Abstract Pacific salmon ( Oncorhynchus spp.) are a foundation species around the north Pacific, yet many wild populations have experienced steep declines over last decades associated with decreased marine survival. Due to limited sampling, our understanding of dynamic North Ocean ecosystem remains poor and factors impacting survival remain largely unknown, specifically in winter when face resources. Here, we present late ecosystem‐wide environmental DNA (eDNA) survey performed 2019 2020 Gulf...
Molecular techniques are expected to be highly useful in detecting taxa causing harmful algal blooms (HABs). This is the first report Canada evaluating HABs-related species identification using a combination of morphological and molecular approaches. Microscopy, quantitative polymerase chain reaction (qPCR), metabarcoding with multiple markers (i.e., 16S, 18S-dinoflagellate 18S-diatom, large subunit (28S) rDNA) were applied on samples ( n = 54) containing suspected algae (e.g., Alexandrium...
In British Columbia (BC), harmful algal blooms (HABs) regularly cause severe economic losses through finfish mortalities and shellfish harvest closures due to toxin accumulation, gill damage, or hypoxia. As there is no routine governmental monitoring of HAB phenomena in BC, variability, its potential links environmental drivers are not well understood. Here we present results from a well-managed citizen science program which collected an unprecedented 4 year, high-resolution (∼bi-monthly,...
Salmon are keystone species across the North Pacific, supporting ecosystems, commercial opportunities, and cultural identity. Nevertheless, many wild salmon stocks have experienced significant declines. restoration efforts focus on fresh coastal waters, but little is known about open ocean environment. Here we use high throughput RT-qPCR tools to provide first report health, condition, infection profile of coho, chum, pink, sockeye in Gulf Alaska during 2019 winter. We found lower infectious...
Based on a four year study conducted in Cowichan Bay, Canada, potential linkages between composition and abundance of phytoplankton the feeding histopathology juvenile salmon were noted. During two dense blooms (Skeletonema spp. Pseudo-nitzschia spp.), Chinook decreased (n=202, empty stomachs >50%). All collected gills (n=5) damaged following high levels mechanically harmful Chaetoceros convolutus water column; all livers showed signs pathological changes during Octactis speculum bloom....

During almost 100 years of fishing, an average annual catch salmon in the Russian Far East (RFE) was about 170,000 tons, which, approximately 110,000 tons (data for 1971-2020) were contributed by Kamchatka stocks (Fig. 1).On average, RFE catches consisted 60-70% pink (Oncorhynchusgorbuscha), 25% chum (O.keta), and 10% sockeye (O.nerka) salmon.The other Pacific species together < 5% total.The share slightly lower (up to 15%), while higher (more than 15%).In recent decade (2011-2020),...
