WP3 - Nutrition and Wellness (CLOUD)

The WP3 (CLOUD), focused on nutrition and well-being, is articulated around three generic objectives. The first is related to improving knowledge about the welfare of aquaculture crops through the use of new tools and indicators welfare, within a context of global change. The second objective focuses on improving the nutrition and feeding of farmed animals, through the use of new feed formulations based on blends of alternative raw materials and dietary supplements validated throughout the production cycle, with zootechnical and behavioral data and new molecular biology and microbiota monitoring tools. Finally, the proposal contemplates generating new ingredients for aquaculture feed from the valorization of by-products from fishing and other products and by-products of plant or animal origin with the aim of obtaining compounds that are beneficial to the health and nutrition of the cultivated species.

Objectives

Objective 3.1

Improving knowledge about crop welfare through the use of new tools and indicators in a context of global change.

  • Action 2.11: Improving knowledge about crop welfare and developing systems that allow for continuous and reliable monitoring of: i) new welfare indicators under normal farming conditions and during the slaughter process (where applicable) and ii) developing strategies to improve feed intake and utilization, growth, reproduction and health status (susceptibility to disease) of farmed specimens.
  • Homework 3.1.2: Dermal cortisol
  • Tasks 3.1.3: Monitoring the fatty acid profile.

Objective 3.2

To improve the nutrition and feeding of farmed animals through the use of new feed formulations based on blends of alternative raw materials and dietary supplements validated throughout the production cycle with zootechnical and behavioral data, as well as new molecular biology and microbiota monitoring tools.

  • Action 2.12: Improving fish nutrition and feeding through the use of new feed formulations based on mixtures of alternative raw materials (insect proteins, polychaetes, algae extracts, yeasts, bacterial proteins, etc.) and dietary supplements (probiotics, prebiotics, symbiotics, probiotics), validated throughout the production cycle with zootechnical and behavioral data (intake, physical activity, space occupation, etc.) and new molecular biology and microbiota monitoring tools as a marker of the general condition of the fish.
  • Homework 3.2.2: Development of sustainable feed for shrimp.
  • Homework 3.2.4: Characterization of the palliative effects of dietary probiotic inclusion on chronic stress and animal welfare in Mediterranean species culture (gilthead seabream, sea bass, croaker, yellowtail).

Objective 3.3

Generate new ingredients for aquaculture feed by recycling fishery waste and other plant and animal products and byproducts to obtain compounds of interest to the health and nutrition of farmed species.

  • Action 2.13: Generation of new ingredients for aquaculture feed by recycling fishery waste and other plant or animal by-products, with the aim of obtaining compounds of interest to the health and nutrition of farmed species through the application of biotechnological tools.
