Salmonid enhancement program aquaculture licence - Appendix VII - In-stream placement of salmon carcasses for nutrient enrichment

This webpage is intended for informational purposes only.

The Salmonid Enhancement Program undertakes in-stream placement of spawned salmon carcasses to provide watersheds with nutrients and organic matter derived from the ocean. Salmon carcasses play a key role in maintaining productivity of salmonid systems, benefiting aquatic and terrestrial ecosystems. Rearing juveniles consume salmon eggs, feed directly on spawned-out carcasses, and benefit from increased abundance of invertebrates and algal growth. The presence of carcasses in streams has been related to increased juvenile density, growth rate, body size, improved fish condition, improved overwintering survival and increased marine survival. Riparian vegetation also benefits from nutrients derived from decaying carcasses transported into terrestrial ecosystems by bears and other animals.

Carcass placement programs adhere to the procedures detailed in the SEP Guidelines for in-Stream Placement of Salmon Carcasses for Nutrient Enrichment. Projects that meet the terms of the carcass placement guidelines will be issued an authorization letter from the Department allowing transport for deposition of carcasses. This letter accompanies all carcass movements.

Carcass placement plan

The Carcass Placement Plan requires the following information:

Carcass placement records and Post-carcass Placement records are maintained for each carcass placement project and contain the following information:

Carcass placement records

A Carcass Placement Record is kept for each carcass placement project and contains the following information:

Post carcass placement records

Monitoring of carcass placement locations is conducted two to four weeks after carcass placement and the following information is recorded for each project:

Planning and record forms and associated instructions for entering information are found in the SEP Guidelines for In-Stream Placement of Salmon Carcasses for Nutrient Enrichment.
