Macroinvertebrate
Analysis
At Terra Pura, we offer a complete macroinvertebrate collection, processing, identification, and reporting service for environmental monitoring.
What are macroinvertebrates and why are they important?
Macroinvertebrates are small aquatic animals without backbones, such as insect larvae, worms, snails, and crustaceans. They are found in freshwater ecosystems like rivers and streams and are excellent biological indicators of water quality. Some species are very sensitive to pollution, while others can tolerate poor water conditions. By looking at which species are present and in what numbers, we can assess the health of a stream or river.
