the oxic-anoxic boundary (relating to oxygen in the water) are maintained by moderately small chemical and thermal gradients. Ecological consequences of early Late Pleistocene megadroughts in tropical Africas. 1 The lakeshore people, particularly those in landlocked Malawi, rely on the lake for water, transport, recreation, electricity, irrigation, and most importantly, fish.

Lake Malawi is one of the African Great Lakes. Rhoades's crew found the Hermann von Wissmann in a bay near Sphinxhaven, in German East African territorial waters. Age of Lake Malawi (Nyasa) and water level fluctuations. [11] The oxygen limit is at a depth of approximately 250 m (820 ft), effectively restricting fish and other aerobic organisms to the upper part. The high seasonal norm is 86°F. Teugels (1999). Stauffer, J.R.; and H. Madsen (2012). [10] However, during the rainy season months of January to March, the waters are more muddy due to muddy river inflows. The haps (they were formerly included in Haplochromis) can be further subdivided into three subgroups: The relatively large, often more than 20 cm (8 in) long, and aggressive piscivores that roam various habitats in pursuit of prey, the open-water (although often not far from sand or rocks) utaka that feed in schools on zooplankton and typically are of medium size, and finally a subgroup of "aberrant" species that essentially are defined by them not fitting clearly into the other subgroups. A trophic model of Lake Malawi. Schistosomiasis. ). [68], Lake Malawi is home to 28 species of freshwater snails (including 16 endemics) and 9 bivalves (2 endemics, Aspatharia subreniformis and the unionid Nyassunio nyassaensis). [25] The Lake of Stars nickname came after Livingstone observed lights from the lanterns of the fishermen in Malawi on their boats, that resemble, from a distance, stars in the sky.

[27][28], The partition of the lake's surface area between Malawi and Tanzania is under dispute. This change, first noticed in the mid-1980s, is possibly related to a decline in snail-eating cichlids (for example, Trematocranus placodon) due to overfishing and/or a new strain of the bilharzia parasite. The average water temperature in Lake Malawi in winter reaches 28°C/82.4°F, in spring 28°C/82.4°F, in summer the average temperature rises to 25°C/77°F, and in autumn it is 26°C/78.8°F.

Schistosomiasis in Lake Malawi and the Potential Use of Indigenous Fish for Biological Control. 4. Sustainable water resources development of Malawi needs a thorough assessment of the impact of climate change on the future water levels of Lake Malawi because Lake Malawi together with its outflowing Shire river water system is Malawi’s most important water resource for hydropower generation, water supply for industrial and domestic use in the city of Blantyre and its surrounding … Water temperature forecasts for the long term tend to be misleading. Malawi kent een regenseizoen dat loopt van november tot en met april. [21], Unlike Lake Tanganyika with its many endemic freshwater crabs and shrimp, there are few such species in Lake Malawi. [10][58][66] Male chambo have unique genital tassels when breeding, which aid in egg fertilisation in a manner comparable to the egg-spots on the anal fin of haplochromines. Martens, K. (2003). [19] During the peak of the low-water period between 1390 and 1860 AD, it may have been 120–150 m (390–490 ft) below current water levels.

[75] Pelagic zooplanktonic species include two cladocerans (Diaphanosoma excisum and Bosmina longirostris), three copepods (Tropodiaptomus cunningtoni, Thermocyclops neglectus and Mesocyclops aequatorialis),[76] and several ostracods (including both described and undescribed species). The Nonendemic Haplochromine Cichlids of Lake Malawi. van Huis, A.; H. van Gurp; and M. Dicke (2012). The thermocline is located at a depth of 40–100 m (130–330 ft). Smaller tanks can go with a single heater, whereas larger tanks should use two. [78][81] They lay their eggs at the water's surface and the adults die. The climate in may in Malawi lake is rather dry ; it hardly ever rains (0.8in of rainfall over 5 days). Delvaux, D. (1995).

The lake's water is alkaline (pH 7.7–8.6) and warm with a typical surface temperature between 24 and 29 °C (75–84 °F), while deep sections typically are about 22 °C (72 °F). [49], 1. [7][10] Except for four species (Astatotilapia calliptera, Coptodon rendalli, Oreochromis shiranus and Serranochromis robustus), all cichlids in the lake are endemic to the Malawi system, which also includes nearby smaller Lake Malombe and the upper Shire River. Water temperature should be 23-28 o C (73-82 o F), so a middle value of 25-26 o C (77-79 o F) is probably ideal. The water has a hardness level of GH 7 and KH 10-12. All species from Lake Malawi thrive in the temperature range of 77-84 °F. [18][20] A water chemistry resembling the current conditions only appeared about 60,000 years ago. [10] Another smaller depression in the far north reaches a depth of 528 m (1,732 ft). [18][19], The water levels have varied dramatically over time, ranging from almost 600 m (2,000 ft) below current level[20] to 10–20 m (33–66 ft) above. There are boats and boards of all types available to have fun with and to explore the waters, islands and beaches of the lake.
