這個獨特的生態系擁有世界唯一倖存的淡水珊瑚，超過1000種魚類，其中 700 種屬於當地特有種，豐富的鳥類生態，包含魚鷹、禿鷹、貓頭鷹與老鷹。
世界自然基金會(WWF)東非與南非區域計畫辦公室代表 Rubina Haroon 說，「保護尼亞薩湖對當地漁業有立即且持續的功效，提供了當地居民所需的食物也保障了他們的生計。」
The Mozambique government Friday declared Lake Niassa to be a reserve, safeguarding the species and natural habitats of one of the world's largest and the most biodiverse lakes.
Mozambique also Friday approved the protection of Lake Niassa under the Convention on Wetlands of International Importance, known as the Ramsar Convention. The Ramsar site includes the new reserve as well as the surrounding wetlands and watershed.
This unique ecosystem holds the world's only surviving freshwater corals; over 1,000 species of fish, 700 of which are endemic to the lake; and a wealth of bird life, including ospreys, palm nut vultures, owls and eagles.
The lake lies along flyways for birds that use the lake margins as staging areas as they migrate between Africa and Europe.
This southernmost lake in the Great Rift Valley system of East Africa is the eighth largest lake in the world and the second deepest lake in Africa. Vast plains extend to the south of the lake and steep sided mountains rise to the north. As it is about 52 miles wide and 365 miles long from north to south it is also known as The Calendar Lake.
The vast majority of the world's cichlid species are endemic to Lake Niassa and found nowhere else on Earth. New species are continually being discovered in the lake.
While Lake Niassa is facing threats from overexploitation, it supports the surrounding population, enabling fishing, agriculture, animal rearing, hunting, trade and handicrafts.
To reconcile the needs of the people with the need to protect natural resources, village level mechanisms for monitoring illegal and overfishing, erosion and deforestation, managing fisheries, and mitigating the impacts of climate change have been developed.
Local communities were instrumental in achieving success by making several concessions in order to protect their main source of food and income by agreeing to the closure of all fishing rivers during the annual spawning runs for lake salmon and other species, and the total protection of spawning beds during breeding season.
They created a team of community rangers responsible to district administration and cooperating with the Mozambique Navy to enforce existing laws surrounding illegal fishing, timber cutting, illegal migration, mining and piracy.
"Protecting Lake Niassa will have an immediate and lasting impact on the health of the fisheries located within it, providing security to the people who depend on the lake for their food and livelihoods," said Rubina Haroon, who represents WWF's Eastern and Southern Africa Regional Programme Office.
"Through an innovative approach to water use management, input from the local communities and the will of the government, we are able to protect endemic species of fish during the critical stages of their lifecycle," said Haroon.
The new reserve is the first freshwater lake under protection in Mozambique. It covers an area of 47,800 hectares adjoined by a buffer zone of another 89,300 hectares.
The reserve will be managed by the Ministry of Fisheries with support from the Ministry of Tourism and Ministry for Coordination of Environmental Affairs. Protection of this ecosystem enables plans to develop the tourism industry in northern Mozambique by appealing to travelers interested in diving, bird watching, game fishing and adventure trails.
