Mitigation Techniques

The Habitat Management Program has prepared Fact Sheets that describe the effects of certain activities on fish and fish habitats in Newfoundland and Labrador. These fact sheets also describe techniques which can be implemented to prevent or minimize negative effects on fish and fish habitat.

It is important to note that using the information and adopting the techniques described in these documents does not necessarily mean an activity undertaken in an area containing fish habitat will receive DFO or other regulatory approval. Contact your local area habitat biologist to discuss your specific project or undertaking.
