Aquaculture results in a large variety of environmental impacts ranging from water and land consumption, desertification, eutrophication to pollution (Naylor et al., 2000). These impacts can affect the human health either directly or indirectly. Consequently, the challenge lies in the development of more sustainable culture techniques to guarantee high-quality food and to limit the environmental impacts simultaneously. Aquaponics, an integrated system that combines recirculating aquaculture with hydroponic production, is considered an innovative and sustainable solution (Tyson et al., 2011). A well-managed aquaponics could improve nutrient retention efficiency, reduce water usage and waste (mostly nutrients) discharged in the environment, and improve productivity by cultivating two cash crops (Tyson et al., 2011). It is generally believed that aquaponics, with concomitant nutrients recovery, will become one of the widely accepted methods of sustainable food production in the next future (Hu et al., 2012). This project aims at investigating the following aspects of aquaponics: 1. Evaluating the feasibility of marine species farming in aquaponics using plant based diets as food, that are considered more sustainable respect to fish meal based diets. 2. Enhancing the productivity of aquaponics by exploiting commercially attractive euryhaline species. 3. Increase the knowledge on nutrients behaviour in water and their effects on the quality of plants cultivated in freshwater aquaponics as starting point for future application in marine aquaponics. 4. Managing the infection of Amyloodinum ocellatum in European sea bass reared in marine aquaponics, using freshwater as therapy and avoiding the use of chemicals which are normally discouraged in the aquaponics approach.
Le pratiche di acquacoltura si traducono in una grande varietà di impatti ambientali che includono consumo di acqua e suolo, desertificazione, eutrofizzazione ed inquinamento (Naylor et al., 2000). Questi impatti possono avere effetti sulla salute umana sia direttamente che indirettamente. La sfida risiede nello sviluppo di tecniche di allevamento maggiormente sostenibili che garantiscano cibo di alta qualità limitando gli impatti ambientali. L’acquaponica, un sistema integrato che combina l'acquacoltura a ricircolo con la produzione idroponica, è considerata una soluzione innovativa e sostenibile (Tyson et al., 2011). L’acquaponica potrebbe ridurre il consumo di acqua e gli scarti (per lo più sostanze nutritive) delle normali pratiche di acquacoltura, e migliorare la profittabilità coltivando due colture da reddito (Tyson et al., 2011). Si ritiene che l’acquaponica diventerà uno dei metodi maggiormente accettati per la produzione alimentare sostenibile nel prossimo futuro (Hu et al., 2012). Questo progetto si propone di indagare i seguenti aspetti dell’acquaponica: 1. La valutazione della fattibilità dell’allevamento di specie marine in acquaponica nutrite con diete a base vegetale, considerate più sostenibile rispetto alla diete a base di farina di pesce. 2. Il miglioramento della produttività dell’acquaponica sfruttando specie eurialine di interesse economico, in combinazione con piante alofili edibili. 3. Aumentare le conoscenze sul comportamento di nutrienti in acqua e dei loro effetti sulla qualità delle piante coltivate in acquaponica di acqua dolce come punto di partenza per future applicazioni in acquaponica marina. 4. Gestire l'infezione di Amyloodinum ocellatum in spigole allevate in acquaponica marina, utilizzando acqua dolce come terapia ed evitando l'uso di sostanze chimiche che sono normalmente scoraggiate nell'approccio acquaponico.

Abstract
Aquaculture results in a large variety of environmental impacts ranging from water and land consumption, desertification, eutrophication to pollution (Naylor et al., 2000). These impacts can affect the human health either directly or indirectly. Consequently, the challenge lies in the development of more sustainable culture techniques to guarantee high-quality food and to limit the environmental impacts simultaneously. Aquaponics, an integrated system that combines recirculating aquaculture with hydroponic production, is considered an innovative and sustainable solution (Tyson et al., 2011). A well-managed aquaponics could improve nutrient retention efficiency, reduce water usage and waste (mostly nutrients) discharged in the environment, and improve productivity by cultivating two cash crops (Tyson et al., 2011). It is generally believed that aquaponics, with concomitant nutrients recovery, will become one of the widely accepted methods of sustainable food production in the next future (Hu et al., 2012). This project aims at investigating the following aspects of aquaponics: 1. Evaluating the feasibility of marine species farming in aquaponics using plant based diets as food, that are considered more sustainable respect to fish meal based diets. 2. Enhancing the productivity of aquaponics by exploiting commercially attractive euryhaline species. 3. Increase the knowledge on nutrients behaviour in water and their effects on the quality of plants cultivated in freshwater aquaponics as starting point for future application in marine aquaponics. 4. Managing the infection of Amyloodinum ocellatum in European sea bass reared in marine aquaponics, using freshwater as therapy and avoiding the use of chemicals which are normally discouraged in the aquaponics approach.File | Dimensione | Formato | |
