Daily sea surface temperature and salinity observations have been carried out at several locations on the coast of British Columbia since the early part of the 20th century. Observations started at the Pacific Biological Station (Departure Bay) in 1914; 11 stations were added in the mid-1930s and...

This report provides summary fish health data collected by Fisheries and Oceans Canada (DFO) from randomly selected licensed marine facilities culturing salmon in British Columbia (BC). Results of polymerase chain reaction (PCR) screening are provided, as well as a list of the bacterial pathogens...

Fisheries and Oceans Canada’s (DFO’s) Conditions of Licence for finfish aquaculture include requirements to minimize harm to wild fish that swim into facilities. Facility operators must also maintain an incidental catch log, which is a record of wild fish caught at the facility during harvest...

Mortality at salmon aquaculture facilities is closely monitored. As in any population of wild or farmed animals, there are a number of causes leading to death. While in-depth diagnostic testing takes time, carcasses are routinely assigned to a number of defined categories which can help facility...

Salmon escapement data constitute important corporate knowledge which must be adequately maintained and accessible. The Salmon Escapement Database (NuSEDS) is the DFO Pacific Region’s central database that stores individual spawner survey data records, spawner abundance estimates and the linkages...

Fisheries and Oceans Canada’s (DFO’s) conditions of licence for marine finfish aquaculture contain monitoring and intervention requirements to minimize the potential exposure of wild and farmed fish to sea lice. The Industry Sea Lice Abundance Counts report is updated monthly. It shows which...

Fisheries and Oceans Canada’s (DFO’s) Pacific Aquaculture Regulations and Conditions of Licence for aquaculture in B.C. require licence holders to take various fish escape prevention measures, including maintaining infrastructure in a manner to prevent the escape of farmed fish into the...

Marine mammal predator control is governed by the Marine Mammal Regulations under the Fisheries Act. Records of marine mammal mortalities are maintained and results reported publicly. Additional licences can be obtained for control of other species. Fisheries and Oceans Canada works with industry...

The Olympia oyster (Ostrea lurida Carpenter, 1864) is one of four species of oysters established in British Columbia (BC), Canada, and the only naturally occurring oyster in BC (Bourne 1997; Gillespie 1999, 2009). O. lurida reaches the northern limit of its range in the Central Coast of British...

This data set is a generalized characterization of the offshore and inshore environments of Canada’s Pacific Ocean. Compiled from various sources to depict the biogenic habitats, pelagic habitats, and general bottom types such as offshore and inshore by depth strata.

Fisheries and Oceans Canada has conducted a cumulative human impact mapping analysis for Pacific Canada to support ongoing Marine Spatial Planning. Cumulative impact mapping (CIM) combines spatial information on human activities, habitats, and a matrix of vulnerability weights into an intuitive...

A Conservation Unit (CU) is a group of wild Pacific salmon sufficiently isolated from other groups that, if extirpated, is very unlikely to recolonize naturally within an acceptable timeframe, such as a human lifetime or a specified number of salmon generations. Holtby and Ciruna (2007)...

This dataset provides 30-year, 50-year, and 100 year return levels for small craft harbours in British Columbia, relative to the mean sea level over 1993-2020. The return levels are derived from coastal sea levels for the period from 1993 to 2020, simulated using a high-resolution Northeast...

Fishing event (e.g., day, time, location, catch effort), and associated biological data from the Standardized Inlet Survey component of the annual Sablefish Research and Assessment Survey on the British Columbia coast. Introduction DFO and the Canadian Sablefish Association undertake a...

These data sets provide information pertaining to shrimp and bycatch estimates associated with otter-trawling and trapping (November, 2000) and beam-trawling (February, 2001) in Simoom Sound. Data sets were compiled and formatted by Meagan Mak. Abstract from report: As part of a project...

Fisheries and Oceans Canada’s (DFO) Coastal Environmental Baseline Program supports the collection of ecological information on the current state of key coastal ecosystems across Canada. This initiative aims to acquire environmental baseline data (physical, chemical and biological) contributing...

This dataset contains the modelled and observed data used in the publication "Fjord circulation permits persistent subsurface water mass in a long, deep mid-latitude inlet" by Laura Bianucci et al., DFO Ocean Sciences Division, Pacific Region (published in the journal Ocean Science in 2024). An...
