It is important to consider salmon farming in the context of global food production, and continue to monitor how salmon stacks up compared to other protein choices.
When compared to chicken, pork and beef, salmon has the most efficient feed conversion ratio. This is due to a couple of factors:
- they are neutrally buoyant, which allows them to have small lightweight skeletons
- they are cold-blooded, which reduces energy lost to staying warm.
This basically means that salmon grows into a food source for us while consuming less food than other proteins.
This, combined with their sleek streamlined shape, also means that they have the highest edible yield out of chicken, pork and beef.
