Inventories of aquatic species (fish, benthic macro invertebrates)

Benthic macroinvertebrates are visible to the naked eye.

Their main prey are bottom-dwelling invertebrates, primarily bivalve molluscs.

The Department is assessing benthic invertebrate monitoring for the purpose of assessing water quality.

Her expertise also include surveying benthic macroinvertebrates to assess water quality.

The young nourish of phytoplankton and of benthonic algae, the adults mainly of zooplankton, but also of small benthonic invertebrates, vegetables and debris.

Diet: Various kinds of fish, especially bottom-feeding fish, also crustaceans and other benthic animals.

In some instances, the benthic invertebrates themselves can influence water quality.
