Скачать или смотреть The Invasive fishes of India | Tamil

Invasive species often outcompete native species for food, breeding grounds, and shelter due to traits like aggressive feeding, rapid growth, and high reproduction. Species like carp and goldfish uproot aquatic vegetation and stir sediment during feeding, causing murkier waters, loss of macrophytes, and degraded habitat structure. Invasive fish can introduce harmful parasites to native species. Invasive species alter water quality (e.g, increased turbidity, nitrogen, organic matter) and contribute to eutrophication. These organisms can function as ecosystem engineers, affecting nutrient cycling, food webs, and ecosystem productivity.
