Context: CSIR-Centre for Cellular and Molecular Biology (CCMB) scientists discovered that the armoured sailfin catfish has infiltrated 60% of Eastern Ghats water bodies, causing damage to fishing nets and the ecosystem.
Abut Armoured sailfin catfish (ASC), also known as Rakashi or devil fish:
It was initially brought to India for its distinctive appearance and algae-cleaning abilities but has since multiplied significantly. Native to South America, it belongs to the largest catfish family.
Scientists employed the Environmental DNA (eDNA) approach to track the invasive species’ spread. eDNA refers to organismal DNA released into the environment via cellular material shed by organisms. This method, unlike conventional approaches, is reliable, accurate, and cost-effective. Invasive species, as defined by the Wildlife Protection Act, 1972 (amended in 2022), pose a threat to wildlife and their habitats.
