Green approaches for sustainable aquaculture: morpho-functional studies for the assessment of fish health and muscle development.

The aim of the project will assess two important aspects for sustainable aquaculture: 1) the use of alternatives protein sources in replacing fishmeal by optimizing feeding practices through the assessment on the intestine, muscle development and growth, using morphological and molecular analyses. 2) the study of a photocatalytic wastewater remediation system and its impact on the health and development of fish early stages and late grow-out stage.
According to the Food and Agriculture Organization, by 2050 we will need to produce 60 percent more food to feed the world population. In this context, aquaculture will possibly play a fundamental role in supplying high-quality protein for humans, as fish in aquaculture systems represent very efficient converters of feed into protein. Aquaculture presents a lower carbon footprint compared with other terrestrial animal production systems but there are still several fields of improvement in terms of sustainability. The characteristics of sustainable aquaculture are mainly based on two fundamental parameters: 1) the control of the release of physical and chemical substances into the environment through farms wastewater; 2) the protection of marine fish natural stocks, by replacing fishmeal with alternative protein sources in the diet of farmed fish. Why Focusing on Muscles? The skeletal muscle of fish species for human food represents 35 to 60% of their body mass and it is known that the surrounding environment determines the rate of myogenesis, patterns of gene expression, and the number and size of muscle fibers and it also influences protein turnover and the efficiency of protein deposition. When environmental treatments and nutritional interventions reach productive efficiency, with specific morphological characteristics of the fibers, it improves meat quality.
For these reasons, the strategic guidelines for sustainable and competitive aquaculture contribute to the European Green Deal through its interactions with the environment and the health and nutrition of farmed fish. The research will be partly carried out in collaboration with Istituto Spallanzani, Microalgae Hub.
