INSECTS FOR A SUSTAINABLE AQUACULTURE 2

Description du projet

Des insectes comme source d’alimentation pour les poissons

L’aquaculture peut accroître les stocks de poissons à l’échelle mondiale afin d’améliorer la sécurité alimentaire et la nutrition. Il s’agit d’un moyen durable de produire des poissons sains tout en préservant les stocks halieutiques sauvages. Cela dit, l’alimentation des poissons d’élevage constitue un défi de taille. La farine de poisson contribue à l’épuisement des stocks halieutiques, car elle absorbe jusqu’à un tiers du poisson capturé dans la nature. En outre, sa disponibilité est limitée en raison des quotas de pêche. La farine de soja, quant à elle, contient des facteurs antinutritionnels pour la plupart des poissons d’élevage. Dans ce contexte, le projet IFASA 2, financé par l’UE, se penchera sur les protéines d’insectes en tant que solution de substitution. Le coordinateur du projet, InnovaFeed, a optimisé le modèle zootechnique de Hermetia illucens (espèce de mouche endémique d’Europe) pour obtenir des protéines d’insectes de qualité destinée à l’aquaculture.

Objectif

The consumption of fish protein is essential to the livelihood and well-being of billions of people worldwide, and aquaculture is a sustainable way to produce healthy fish while preserving wild fish stocks. With a 10% yearly growth over the past decade, aquaculture is one of the fastest growing sector in the food industry. Yet, sector’s expansion and sustainability are challenged by current fish feed limitations. Indeed, fishmeal and soybean meal are the two main ingredients in fish feed formulations and both hold challenges in terms of sustainability and nutritional value:
Fishmeal absorbs up to a third of wild caught fish, contributing to the depletion of fish stocks and its availability is limited due to fishing quotas with a direct impact on price (price rise from 500 euros per ton in 2004 to 1,500 euros per ton today );
Soybean meal contains anti-nutritional factors for most farmed fish and its use for aquaculture increases Europe’s protein deficit and dependency on raw material imports. Today, 80% of protein-rich crops used in Europe for animal feed, i.e. mostly soybean meal, are imported .

Fish feed manufacturers and fish farmers are seeking innovative ways to increase the nutritional value of their products while reducing the environmental impact of their supply chain. Insect protein stands out as one of the best solution to address this need and drive the development of sustainable aquaculture. Insect protein has demonstrated excellent nutritional performance with less pollutants than fishmeal (heavy metals, pesticides residues, PCBs, dioxins), restoring a natural diet for farmed fish that eat insects in the wild (e.g. salmon, trout, seabass). InnovaFeed’s insect protein is an alternative source of quality protein that will address the fish feed challenge and support the aquaculture sector’s growth.

InnovaFeed has optimized the zootechnical model of Hermetia illucens (European endemic fly species) to achieve maximum productivity and consist
