The data in the files of this dataset represent the raw and standardized information of the distribution of the number of prey in stomachs of larval fish, the increments widths derived from larval fish, and the mortality rates, that were included in the study by Pepin (2024) into the probability...

Chemical and biological oceanographic conditions observed in the Maritimes Region in 2022 are presented. Surface and deep inventories of nitrate and silicate were near or above normal in the eastern part of the region while the surface and deep phosphate inventories remained near or below normal...

This dataset is a compilation of algae and substrate observations that have been collected on DFO dive surveys between 1996 and 2021. Sources of this data include Marine Invertebrate Section/Shellfish Data Unit biological survey databases held for targeted species observations of green sea...

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...

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...

Fisheries and Oceans Canada is organized into six administrative regions (Pacific, Central and Arctic, Quebec, Gulf, Maritimes and Newfoundland and Labrador). The Canadian Atlantic Quota Report (CAQR) presents the summary of quotas and catches by species for five of these six regions...

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...

Current tables cover the period from 1990 to present. Data are collected by Fisheries and Oceans Canada’s (DFO) regional offices under the authority of the Fisheries Act. Preliminary results for the current year will be posted once the information has been assessed for trends in the catch rates...

Statistics on commercial fishing licenses issued by Fisheries and Oceans Canada in the Atlantic Provinces. You will also find information collected through the registration of commercial fishing vessels. Data are available from 1983 onward.

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...

Created in 2005, Science Advisory Reports include traditional Stock Status Reports, Ecosystem Status Reports, and Habitat Status Reports. Moreover, management strategies, frameworks and guidelines on the assessment or evaluation on specific issues, impacts of human activities on ecosystem...

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...

Data from drifters with deep drogues collected by the Institut für Meereskunde, at the University of Kiel from 1980 to 1996.
