Professor David Little of the University of Stirling, recently reflected on ways that aquaculture can produce a greater amount of animal product for the same energy inputs.
Writing on the Global Food Security blog, he explains that producing, distributing and consuming food accounts for 20-25% of energy consumption in developed countries. The largest energy investments are made to produce protein-rich produce such as meat and fish.
He argues that ‘aquaculture can produce a greater amount of animal product for the same energy inputs than other forms of animal-sourced food.’
However, to do so, the aquaculture industry must ensure that it ‘remains sustainable and that energy input compared to output is kept low.’
‘Learning from the innovations of the producers themselves and combining this knowledge with that of scientists and business is likely to produce the highest gains.’
‘Considering aquaculture from a value chain perspective is critical to assessing energy efficiency…
