Restoring fish food
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. -
Poor recruitment
A problem with recruitment is usually indicated by the absence, or very low density, of fish where they would normally be present. -
Restoring physical stream habitat
Fish species thrive in a variety of different habitats. -

Stocking fish
If the low abundance of fish in your stream is not related to a reduction in habitat, waterquality, flow or the presence of downstream barriers, it might be due to the inability of juvenile fish to enter the stream. -

Water temperature and thermal
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.
