The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Status of major fish stocks indicator The indicator reports the status of major fish stocks. Federal biologists use a variety of scientific methods to assess fish stock levels and assign 1 of 3 stock status zones (Healthy, Cautious or Critical) by comparing the size of the stocks to reference points. If there is insufficient information to be able to determine the stock status zone, the status is uncertain. Stock status is an important element of the precautionary approach. 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 data sources and details on how those data were collected and how the indicator was calculated.
