The objective of this project was to gather data to develop a model of the food web of the lower trophic levels of the nearshore area of the Beaufort Sea. Sampling took place from 2005 to 2008 using the CCGS Nahidik. The multidisciplinary character of the Nahidik program produced measurements of biology/ecology (primary production, phytoplankton, zooplankton, benthos, fish), chemical and physical oceanography, contaminants, geology and hydro acoustics. The data were collected in July and August of each year.

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 not available. For the "Region" column specifically, "NA" indicates that the location is outside stock assessment region boundaries.

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 to improve marine mammal deterrent and control measures.

Extreme water level along the marine coastline is a result of a combination of storm surge, tides, and ocean waves. Future projections of climate change in the marine environment indicate that rising sea level and declining sea ice will cause changes in extreme water levels, which will impact Canada's coastlines and the infrastructure in these areas. Understanding these changes is essential for developing adaptation strategies that can minimize the harmful effects that may result. CAN-EWLAT is a science-based planning tool for climate change adaptation of coastal infrastructure related to future water-level extremes and changes in wave climate.

This report provides a summary of sea lice mitigation events reported by marine finfish aquaculture companies in British Columbia to Fisheries and Oceans Canada (DFO). A sea lice mitigation event is any measure that is used to bring the sea lice abundance at a facility below the threshold of three motile salmon lice (L. salmonis) per fish. These mitigation measures include in-feed, mechanical removal, medicinal or non-medicinal bath treatments, or harvest. Salmon farmers must monitor the effectiveness of treatments and report reduced efficacy to the Department.

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 Fisheries Act (FA) Registry that facilitates access to data and information, including geospatial data, about projects as well as regulatory process information. The new online version of the FA Registry is now available to Canadians.
