Fish Habitat Compensation

Fish habitat compensation (offsets) can provide a means to enable development related activities and development projects to proceed, while hopefully ensuring that the capacity of fish habitats to produce fish suitable for human consumption is maintained.

Users of FishHabitatNexus.com are asked to submit examples of fish habitat compensation measures to the website to facilitate continual improvement across the discipline.

In Canada, under the DFO Policy for the Management of Fish Habitat (Habitat Policy), each time the "harmful alteration, disruption or destruction" (HADD) of fish habitat is Authorized under the federal Fisheries Act, there is a requirement for compensation to replace the capacity of the lost habitat to produce fish. DFO has developed a Practitioner's Guide to Habitat Compensation to help habitat management practitioners when habitat compensation is required to meet the No Net Loss Principle of the DFO Habitat Policy.

In the U.S., similar provisions exist with respect to species at risk and Essential Fish Habitat (EFH).

In Canada, examples of fish habitat compensation include:

- Lower Cheakamus River Habitat Compensation, B.C.
