Salmon Escapement (Coho, Chum, Chinook, Sockeye)
Definition:
Escapement is the number of salmon that “escape” fisheries (i.e., are not harvested) and return to fresh water to spawn.
Measurement and Limitations:
Salmon populations in the CVRD may be assessed by two monitoring methods, which tell us either true abundance (“true counts”) or relative abundance (“estimated counts”). The data presented here are all relative abundance of species encountered, which include coho, chinook, pink, sockeye and chum.
Pink salmon return to spawn every second year and are presented separately in Salmon Escapement (Pinks). Data present the average based on estimates in 2017, 2019, and 2021.
Data geography is Comox Area (14) includes the following streams: Puntledge River, Oyster River, Rosewall Creek, Roy Creek, and Tsolum River.
For total results of all species for all streams and detail on Escapement Monitoring Methods, please refer to the 2021 Strait of Georgia Escapement Bulletin [PDF] or visit Fisheries and Oceans Canada (dfo-mpo.gc.ca).

14. Conserve and sustainably use the oceans, seas and marine resources
The world’s oceans – their temperature, chemistry, currents and life – drive global systems that make the Earth habitable for humankind.
Our rainwater, drinking water, weather, climate, coastlines, much of our food, and even the oxygen in the air we breathe, are all ultimately provided and regulated by the sea. Throughout history, oceans and seas have been vital conduits for trade and transportation.
Careful management of this essential global resource is a key feature of a sustainable future.
