Discovery Passage Plankton Monitoring Program
The project involved the sampling of zooplankton, chlorophyll, and juvenile Coho to analyse the availability of food in the early marine environment. After 5 years, the pilot project came to an end and data showed that the late April released Coho did not survive as well as the mid and late May release Coho. Part of this was due to poor food availability for the juveniles at that time. Monitoring the zooplankton blooms has continued since then thanks to local support for the Monitoring Program, particularly support from the Campbell River Salmon Foundation.
Stewardship groups and various hatcheries now use the data produced to see what the productivity is like at the time of release of their Coho as well as other juvenile salmonids. It allows one more piece of the puzzle to be taken into account when their fish are released.
