Freshwater quality

Small native fish eat a range of benthic invertebrates in streams. The larvae of mayflies and caddisflies are the most important food species, with chironomids being important for juvenile fish and in streams where all other prey are scarce.

A problem with recruitment is usually indicated by the absence, or very low density, of fish where they would normally be present.

Fish species thrive in a variety of different habitats.

Low recruitment could also be caused by widespread depletion of stocks

How may wind energy generation activities influence sediments in waterways?

What are the impacts of geothermal energy generation activities on water temperatures?

Generating electricity creates a lot of wasted energy in the form of heat, which then needs to be cooled before it can be discharged into the environment.
