THE LEADING NETWORK OF LABORATORIES SPECIALISING IN BENTHIC MACROINVERTEBRATES

Identification and counting of benthic macroinvertebrates

Benthic macroinvertebrates are relatively large invertebrate organisms (generally larger than 0.5 mm) that live on the bottom of aquatic ecosystems, both in inland waters (rivers, lakes, wetlands and reservoirs) and in marine and coastal waters.

This group includes a wide variety of taxa, notably aquatic insects (mayflies, stoneflies, caddisflies, flies, beetles and dragonflies), molluscs (gastropods and bivalves), annelids (oligochaetes, hirudinea and polychaetes), crustaceans (amphipods, isopods and decapods), as well as other benthic invertebrates such as flatworms, nematodes and sponges.

Due to their sensitivity to environmental changes, benthic macroinvertebrates are widely used as bioindicators of water quality and the ecological status of aquatic ecosystems.


Types of benthic macroinvertebrates we analysed


Benthic macroinvertebrates in continental aquatic ecosystems: rivers, lakes, wetlands and reservoirs


Marine, coastal and transitional water benthic macroinvertebrates: submerged areas, intertidal zones, coastal lagoons and salt marshes

Why are benthic macroinvertebrates analysed?

Impact detection and indicator species

It enables the identification of species that are sensitive to or tolerant of pollution, as well as the detection of environmental impacts caused by discharges, dredging or habitat alterations.

Assessment of ecological status

It analyses the composition and abundance of benthic communities to determine the quality of the ecosystem, taking into account both current conditions and the cumulative effects over time.

Environmental monitoring and regulatory compliance

It serves as a basis for the development of environmental monitoring programmes and for ensuring compliance with current legislation on environmental impact assessments, discharge controls and water body management.

Support for management and decision-making

It provides key information for the planning, restoration and sustainable management of the aquatic environment, facilitating the adoption of corrective and preventative measures.
