The Philippines, notorious for inventing and being the primary user of cyanide fishing?
Japan, largely responsible for decimating bluefin tuna population in the Pacific?
Canada and the US, responsible for polluting waterways and putting salmon fisheries on the verge of collapse? Maybe for culling Northern Cod populations to 1% of their historical levels.
Oh, you mean China, which produces 73% of it’s fishery output from aquaculture. China accounts for 19.2% of global catch (i.e., fishing) and 61.5% of global aquaculture.
