However, if we regard this concept of maximum sustainable yield as something radically new, we are mistaken, since that concept, which is a theoretical concept, was always the concept underlying the setting of all quotas and TACs, which could only be set on the basis of that concept.
Toutefois, il est erroné de considérer le rendement maximal durable comme un concept radicalement nouveau. Théorique, ce concept a toujours été le concept sous-jacent de la fixation des quotas et des TAC, qui ne peuvent être fixés que sur la base de ce concept.
