Environmental impacts of fish
I am a PhD student attempting to explore the relationship between GHGE and water footprints of food consumed in the UK. I am struggling to find a water footprint value for fish (namely tuna and salmon), presumably due the nature by which are they produced. Am I correct in assuming the water footprint value would be much lower than other animal/plant products since their water footprint would arise from the processing and packaging of the fish etc. only? Does anyone know of any work in this area? Any suggestions would be greatly appreciated.
