GreenFeed4Fish - Turning agricultural waste into nutritious and functional aquafeeds: an eco-innovative approach to upgrade farmed marine fish welfare and quality

Objectives

To explore the potential of agricultural waste as alternative and sustainable aquafeed ingredients with nutritional and functional properties to:

  1. Improve farmed marine fish immunocompetence, resilience to stress and welfare;

  2. Upgrade the quality of farmed seafood products (nutritional value and shelf life);

  3. Promote sustainable and climate-smart production practices in aquaculture that meet the Circular Economy framework and the 2030 United Nations Agenda.

PARTNER INSTITUTIONS

This project counts with the participation of three Portuguese Research Institutions:

1) NOVA.ID.FCT at Campus de Caparica, Caparica

2) Portuguese Institution for the Sea and Atmosphere (IPMA), Algés

3) REQUIMTE at Instituto Superior de Engenharia do Porto (ISEP), Porto

TEAM MEMBERS

This project counts with the participation of a multidisciplinary team composed by 9 team members and 2 consultants. The project research team gathers expertise in marine ecology, aquaculture, food quality, environmental engineering and life-cicle assessment scientific fields

PARTNER COMPANIES

This project has the support of several enterpresis in the agricultural, aquafeeds and processement sectors, namely VGT PORTUGAL, SPAROS and ALIF

News

The team has begun collecting agricultural waste in VGT Portugal, starting with pumpkins and watermelons that did not meet quality standards for the general market. With the beginning of the season, cabbage will also be collected in the coming months.

​

All the collected agricultural waste was transported to IPMA, Algés, where it was washed and frozen. The samples will soon be transferred to LAQV/REQUIMTE at ISEP, Porto, for extract production and bioactivity quantification.

The second collection was successfully carried out at VGT with more pumpkins outside commercial size standards, watermelons that do not meet the quality parameters and, the new agricultural waste of this season, cabbage leaves excluded during processing. These agricultural by-products will soon arrive at ISEP (Porto), where the team will continue the production of extracts for further analysis and application in sustainable aquafeed development.
