Zebra Mussel (Dreissena polymorpha) and Quagga Mussel (Dreissena rostriformis bugensis) have a long history of invasion in European and North American freshwater ecosystems, with significant ecological and economic impacts. An ecological risk assessment for these two invasive species for...

The St. Anns Bank Marine Protected Area was established in June 2017. Data describing the spatial-temporal patterns and drivers of species movement is essential for evaluating species composition and to gauge the protective capacity of the MPA. Since 2015, an acoustic telemetry receiver array has...

Fisheries and Oceans Canada’s (DFO) National Biofouling Monitoring Program (BMP) has conducted annual field surveys to monitor the introduction, establishment, spread, species richness, and relative abundance of native and non-indigenous species (NIS) since 2006. Standardized monitoring protocols...

ABSTRACT In the coming decades, warming and deoxygenation of marine waters are anticipated to result in shifts in the distribution and abundance of fishes, with consequences for the diversity and composition of fish communities. Here, we combine fisheries-independent trawl survey data spanning...

In summer 2019, beach seining and paired environmental DNA (eDNA) sampling was conducted at ten sampling sites in coastal Nova Scotia, ranging from the Lunenburg area to the province’s Eastern Shore. A 25-metre Danish bag seine was deployed by boat twice at each site to capture fish and...

This report outlines the results of a project that created a series of maps tracking inshore historical Lobster fishing district boundaries from 1899 to present. This work has been part of Fisheries and Oceans Canada’s (DFO) Blue Economy Lobster Team (BELT) pilot project on the Lobster fishery....

Species distribution models (SDMs) are tools that combine species observations of occurrence, abundance, or biomass with environmental variables to predict the distribution of a species in unsampled locations. To produce accurate predictions of occurrence, abundance or biomass distribution, a...

A research survey of Iceland scallops (Chlamys islandica) using a dredge has been carried out by DFO (Fisheries and Oceans Canada) every 1 or 2 years since 1990 in the Mingan Archipelago ( fishing areas 16E and 16F). The main objective of this research survey was to assess Icelandic Scallop...

Layer that includes the known information on the atlantic sturgeon breeding, feeding and concentration areas in the St. Lawrence River and Estuary according to a literature review of documents produced between 1993 and 2003. Additional Information Atlantic sturgeon's breeding, feeding and...

The Canada Nature Fund for Aquatic Species at Risk (CNFASAR) is a contribution program that focuses on providing funding for recovery and threat mitigation activities in nine priority places and to address two marine threats to aquatic species at risk. The Priority Places and Marine Threats layer...

These commercial whale watching data are comprised of two datasets. First, the ‘whale_watching_trips_jun_sep_british_columbia’ data layer summarizes commercial whale watching trips that took place in 2019, 2020 and 2021 during the summer months (June to September). The second data layer,...

The Government of Canada continues to strive to be ever more open and transparent. This means a government that is open by default providing better digital capacity and services for Canadians. Under a modernized Fisheries Act, Fisheries and Oceans Canada (DFO) has made available an online...
