I understand the logic of this phrase, but I don't see Cousteau eating a lot of herbivorous fish in his films. When they fish and cook fishes in the Calipso, are often from carnivorous species. Because carnivorous fish are delicious, and herbivorous fish often just so-so. There is not reason to put your money in a product that nobody will buy.
On the other hand, Tilapia needs proteins. Few animals can trive eating just its own discarding products, void for definition of anything that would merit to be recicled by the fish metabolism.
If their fish (or cattle, or poultry) is so hungry that start to eat their own excrement, they are just making a very poor product, and scamming their customers.
