Biological Monitoring
Biological monitoring can reveal important changes in the composition of biological communities caused by human activities .The approach relies on the great diversity of benthic macroinvertebrate life in rivers and streams to determine how suitable a waterbody is for the support of aquatic life .
We get nets, a small aquarium to put the organisms and a sifter to catch small organisms .
En. Azli is showing the procedure how to do the Biological Monitoring
Catching the organisms that we have found
We are identifying the organisms that we have found using the biomonitoring cards
Species that we have caught .
Nymphs - swimming mayfly nymphs , damselfly nymphs and dragonfly nymphs
Larvae - beetle larvae and other fly larvae
Insects - other water bugs
Molluscs - pagoda snails and other snails
