Singapore's conversion of a 2.7-km concrete canal into a meandering river has boosted biodiversity by 30 per cent, a new study confirms. The Bishan-Ang Mo Kio Park waterway, part of the city-state's Active, Beautiful, Clean (ABC) Waters Programme, saw fish species richness rise significantly. Three native species were recorded in the rehabilitated stretch, while the untreated canal downstream had none. The 3-km river, completed in 2011, now hosts a more varied fish community, with non-native fish still dominant, reports Times of India. Researchers surveyed 8,325 fish across 26 species between 2016 and 2018. Quetzal cichlid made up 68 per cent of the catch and tilapia 17 per cent.
