A state agency in Chennai is taking action to protect native fish species by culling invasive African-origin Tilapia in Adyar Creek. Tilapia, introduced in the 1950s, has spread rapidly across freshwater bodies in Tamil Nadu, threatening local fish populations. The introduction of Genetically Improved Farmed Tilapia worsened the situation, leading to a targeted culling operation by the Chennai River Restoration Trust. While this has led to an increase in native fish species, experts emphasize the need for a comprehensive policy to address invasive species and protect local ecosystems. Educating the public and conducting surveys of native fish species are crucial steps in finding a lasting solution.
