Southwestern Sri Lanka rivers and streams

Southwestern Sri Lanka rivers and streams is a freshwater ecoregion in Sri Lanka. The ecoregion is listed in Global 200, a list of ecoregions compiled by the World Wide Fund for Nature for conservation priorities.[1] The extensive network of rivers and streams of Sri Lanka drains a total of 103 distinct natural river basins.[2] Several waterfall habitats have been formed as a result of rivers and streams flowing through high and mid elevation areas. The ecoregion spreads over 15,500 km2 in the wet zone of the southwestern part of Sri Lanka. More than a quarter of the freshwater fishes that have been discovered in Southwestern Sri Lanka rivers and streams are endemic.[3] Nine endemic genera of freshwater fishes of Western Ghats and Sri Lanka hotspot Malpulutta are found only in Sri Lanka.[4] Studies suggest that the number of species still to be discovered is quite high.[3] Until recently wetlands in Sri Lanka were used for drainage, construction sites and land fills.[5]

Aquarium
An aquarium (plural aquariums or aquaria) is a vivarium consisting of at least one transparent side in which water-dwelling plants or animals are kept. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, marine mammals, turtles, and aquatic plants. The term combines the Latin root aqua, meaning water, with the suffix -arium, meaning "a place for relating to".[1]
Butterflies of Sri Lanka
Sri Lanka is home to 245 species of butterflies with 23 of these being endemic to the island.[1] Of the 245 species, 76 are listed as threatened nationally, while Ceylon Rose is designated as critically endangered.[2]
Commercial fishing
Commercial fishing is the activity of capturing fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large scale commercial fishing is also known as industrial fishing.
