Q. What is Diadromous fish, recently seen in news?
Answer:
Fish that migrate between saltwater and freshwater environments
Notes: A study in the Journal of Applied Ecology found that Marine Protected Areas (MPAs) do not align with the core habitats of diadromous fish, which migrate between saltwater and freshwater. Examples include the allis shad and European eel. Diadromous fish are categorized as anadromous, catadromous, amphidromous, or potamodromous based on their migration patterns. These species face threats from human activities such as pollution, habitat destruction, and climate change.
