Fig. 5: EPA + DHA resource use efficiency (RUE) in pond carp fed on supplementary feed (cereals) or natural food (zooplankton, zoobenthos) and intensively farmed salmon fed on a fish oil-based diet.

From: Nutrient footprint versus EPA + DHA security in land-locked regions—more of local pond farmed, imported marine fish or fish oil capsules?

Fig. 5

Legends: c(EPA DHA-CR) = ‘consumable’ EPA + DHA conversion ratio. EPA DHA-CR = ‘gross’ EPA + DHA conversion ratio. EPA DHA-Factor = concentration times higher or lower in the flesh compared to food. Comparison on iso-edible yield basis (60%) of salmon and carp—see Method for clarifications. The same definition of box-whiskers as in Fig. 2.
