What happens to the macroinvertebrates collected during monitoring?

When macroinvertebrates are collected during monitoring, it is important to ensure that they remain alive for as long as possible to provide an accurate assessment of the aquatic ecosystem. Returning them to the water after counting allows researchers to minimize the impact of monitoring on the local population of these organisms. This practice not only contributes to maintaining the balance of the ecosystem but also demonstrates a commitment to conservation ethics.

The process involves carefully counting and documenting the macroinvertebrates, which provides essential data on water quality and ecosystem health. By returning them to their natural habitat, researchers facilitate the continued presence of these organisms, which play vital roles in the food web and environmental indicators. This approach is aligned with best practices in wildlife monitoring and study, aiming to gather valuable information while respecting and preserving the species involved.
