Harvest levels of key fish stocks

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Harvest levels of key fish stocks indicator compares harvest rates with established harvest limits. These limits are based on scientific information, providing a direct measure of whether we are managing the use of these resources within ecosystem limits. It is one measure of fishing pressure on wild fish stocks. The preservation of the ecological, social and economic value of fish stocks requires limiting harvest. Harvesting above the removal reference or other approved levels, along with other pressures, can reduce the size and productivity of fish stocks, and in the past has even led to their collapse. The harvest rate is the proportion of the stock that is taken from the water, either intentionally or as bycatch. Harvest rates must be adjusted to reflect changing conditions and to protect stocks for the future. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.
