Lake Malawi is one of the three rift lakes of Eastern Africa, along with Lake Tanganyika and Lake Victoria, and stretches 360 miles from north to south. As typical of utaka, Copadichromis azureus has bright blue males (shown) and duller females that are silvery with dark spots. [10][50][51] The best time and weather to travel to Malawi 2020. Metal heaters are recommended [10] Another smaller depression in the far north reaches a depth of 528 m (1,732 ft). Ecological Modelling 221: 713–727. Recent research in the African Great Lakes: Fisheries, biodiversity and cichlid evolution. Gwendolen disabled the German boat with a single cannon shot from a range of about 1,800 metres (2,000 yd). Diplotaxodon, one of the very few cichlid genera that occurs offshore in relatively deep water. Lake Malawi has two inhabited islands: Likoma Island [photo below] and Chizumulu Island. Lake Malawi is home to the greatest number of fish species among all the lakes on Earth, including 1,000 species of cichlids.Lake Malawi is shared by 3 countries: Malawi, Mozambique, and Tanzania. ). [23], The Portuguese trader Candido José da Costa Cardoso was the first European to visit the lake in 1846. This is called a divergent plate tectonics boundary. A survey in Monkey Bay in 1964 found two endemic species of snails of the genus (B. nyassanus and B. succinoides) in the lake, and two non-endemic species (B. globosus and B. forskalli) in lagoons separated from it. Note that these seasonal averages are in contrast with those observed in Malawi lake in the month of april with a maximum record of 92°F in 2014 and a minimum record of 67°F in 2009. [37] She normally serves the southern part of the lake but if Ilala was out of service she operated the route to Karonga. [18][20] A water chemistry resembling the current conditions only appeared about 60,000 years ago. Smaller tanks can go with a single heater, whereas larger tanks should use two. ; and A.S. Cohen (2011). At the lower end of this scale, the fish may be less aggressive, but also less active and less inclined to breed. It was revealed that approximately 50 litres of non radioactive material leaked into a local creek. [55], Lake Malawi is noted for being the site of evolutionary radiations among several groups of animals, most notably cichlid fish. [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. Current estimates indicate that more than 1,000 species of tropical fish are present in the lake, including 350 fish that are unique to this ecosystem. the weather in Malawi lake in october is quite dry ; it hardly ever rains (0.7in of precipitation over 4 days). [78][81] They lay their eggs at the water's surface and the adults die. Segers, H.; and Martens, K; editors (2005).

Ruaha (a currently undescribed species from Great Ruaha River), and these two separated between 2.13 and 6.76 million years ago (mya). Palaeogeography, Palaeoclimatology, Palaeoecology 303: 71–80. [10], At a genus level, most of these are widespread in Africa, but Bathyclarias is entirely restricted to the lake. The lake’s middle line and its northern and eastern shores form much of Malawi’s boundary with Tanzania and Mozambique. [43][44] A drop in the lake's water level represents another threat, and is believed to be driven by water extraction by the increasing human population, climate change and deforestation. It is the 9th largest lake in the world and is located between Malawi, Mozambique and Tanzania. "Rapid drop in Lake Malawi's water levels drives down fish stocks", 10.2305/IUCN.UK.2018-2.RLTS.T60856A155041757.en, 10.2305/IUCN.UK.2018-2.RLTS.T61293A148647939.en, 10.2305/IUCN.UK.2018-2.RLTS.T60760A148648312.en, "Rangers struggle to save endangered fish in Lake Malawi".

[33] In 2012, Malawi's oil exploration initiative brought the issue to the fore, with Tanzania demanding that exploration cease until the dispute was settled. Here you will find the 14 day weather forecast for Lake Malawi. 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. A Fishkeepers Guide to African Cichlids, p. 97. 3. [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. Water temperatures are calculated based on the data over the past 10 years. Pp. In recent years she has often been out of service, but when operational she runs between Monkey Bay at the southern end of the lake to Karonga on the northern end, and occasionally to the Iringa Region of Tanzania. Note that these seasonal averages are in contrast with those observed in Malawi lake in july with a maximum record of 90°F in 2015 and a minimum record of 59°F in 2009. She later served as a ferry and is currently being renovated into a mobile clinic at Monkey Bay. [10] The southern half of the lake is shallower; less than 400 m (1,300 ft) in the south-central part and less than 200 m (660 ft) in the far south. [48] The IUCN recognises 117 species of Malawi cichlids as threatened; some of these have tiny ranges and may be restricted to rocky coastlines only a few hundred metres long. There are boats and boards of all types available to have fun with and to explore the waters, islands and beaches of the lake. Geographical ancestry of Lake Malawi’s cichlid fish diversity. Ecological consequences of early Late Pleistocene megadroughts in tropical Africas.

The average water temperature in Lake Malawi in winter reaches 82.4°F/28°C, in spring 82.4°F/28°C, in summer the average temperature rises to 77°F/25°C, and in autumn it is 78.8°F/26°C. pH 7.5-8.4 is ideal with an almost pristine (near 0 ppm) ammonia and ammonium nitrite content. About 83% of the lake’s annual water loss comes through evaporation, leaving the lake sensitive to outside influences such as rainfall, as it does not have a strong buffer of rivers and streams. [36] The ferry MV Ilala entered service in 1951. In addition to the table values, the graph below displays of changes average surface water temperature during the year. Water temperature in Lake Malawi today is 83.8°F/28.8°C. Givnish, T.J.; and K.J. Diets and food consumption rates of pelagic fish in Lake Malawi, Africa.

"Seasonal and Interannual Particle Export in an African Rift Valley Lake: A 5-Yr Record from Lake Malawi, Southern East Africa". Temperature and dissolved oxygen concentration of the water column generally decrease with depth from over 28° C and over 80% saturation at the surface to just below 22.7° C and anoxic conditions … Fossorochromis rostratus is an "aberrant" hap that often sifts mouthfuls of sand to extract small food organisms. Among the most popular are the four species of chambo, consisting of any one of four species in the subgenus Nyasalapia (Oreochromis karongae, O. lidole, O. saka and O. squamipinnis), as well as the closely related O. [12] Concerns have been raised over the future climate change impacts of Lake Malawi due to the recent decline in lake levels and the overall drying trend. [10][51][62] Adult male haps generally display bright colors, while juveniles of both sexes and adult females typically show a silvery or grey coloration with sometimes irregular black bars or other markings.
