Industrial-scale aquaculture production magnifies environmental degradation, according to the first global assessment of the effects of marine finfish aquaculture (e.g. salmon, cod, turbot and grouper) released today. This is true even when farming operations implement the best current marine fish farming practices. Dr. John Volpe and his team at the University of Victoria developed the Global Aquaculture Performance Index (GAPI), an unprecedented system for objectively measuring the environmental performance of fish farming.
“Scale is critical,” said Dr. Volpe, a marine ecologist. “Over time, the industry has made strides in reducing the environmental impact per ton of fish, but this does not give a complete picture. Large scale farming of salmon, for example, even under even the best current practices creates large scale problems.
