The Chalakudy River, also known as Chalakudy Puzha, is the fifth longest river in Kerala, India, flowing for 145.5 kilometers through the Thrissur, Palakkad, and Ernakulam districts .
The Chalakudy River is known for its rich biodiversity, particularly its fish population. The river is home to 98 species of freshwater fish, 35 of which are endemic to the Western Ghats. Sadly, due to overfishing, pollution, dams, and introduced species, 31 of these fish species are classified as vulnerable, endangered, or critically endangered. The National Bureau of Fish Genetic Resources has indicated that the Chalakudy River could be the richest river in terms of fish diversity in all of India .
The lush, evergreen riparian vegetation that lines the banks of the Chalakudy River provides habitat for many other species of plants and animals. Visitors can enjoy the scenic beauty of the river by taking a boat ride, going for a swim, or simply relaxing on the banks and taking in the views. The river is also a popular spot for fishing, although it's important to be aware of the conservation status of the fish species before casting a line.
