Standards and codes of practice

Comply with the fish and fish habitat protection provisions of the Fisheries Act by incorporating measures to avoid:

If you can’t completely implement the measures to protect fish and fish habitat, check to see if standards and codes of practice apply to your project.

A code of practice specifies procedures, practices or standards for avoiding the death of fish or the harmful alteration, disruption or destruction of fish habitat. This is in relation to works, undertakings and activities during various phases of their life cycle, such as construction, operation, maintenance or decommissioning.

You may need to request a project review if these standards and codes of practice don’t apply or aren’t applicable to your works, undertakings and activities.

How to use the standards and codes of practice

Section 1 describes the works, undertakings and activities addressed by the code of practice and the potential impacts on fish and fish habitat which the best practices may alleviate.

Section 2 helps you determine if you can apply the code of practice to your works, undertakings and activities.

Section 3 outlines measures to follow for your works, undertakings and activities. Review the complete set of measures and only apply the measures that are applicable to your works, undertakings and activities.

Section 4 requests that you notify us when you use the code of practice.

Section 5 provides contact information in case you have further questions.

Section 6 provides a glossary to ensure that key terms are understood.

The culvert maintenance code of practice provides useful information on the measures to follow to ensure that fish and fish habitat are protected. Potential impacts to fish habitat from culvert maintenance include:

Interim code of practice: end-of-pipe fish protection screens for small water intakes in freshwater

View the interim code of practice for end-of-pipe fish screens for small water intakes in freshwater.

This interim code of practice provides guidance on the design, installation and maintenance of small end-of-pipe water intake fish screens to prevent entrainment and impingement of fish.

The end-of-pipe fish screen code of practice also provides:

This code of practice does not cover impacts related to fish habitat and changes in flow conditions.

Interim code of practice: routine maintenance dredging

View the interim code of practice for routine maintenance dredging.

This interim code of practice provides best practices for routine maintenance dredging, which occurs at least once every 10 years.

Routine maintenance dredging involves the mechanical removal of accumulated sediment from the bed of a water body. Dredging uses clam buckets, draglines or backhoes and suction.

Routine dredging helps to maintain the design depths of:

The routine maintenance dredging code of practice provides useful information on the measures to follow to ensure that fish and fish habitat are protected. Potential impacts to fish habitat from routine maintenance dredging include:

This code applies to routine maintenance dredging only and does not apply to new dredging projects or to the expansion of a previously dredged area.

Interim code of practice: temporary stream crossings

View the interim code of practice for temporary stream crossings.

This interim code of practice provides best practices for temporary stream crossings. This includes fords, temporary clear span bridges (e.g., Bailey bridges, log stringer bridges) and winter crossings such as ice bridges and snow fills.
