How do water louse show pollution?

Answer 1

Water louse, or Asellus aquaticus, can serve as bioindicators of water quality and pollution. Their presence, abundance, and health can reflect the levels of organic pollution in aquatic environments, as they are sensitive to changes in water chemistry. High concentrations of water louse may indicate a moderate level of pollution, while their decline suggests deteriorating water quality or habitat degradation. Monitoring their populations helps assess ecosystem health and the impact of pollutants.
