Assessment of Chinook Salmon residency in the Discovery Island area and measurement of acoustic target strength of wild juvenile salmon to inform their migration dynamics and interactions with aquaculture facilities
This project will assess the migration of juvenile wild salmon and potential interactions of wild and farmed fish in the Discovery Islands area using acoustic (sound-based) images from sonar and echosounders. We will analyze existing and new acoustic data to determine whether Chinook Salmon are resident in the area.
- To extend acoustic monitoring of wild juvenile salmon in Okisollo Channel (Discovery Islands) close to aquaculture facilities.
- To combine acoustic measurements from single-beam inverted echosounders and DIDSON imaging sonar with those from new split-beam echosounders. This would enable us to use previous and current acoustic measurements of juvenile salmon migration to estimate various parameters, including fish number and biomass.
