  • A new study has revealed significant ecological degradation in the Veli-Akkulam Lake, primarily driven by bio invasion.
  • The research employed the Eco path Model to assess the ecological efficiency and food web structure.
  • It revealed a decline in the Veli-Akkulam lake’s indigenous aquatic species and an increase in invasive species.
  • By the 2000s, the native species were replaced by the exotic and invasive Mozambique tilapia (Oreochromis mossambicus), which has now been overtaken by the Nile tilapia (Oreochromis niloticus).
