Exploring the sustainability of aquaculture in Australia

[cottrellr]

Thinking of exploring the relative changes in sustainability of Australian aquaculture - need to find something analogous to the stock assessments to fisheries, in that it shows the relative change in improvement or decline through time (not relative to other countries).

Thinking of doing this through a few trends (all to do with feed because it's 80% of impacts). So temporal changes in:

• The proportion of the aquaculture sector that is fed (a general indicator of resource intensiveness of the sector)
• Feed conversion ratios for each taxon (an indicator of resource efficiency)
• Effective trophic levels for each taxon (an indicator of embedded ecosystem energy)

I'm only thinking of going down this route because their is no temporal data on sustainability metrics in terms of LCA (ghg, nutrients etc), and it is often poor in terms of species level data. Or do you think better to just discuss through a synthesis of literature?

I think it's a good idea if we can find the data. I'll make it my mission tomorrow :)
