Abstract

Genetically modified (GM) plants were first grown commercially more than 20 years ago, but their use is still controversial in some parts of the world. Many GM plant varieties are produced in large quantities globally and are approved for use in fish feeds both in Norway and the European Union. European consumers, however, are skeptical to fish produced by means of GM feed ingredients. Concerns have been raised regarding the safety of GM plants, including potential toxicity and (or) allergenicity of the novel protein, potential unintended effects, and risk of horizontal gene transfer to other species. This review will present the current state of knowledge regarding GM plants as fish feed ingredients, focusing on fish performance and health as well as the fate of the GM DNA fragments in the fish, identifying limitations of the current work and areas where further research is needed. Les plantes geenetiquement modifiees (GM) ont commence; a etre cultiveies commercialement il y a plus de 20 ans, mais leur utilisation reste controversee dans certaines regions du globe. Plusieurs varieetees de plantes GM sont produites en grande quantite a l'echelle mondiale et sont acceptees dans la preparation de la nourriture de poissons, tant en Norvege que dans l'Union europeenne. Les consommateurs europeens maintiennent cependant une certaine inquietude concernant les poissons produits par l'usage d'ingredients alimentaires GM. On a manifeste des preoccupations en ce qui a trait a l'innocuite des plantes GM, en particulier a la toxicite et (ou) l'allergenicite potentielles des proteines nouvelles, aux effets potentiels imprevus et au risque de transferts horizontaux des genes aux autres especes. Notre retrospective resume l'etat actuel des connaissances sur les plantes GM utiliseees comme ingredients dans l'alimentation des poissons, avec une emphase particuliere sur la performance et la sante des poissons, ainsi que sur le sort des fragments d'ADN GM chez les poissons, tout en soulignant les limites des travaux actuels et en identifiant les domaines de recherche additionnelle necessaire.
