These are the results of the annual DFO survey of key fish stocks. This survey tracks Fisheries and Oceans Canada’s implementation of its Sustainable Fisheries Framework policies.

We assembled productivity (i.e. recruits per spawner) estimates for British Columbian Sockeye, Pink, and Chum Salmon. Annual estimates, by brood year, of spawner numbers, catch, and population and age composition were obtained from regional experts and organized in a simple database. Time series...

The National Aquaculture Public Reporting Data contains information submitted to the Department of Fisheries and Oceans by industry owners or operators as a reporting requirement under the Aquaculture Activities Regulations. Before accessing the dataset for the National Aquaculture Public...

Recruitment overfishing in the Spot Prawn (Pandalus platyceros) trap fishery in British Columbia on the west coast of Canada is managed using a fixed escapement system. Fixed escapement targets in the fishery are set and implemented as the number of female spawners caught per trap in the...

Acoustic telemetry is a widely used method in assaying behavioural dynamics in fishes. Telemetry tags are often surgically implanted in the coelom of the animal and are assumed to have minimal rates of post-release mortality and tag shedding. However, fish are capable expelling tags and...

The data for this study are from a sub-Arctic coastal ecosystem (1000 km2) in the northwest Atlantic. The aim of the collection was to characterize the prey of the larvae of important fish species that occur in Conception Bay, Newfoundland. Plankton was sampled fortnightly from late May until...

Fish health on British Columbia salmon farms is managed throughout the production cycle to maintain healthy fish populations and to identify and address disease occurrences as soon as they arise. Aquaculture licence conditions set out mandatory monitoring and reporting requirements to ensure any...

Salmon Enhancement Program (SEP) facilities are subject to the Pacific Aquaculture Regulations (PAR) under the Fisheries Act. PAR licenses include a production plan, which is developed within a formal integrated planning process involving internal and external consultation. External consultation...

The data tables for post-season production list proposed release targets and the production that actually took place for that brood year. They address production from SEP licensed facilities only, and do not contain production of steelhead or cutthroat which are provincially managed. Post-Season...

Microsatelite frequencies by stock for several pacific marine species of fish.

Fisheries and Oceans Canada's (DFO’s) Atlantic Salmon Watch Program (ASWP) was established in 1991 to study the abundance, distribution and biology of Atlantic salmon in British Columbia and its adjacent waters. The ASWP relies on voluntary reports from Indigenous, recreational and commercial...

The Pacific Region ERAF provides a comprehensive approach for assessing all threats to marine ecosystems by evaluating cumulative risk from multiple activities to multiple ecosystem components for ecosystem-based management (EBM), improving upon international and national best practices in risk...

The Atmospheric Forcing Index (AFI) utilizes standardized scores of the first component from a principal components analysis on the Aleutian Low Pressure Index (ALPI), Pacific Interdecadal Oscillation Index, and the northwesterly atmospheric circulation anomalies for the North Pacific (December...

List of Publications from the Pacific Biological Station and related staff (not including (IOS)).

The mean discharge (m3 s-1) of the Fraser River measured at Hope station. Presented as the mean discharge for an annual year (January through December) and for a flow year (April present year through March next year)....

For health auditing purposes, a farm is considered active once three pens of fish have been present for 30 days, following entry of the first pen of fish at the farm. Fisheries and Oceans Canada (DFO) applies a computerized selection system to randomly select active salmon farms within the fish...

This index measures the relative intensity of the Aleutian Low pressure system of the north Pacific (December through March). It is calculated as the mean area (km²) with sea level pressure <= 100.5 kPa and expressed as an anomaly from the 1950-1997 mean. A positive index value reflects a...

Fisheries and Oceans Canada (DFO) issues licences under Section 56 of the Fishery (General) Regulations to authorize the intentional release and transfer of live aquatic organisms into fish-bearing waters or fish-rearing facilities. The federal-provincial Introductions and Transfers Committee...
