EQUIPMENT FOR WATER MACROINVERTEBRATE SUBSAMPLING

摘要

The present application aims at the performance of biomonitoring without requiring large sample volumes. Sampling in an aquatic environment is performed using an equipment comprising a tray provided with a tap and housing a perforated tray partitioned into 24 parts by a partitioning element. The equipment is positioned at the surface so as to allow the substrate to enter inside the tray, undesirable material is removed and excess water is drained before anesthetics are added and the contents are partitioned by the partitioning element. To end the process, the anesthetic solution is drained, and the substrates in the quadrats are collected and conditioned. The equipment may be optionally provided with legs.
