phil heatley aquaculture and the energy comes from?

Aquaculture is just tapping in to the food chain at an earlier level than tuna.

All food-chains are empirical energy chains – Billions of plankton, millions of baitfish, hundreds of tuna.

The thing is finite, due to source. The question then, is what will suffer from our intruding at a lower level, and extracting food energy at that point.

Perhaps we have removed so much up the chain, that there is a bottlenext, and excess.

Perhaps.

But I bet we haven’t thought of it.

At all.
