| Summary: | Indigenous people are considered to be among the most vulnerable to food insecurity and biodiversity loss. Biodiversity is cited as a key component of indigenous food security; however, quantitative examples of this linkage are limited. We examined how species and population diversity influence the food security of indigenous fisheries for Pacific salmon (Oncorhynchus species). We compared two dimensions of food security – catch stability (interannual variability) and access (season length) – across a salmon diversity gradient for 21 fisheries on the Fraser River, Canada, over 30 years, using linear regression models. We used population diversity proxies derived from a range of existing measures because population-specific data were unavailable. While both population and species diversity were generally associated with higher catch stability and temporal access, population diversity had a stronger signal. Fisheries with access to high species diversity had up to 1·4 times more stable catch than predicted by ... : FraserFSCSalmonFisheries_CatchData_1983_2012This is a dataset of food, social, and ceremonial (FSC) fisheries weekly catch numbers of salmon on the Fraser River, BC, Canada from 1983 to 2012. FSC fisheries are indigenous fisheries that are jointly managed by Fisheries and Oceans Canada and indigenous groups. Data are available online (http://www.pac.dfo-mpo.gc.ca/fm-gp/fraser/archives-a-eng.html#First_Nations) and through request. Fisheries are managed by region. Column headers are: downstream_point (downstream point of each fishery management region), species (species of salmon caught), year, day (day number of year, represents beginning of week where fish were caught), weeklycatch (number of fish caught in that week), tributary (1 if the fishery was on a tributary, 0 if the fishery was on the mainstem of the Fraser), hells (0 if the fishery was downstream of Hell's Gate, 1 if the fishery was upstream of Hell's Gate), richness (population richness that the fishery had access to, see Nesbitt & Moore for ... |
