Pacific Herring spawn index data for British Columbia from 1951 to present. Note that the spawn index is a relative index of spawning biomass. In addition, “NA" indicates that data are unavailable because they are either incomplete or withheld; contact the custodian for more information. For the...

The data in this layer represents habitat suitability of soft-shelled clams (Mya arenaria) in the DFO Maritimes region, and was developed using an interdepartmental approach. Substrate classification data as well as bathymetric data for the Region were used to identify potential habitat for...

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...

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...

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...

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....

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.

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...
