The treasures of a healthy and sustainable ocean

The ocean provides us with food and other resources and services but, although we are often unaware of it, it is finite and vulnerable. Obtaining food requires sustainable strategies and practices, both socio-economically and environmentally. To this end, biotechnological tools are available to facilitate sustainable aquaculture, the exploration of low trophic level fishery alternatives, the improvement of food quality and safety, and the optimisation and innovation in food processing; all within the scope of the circular economy and the challenge of zero pollution. In addition, the engineering of genetic resources (biomimicry, biofuels and bioengineering) and the exploration and management of genetic resources (biodiversity, natural bioactive for pharmaceutical and industrial use) are still marine treasures that we are beginning to discover. These advances are only possible if the health of the ocean is protected in the framework of the emerging "One Ocean - One Health" paradigm. Biotechnology also provides us with tools that contribute to the protection of the health of marine ecosystems (biosensors, biomarkers, bioassays, bioremediation and biorestoration).
