In the face of overfishing because of aquaculture I wondered about this, too. Or what about catching introduced species like the abundant Asian carp to feed salmon or trout in aquaculture (a suggestion I read somewhere recently)?
Angesichts der Überfischung wegen Aquakultur habe ich mich das auch schon gefragt. Oder wie wäre es damit, eingeführte Arten wie die im Überfluss vorhandenen Asiatischen Karpfen zu fangen, um sie Lachs oder Forelle in Aquakultur zu füttern (ein Vorschlag, den ich kürzlich irgenwo las)?
