Riffles water
Riffles are biologically very important, because many aquatic species rely on them in one way or another. Many benthic macroinvertebrates are present in riffles, so fish often locate just downstream of a riffle to wait for these small creatures to drift down to them. That draws fisherman to these natural fish feeding stations as well. Riffles also serve to aerate the water, increasing the a… WebDec 6, 2024 · Water mites are one of the many groups of benthic arthropods and belong to several families.
