The organic certification system is the most advanced and long-established system of quantified or controlled environmental agriculture on earth.  It gets unfairly criticised from all angles but that’s not what we are covering here!  About 50% of the world’s human consumption seafood is actually farmed, i.e. it originates from aquaculture.  As it stands all our seafood currently is from wild caught fish.  Organic is a farming standard and wild caught produce cannot be labelled organic because it isn’t farmed – by definition.
