Standards and codes of practice
Comply with the fish and fish habitat protection provisions of the Fisheries Act by incorporating measures to avoid:
- causing the death of fish
- harmful alteration, disruption or destruction of fish habitat in your work, undertaking or activity
If you can’t completely implement the measures to protect fish and fish habitat, check to see if a standard or code of practice applies 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 or 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 code of practices don’t apply or aren’t applicable to your work, undertaking or activity.
How to use the standard 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 this document to your work, undertaking or activity.
Section 3 outlines measures to follow for your work, undertaking or activity. Review the complete set of measures and only apply the measures that are applicable to your work, undertaking or activity.
Section 4 requests that you notify us when you use this 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.
Interim code of practice: end-of-pipe fish screens
View the interim end of pipe fish screens code of practice.
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.
- entrainment occurs when a fish is drawn into a water intake and cannot escape
- impingement occurs when a fish is held in contact with the intake screen and is unable to free itself
The end-of-pipe fish screen code of practice also provides:
- best practices for cleaning low volume water intakes that have the potential to impact fish
- guidance for using small-scale water intakes where the water intake flow rate is up to 0.150 cubic metres per second or 150 litres per second, including:
- municipal and private water supplies
- mining exploration
- information on the measures to follow to ensure maximum protection of fish
- fixed screen sizing and design specifications are exclusively for fish that have a minimum fork length of 25 mm
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 routine maintenance dredging code of practice.
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 waterbody. Dredging uses clam buckets, draglines or backhoes and suction.
Routine dredging helps to maintain the design depths of:
- navigation channels
- boat launches
- docking sites
- port facilities that contribute to:
- the transportation of goods
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:
- sedimentation of aquatic habitat
- alteration of aquatic habitat and vegetation
- change in riparian zones
- introduction of deleterious substances
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.
