“…However, food safety is of upmost importance, therefore diligent research and stringent regulations must be required before commercialization of GM products. The balance between nutritious, safe food production and maintaining environmental sustainability will rely on our ability to use new technologies to improve farming practices, and our ability to use as few resources as possible to provide for our society [80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95].…”

Global aquaculture production has increased in recent years and it is predicted that aquaculture will provide the most reliable supply of seafood in the future. However, there are many controversial issues in aquaculture regarding food safety, nutrition, and sustainability; many of which are directly related to the nutrition and feeds for farmed fish. These nutrition-related issues must be considered in order to achieve balance in safe and nutritious food production and sustainability in aquaculture. This review highlights recent studies and discusses new and innovative aspects in fish nutrition. Some issues in the area of fish nutrition require consideration and improvement, such as: feed and nutrient efficiency, overfeeding and waste, fish meal and fish oil replacements, fish health, biotechnology, and human health concerns. The findings reviewed in this manuscript demonstrate promise toward improvement of the aquaculture industry through nutrition. This review is an update in fish nutrition research, and provides insight on the progression and evolution of this field in order to meet the needs of the industry with the purpose to achieve a balance in seafood production and environmental sustainability. The outcome of this review encourages the use of biotechnology as a tool to meet seafood production and environmental sustainability, in order to ensure global food security in the future and to improve our resource use.

“…The optimal dietary protein level is dependent on a number of factors including the abalone species, abalone size, water temperature, ingredient digestibility and dietary energy level Bautista-Teruel and Millamena, 1999;Stone et al, 2013). The abalone industry is relatively new compared to other aquaculture sectors such as fin fish, which have successfully developed pre-starter, starter, grower and finisher diets for different grow-out stages (Ng and Romano, 2013;Sarker et al, 2013). There is an increased demand to introduce multi-diet feeding strategies for greenlip abalone by optimising the dietary protein level for each age class and water temperature throughout the production cycle.…”

“…Such concerns are not only of spatial character, as e.g. the use of pelagic fish for aqua feed, although a clear trend for a substantial reduction of fish-based ingredients in commercial fish diets can be observed (Tacon and Metian, 2008;Sarker et al, 2013). The growth of marine aquaculture with mainly piscivorous species will therefore also be influenced by the ability to further substitute fishmeal and fish oil in the diets and improving feed conversion ratios (Pelletier et al, 2009).…”

a b s t r a c tThis study examines the spatial occupancy of marine finfish aquaculture in the European Union (EU), identifies geographical clusters and administrative areas where cage aquaculture development is particularly significant and provides evidence on the interactions between aquaculture and the touristic use of the coastline.Despite the increasing demand for seafood in the EU, its aquaculture is not expanding at the same rate (FAO, 2014), and the low number of new licences issued in recent years is a clear sign of the difficulties of the sector to expand.In this study, Google Earth satellite images and GIS methods were used to map and analyse spatial properties of marine finfish aquaculture sites in the EU. The analysis covers ten member states (Cyprus, ) representing around 95% of EU marine finfish aquaculture production by volume, and Turkey.The results indicate that existing marine aquaculture sites occupy around 230 hectares (ha) in Greece, and 34 ha in UK, which represent respectively 28% and 44% of EU marine finfish production by volume. Considering these very low figures of occupied surface, it is difficult to imagine that the expansion of marine aquaculture in the EU would be constrained by a lack of space in absolute terms. Limitations to growth may be better explained by the competition for space which takes place at the local level with more established coastal economic activities. To examine in particular the interactions with the touristic use of the coastline, the analysis considered the distribution of hotels around the aquaculture sites and found that there is evidence of strong negative spatial interaction up to a distance of 3 km. These quantitative findings corroborate more qualitative considerations on the conflicts affecting the establishment of marine aquaculture in specific coastal regions in USA, Canada, Australia and New Zealand described in the literature. Another contribution from this study lies in the identification and mapping of geographical clusters and local administrative units where aquaculture production is particularly significant. Since socio-economic data for the individual aquaculture sites in the EU are not easily accessible, the mapping of EU aquaculture clusters is the prerequisite for further research to understand the local enabling conditions apart from bio-physical conditions which favoured the expansion of aquaculture in specific areas and not in others and identifying examples of best practices for the governance of the sector.
