“…Installations and monitoring equipment have evolved considerably, and large-scale units have been installed for different freshwater species (notably for salmon juvenile production, eels, African catfish, barramundi and tilapia). State-of-the-art systems use approximately 500 litres of water per kg production, but with increased capital and energy costs (Verdegem et al 2006;Martins et al 2010). …”

This review paper examines the structure of the EU aquaculture sector, the contribution it makes to the EU economy and the policy environment for past and future development. The primary analysis uses statistical data from the Food and Agriculture Organization of the United Nations which has been re-categorized according to species groups established by the European Aquaculture Technology and Innovation Platform (EATiP) and by culture system type using expert knowledge. Additional data sources for the analysis include the European Market Observatory for Fisheries and Aquaculture Products (EUMOFA) and the European Commission Scientific, Technical and Economic Committee for Fisheries. EU aquaculture production was 1.34 million tonnes in 2012 with a first sale value of €4.76 billion. Shellfish comprised 45 % by volume and 28 % by value; marine fish 30 % by volume and 53 % by value; and freshwater fish 25 % by volume and 19 % by value. The total production volume has actually fallen slightly from 1.4 million tonnes in 2000, whilst the value has increased significantly from 2.79 billion in 2000, mainly due to a growth in Atlantic salmon production. Five countries accounted for around 78 % of the direct output value of EU aquaculture in 2012, the UK, France, Greece, Italy and Spain. Around 50 % of the direct output value was generated using marine cage systems (28 % by volume), whilst less than 3 % of value was generated in recirculated aquaculture systems (\1.5 % by volume). Around 5 % of value was contributed by extensive to semi-intensive inland and coastal pond systems. STECF (2014) estimates there are between 14,000 and 15,000 aquaculture enterprises in the EU employing around 80,000 people, approximately 40,000 full-time equivalent (FTE). The greatest number of jobs (FTE) is provided by the freshwater pond and suspended shellfish sectors due to much lower productivity figures. This could be seen as a social benefit in rural and coastal regions, but corresponding low wages could also discourage young entrants to the industry and lead to dependency on migrant workers. Where efficiencies can be improved through capital investment there is likely to be significant scope for consolidation of ownership as can be observed in the marine fish sector. The output from aquaculture has to find a place within the wider fish and seafood market where volumes are generally inversely related to price. The potential growth of the sector is therefore constrained both in relation to the overall market and with respect to competition from substitute products. These include product from EU capture fisheries as well as imports from third countries (sourced from aquaculture and capture fisheries). Whilst interactions between individual products can be hard to demonstrate, any increase in production costs is likely to lead to lower output volumes, whilst improvements in production efficiency can lead to increased output volumes. With around 60 % of EU fish and seafood supply obtained through imports, and little prospect of incre...

“…Managing aquatic stocks within the carrying capacity of the culture environment, well known to terrestrial pastoralists, has a particular significance for a fish farmer needing to maintain both levels of nutrition and water quality because of the acute impacts of any deterioration in the latter on the survival and growth of the stock (80) . Access to plentiful water at low-cost and good system design that allows for removal of solid wastes are critical, but improvements in feeds and feed delivery that reduce waste have also been transformative (78) . This includes better nutritional formulation, pellet integrity and feed systems, all of which have reduced waste and improved feed efficiencies.…”

“…However, fed fin-fish and crustaceans both have varying dependencies on freshwater, whether grown either in the marine or freshwater environment related firstly to feed provision and secondly to environmental services. The water required for the environmental services; oxygen, support and dispersal of wastes, remains mostly in the biosphere and may then become unusable for other purposes such as for drinking but may also be enhanced as a source of nutrition for integrated agriculture or unaffected for use in industry (1,66,78) . How usable it is may depend on the intensity of aquaculture and the level of subsequent dilution.…”

Aquaculture: a rapidly growing and significant source of sustainable food? Status, transitions and potential

2016

The status and potential of aquaculture is considered as part of a broader food landscape of wild aquatic and terrestrial food sources. The rationale and resource base required for the development of aquaculture are considered in the context of broader societal development, cultural preferences and human needs. Attention is drawn to the uneven development and current importance of aquaculture globally as well as its considerable heterogeneity of form and function compared with established terrestrial livestock production. The recent drivers of growth in demand and production are examined and the persistent linkages between exploitation of wild stocks, full life cycle culture and the various intermediate forms explored. An emergent trend for sourcing aquaculture feeds from alternatives to marine ingredients is described and the implications for the sector with rapidly growing feed needs discussed. The rise of non-conventional and innovative feed ingredients, often shared with terrestrial livestock, are considered, including aquaculture itself becoming a major source of marine ingredients. The implications for the continued expected growth of aquaculture are set in the context of sustainable intensification, with the challenges that conventional intensification and emergent integration within, and between, value chains explored. The review concludes with a consideration of the implications for dependent livelihoods and projections for various futures based on limited resources but growing demand

“…Approximately 1 g of sample was subjected to wet mineralisation using HCl, H 2 SO 4 , HNO 3 and the macro and micro element contents were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES; Varian-Vista). The working conditions of ICP-AES were as follows: RF power, 0.7-1.5 kW (1.2-1.3 kW for axial); plasma gas flow rate (argon), 10.5-15 l/min (radial) and 15 l/min (axial); auxiliary gas flow rate (argon), 1.5 l/min; viewing height, 5-12 mm; copy and reading time, 1-5 s (Max.…”

As the world's fastest ongrowing sector in food production, aquaculture has remarkable priority and needs technological improvements and new candidate fish species to overcome some limitation factors. Considering these issues, this study based on determining the flesh quality in terms of nutrient and mineral element composition of two potential fish species, common dentex (Dentex dentex) and greater amberjack (Seriola dumerili), in recirculation aquaculture system (RAS). On the nutrient basis, the dry matter content of 28.82% and fillet yield with a value of 53.28% of Dentex dentex were found significantly higher than (P<0.05) Seriola dumerili. Crude protein and lipid values demonstrated slight but insignificant differences between the species. Among the macro elements of K and Mg and micro elements of Cr, Mn and Ni were noticeably higher in common dentex than greater amberjack, but Zn level was present almost double amount in amberjack (P<0.05).
