I don't have those numbers, but I can clarify. The 80% decrease was for.... In Canada, we have a number of terrestrial and marine species, and 50%, more or less, of them have shown a decrease. Amongst those, there was a decrease of 83% on average.
That's the summary finding of a report from the World Wildlife Fund published in 2017. This report—I read it a few weeks ago—provides detailed statistics per region and per type of species. For instance, I believe that for fisheries on the east coast and that region it was about a 47% or something decrease. I cannot provide the exact numbers as I don't have the report with me, but those numbers exist.
