New range of practical feeds for European seabass using animal ingredients

Objectives and main results

The sustainability of European aquaculture, both economic and environmental, relies on the compound feed industry’s ability to place on the market high quality “premium” diets that are able to respond to consumer demands, at the most competitive prices while respecting the environment. Thus, and considering the urge to find protein and lipid sources as an alternative to the traditional, unsustainable and expensive sources, the promoter SORGAL, an aquafeed producer, together with two industrial partners involved in the treatment and recovery of animal by-products (AVICASAL and SAVINOR) partnered with a R&D unit (ICBAS – University of Porto) selected by its ability to develop technical-scientific solutions. These solutions will be used internally by the consortium enterprises, but also externally by other companies, through the extensive dissemination of the obtained results.

This consortium, which composes the ANIMAL4Aqua project, seeks synergies with the goal of promoting and stimulating innovation through: 

1. The identification and valorization of locally produced land animal ingredients with the most suitable profile for European seabass, a species of high commercial value. Terrestrial ingredients obtained from processed animal by-products, or from insect production, will be tested as fishmeal and fish oil replacements in diets for European seabass. The economic and ecological impacts associated with the use of the various ingredients will also be assessed.

2. The development of a new, more sustainable, range of aquafeeds, specific for European seabass, with competitive prices and resulting in better performance – incorporating the best technical solutions will allow the creation of a new range of high performance feeds for European seabass, enhancing the zootechnical performance of this species and ensuring the nutritional and organoleptic characteristics of the final product.
