Chinook salmon exhibit long-term rearing and early marine growth in the Fraser River, B.C., a large urban estuary

Chinook salmon exhibit long-term rearing and early marine growth in the Fraser River, B.C., a large urban estuary

Using tiny salmon ear bones, or otoliths, Raincoast researchers and partners were able to demonstrate that Chinook salmon from Harrison River rely on the Fraser estuary for one to two months while they feed and grow. These findings underscore the critical nature of this habitat for the persistence and recovery of Chinook salmon…

Research: Conservation in heavily urbanized biodiverse regions requires urgent management action and attention to governance

Research: Conservation in heavily urbanized biodiverse regions requires urgent management action and attention to governance

A new open access research paper led by Dr. Tara Martin at the UBC Conservation Decisions Lab applied a novel conservation decision making tool called Priority Threat Management to identify the most cost-effective management strategies needed to address the threats facing 102 species at risk identified in the area…

Habitat use by juvenile salmon, other migratory fish, and resident fish species underscores the importance of estuarine habitat mosaics

Habitat use by juvenile salmon, other migratory fish, and resident fish species underscores the importance of estuarine habitat mosaics

Pacific salmon, especially Chinook and Chum, reside and feed in estuaries during downstream migrations. But the extent to which they rely on estuaries, and which habitats within estuaries, is not well understood. We need to understand this complexity if we are going to enact effective conservation policies. This is especially important in urban systems where habitat loss is ongoing, and at different rates across the estuarine mosaic. The Fraser River estuary, for example, supports a multitude of fish species…

Salmon species diversity predicts salmon consumption by terrestrial wildlife

Salmon species diversity predicts salmon consumption by terrestrial wildlife

Research by scientists at Spirit Bear Research Foundation, Raincoast Conservation Foundation, and the University of Victoria, led by Christina Service, shows that salmon species diversity – the number of spawning salmon species available – is far more important and positively related to salmon consumption in coastal black bears than biomass abundance…

Criteria for a good catch: A conceptual framework to guide sourcing of sustainable salmon fisheries

Criteria for a good catch: A conceptual framework to guide sourcing of sustainable salmon fisheries

The proposed new framework for identifying sustainably harvested salmon suggests that individual retailers develop criteria (or adopt others) that comply with this place-based foundation. Patagonia Provisions is one retailer requesting this high standard of certification because their customers want higher standards than are currently available…
