Abstract

Aquaculture is a strategic sector that aims to meet the increased demands for healthy food for current and future populations. However, this progression needs to be sustainable, which can potentially be achieved by the implementation of circular practices. Integrated multi-trophic aquaculture (IMTA) systems promote the incorporation of circular principles. Nevertheless, the lack of harmonized definitions and standards impedes the quantification of these circular attributes. This study aims to explore the potential principles embedded in IMTA and the existing alternatives to quantify circularity. Two basic pillars (nutrient management and resource use efficiency) were identified as the most relevant circularity attributes for IMTA systems and were quantified through aquaculture-specific indicators. Bioremediation indicators, together with the efficiency indicators in terms of feed, water, energy, and infrastructure materials used, were selected to evaluate the circularity performance of four IMTA trials in three aquaculture facilities in Ireland, Brazil, and South Africa. Salmon, white shrimp, tilapia, abalone, and sea urchins were studied and cultivated together in various combinations with several low-trophic species in these IMTA trials to evaluate the improvement in circularity compared with corresponding monoculture conditions. The results showed an increase in circularity of up to 90% in terms of water recirculation, as well as bioremediation, which was improved by 80%–90%, providing evidence for the potential role of IMTA in the circularity transition.

Estabilitat, Sistema dinàmic, Formalismes lagrangià i hamiltonià, Mecànica geomètrica, Dissipació, Symplectic geometry, Oscil·lacions, Geometria simplèctica, 53 Differential geometry::53D Symplectic geometry, contact geometry [Classificació AMS], Varietat simplèctica, Matemàtiques i estadística::Geometria [Àrees temàtiques de la UPC], Varietat de contacte
Abstract

Aquest treball de fi de grau presenta la geometria de contacte, una branca de la geometria diferencial que permet descriure geomètricament certs sistemes dinàmics com ara sistemes amb dissipació. Aquesta formulació permet descriure tant sistemes hamiltonians com lagrangians. S'estudiarà el procés complet des de la formulació geomètrica fins a l'estudi de les equacions de moviment des del punt de vista dels sistemes dinàmics. El primer capítol serà un repàs de la formulació geomètrica clàssica, mentre que el segon presentarà les nocions bàsiques de la geometria de contacte: les varietats de contacte, el formalisme hamiltonià de contacte i el formalisme lagrangià de contacte. En el tercer i últim capítol es realitza l'estudi dinàmic de les equacions de moviment obtingudes i estudiarem l'efecte que hi provoquen la dissipació, l'excitació i una combinació (pseudo)aleatòria d'aquestes.

Abstract

The Horizon 2020 project IMPAQT aims to support Integrated Multitrophic Aquaculture (IMTA) by developing modelling tools, as well as new and emerging technologies, which enable economically, environmentally and socially sustainable aquaculture development throughout the EU. A tailored made platform for IMTA production systems have been defined in the project, looking at end-users and stakeholders needs. To do so, several requirements have been defined, identifying the attributes that aim at boosting the sustainability within the multi-trophic production systems. These attributes are also expected to maximize the social, economic and environmental benefits of the new aquaculture systems.

Abstract

The Horizon 2020 project IMPAQT aims to support Integrated Multitrophic Aquaculture (IMTA) by de-veloping modelling tools, as well as new and emerg-ing technologies, which enable economically, envi-ronmentally and socially sustainable aquaculture development throughout the EU. IMTA is expected to improve circularity and reduce the environmental footprint of conventional aqua-culture, thus contribute to the optimization of Eco-system Services (ES) such as food, clean water, flood protection or cultural heritage.
