What are some methods to preserving aquatic biodiversity in Canada?

Answer 1

First thing would be to monitor the river so you know what is there. After you have done that protect the riparian area. Construction, mining, or livestock to close to the river or stream have be very harmful for the aquatic life. Lastly don't introduce non-native species. In many rivers the native life has been wipe out by the introduction of carp and brown trout.
