Part of the Monographiae Biologicae book series (MOBI, volume 35) The importance of Lake Chilwa as a commercial fishery was first recognized by Hornby (). He ‘conservatively’ estimated that tonnes wet weight of fish were being cropped annually from Lake by: Leonard C.

Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life.

The next recorded account of the L. Chilwa fishes occurs in 'The report on the Tilapia and other fish and fisheries of Lake Nyasa' by R. Lowe (now Mrs.

McConnell) published in A few notes are included on the fish and fisheries of L. Chilwa, and the three commercially important species are listed (Barbus paludinosus, Clarias mossambicus and a new.

Lake Chilwa produces between zero metric tons of fish per year, making it one of the most productive but variable lakes in Africa. The size of the lake varies seasonally and among years.

The lake is a closed system with several inflowing rivers but no outlet. As such, water in the wetland is lost through evaporation, transpiration and seepage, and the remainder is what constitutes Lake Chilwa. Lake Chilwa is the second-largest lake in Malawi after Lake is in eastern Zomba District, near the border with imately 60 km long and 40 km wide, the lake is surrounded by extensive is a large island in the middle of the lake called Chisi lake has no outlet, and the level of water is greatly affected by seasonal rains and summer countries: Malawi.

By Mercy Phiri Lakes are critical to the people of Malawi, providing them with nutrition as well as a vital livelihood. So when local communities decided this winter to extend the closed season at Lake Chilwa, which is Malawi’s second largest lake and accounts for a quarter of all the country’s fish production, it was not a choice they made lightly.

Lake Chiuta is 3–4 meters deep and ranges in size from 25 to square kilometers. The Lake Chilwa basin is now under threat from low rainfall, invensive farming methods, siltation and effects of climate change.

With a history of drying up during acute drought spells, one only prays that conservation efforts from various players will be able to mitigate against the destructive forces bent on decimating this precious ecosystem.

1. INTRODUCTION. In between recessions [17], Lake Chilwa is one of the most productive freshwater lakes in Malawi with a fishery production of between 80 and kg/ha resulting in a long-term annual average catch of around 15 metric lake has an important bearing on the nutrition of Malawians, in particular within the nearby districts of Zomba, Phalombe and Machinga.Lake Chilwa produces between zero metric tons of fish per year, making it one of the most productive but variable lakes in Africa.

The size of the lake varies seasonally and among years, sometimes drying completely. Its surrounding wetland and floodplain provide habitat for a diversity of birds and economically valuable grasses and Cited by: lake’s fisheries resources began to suffer from the decline of the Lake Chilwa fish trade, a trend that continued well into when the fishery completely collapsed.

The decline in fish trade forced some traders to start exploring other fishing areas, such as the Upper Shire River at Liwonde, and Lake Malawi in Mangochi.
