“…It seems that mechanical treatment methods are generally not applied [18] in the articles reviewed here. Water exchange seems to be widely used in semi-intensive systems in order to improve water quality [20] as well as chemicals such as lime can be added to disinfect and dry semi-intensive ponds [18,21].…”

Aquaculture intensity has been used for years as a means to gauge how much production a site makes using three terms: extensive, semi-intensive and intensive aquaculture production systems. The industry has a relatively coordinated understanding of these terms, but an explicit general definition does not seem to exist. This paper aims to use three kinds of production function groups; the input, treatment and output functions to describe and define the terms extensive, semi-intensive and intensive explicitly. This is done with extensive literature review to find the meaning of the terms. The terms are then mapped onto the three production function groups. The resulting framework accomplishes two things. Firstly, it defines extensive, semi-intensive and intensive aquaculture in terms of production functions. Secondly, it creates an eight level scale, the aquaculture production intensity scale (APIS), that provides three levels of extensive systems, two level of semi-intensive systems and three level of intensive systems. APIS allows mapping of all uses of the terms in current literature to an APIS score, though some results might differ from current usage.

“…emergy yield ratio, environmental loading ratio, emergy sustainability index, emergy investment ratio and others); and (vii) discussion of the results. Recent aquaculture studies applied emergy analysis to evaluate the production of fish (Vassallo et al 2009;Zhang et al 2011), shrimp (Lima et al 2012) and oysters (Williamson et al 2015). In a study that evaluated three fish farm systems, the type of feed was the major difference between them, and the system that used commercial feed showed a higher emergy cost (Zhang et al 2011).…”

Aquaculture is responsible for almost 50% of the global production of aquatic organisms. However, the activity generates residues that cause environmental impacts. Several strategies can be adopted from the planning stage to the residue treatment to reduce these negative impacts. Alternative rearing systems, such as integrated multi‐trophic aquaculture (IMTA), integrated aquaculture‐agriculture systems, recirculation systems (RAS) and biofloc (BFT), can be implemented in place of the traditional monocultures. At the residue treatment stage, the solids particles can be removed by the settlement of suspended solids in tanks or mechanical filters. The reduction in dissolved nutrients is used in biological filters, constructed wetlands or the irrigation of agricultural crops. Finally, we describe the methodologies that are used to estimate the aquaculture environmental impacts. These methodologies allow the stages and processes that have a higher environmental impact in the production chain to be identified. Among them, we can highlight the life‐cycle assessment (LCA), emergy analysis and ecological footprint. The strategies described in this study can contribute to increasing aquaculture sustainability; however, studies should be developed that focus on more than just productivity and profitability, as it is necessary to include social and environmental issues.

“…Rendahnya nilai ELR pada tambak tradisional disebabkan peran sistem alami dalam mendukung produksi serta desain sistem budidaya yang berbeda dalam produksi udang. Perbedaan nilai ELR pada tambak udang disebabkan juga masuknya input air sebagai masukan tak terbarukan (N) dalam perhitungan aliran emergy sehingga nilai ELR menjadi lebih tinggi dibandingkan dengan sistem budidaya perikanan lainnya (Lima et al, 2012).…”

Indonesia should pay greater attention on aquaculture due to a continous decrease in capture fisheries production. Shrimp is an excellent fishery commodity consumption in the global market, but the availability of supply is not yet fulfilled. The supra intensive aquaculture system has believed as a solution method for shrimp production. This study was trying to analyze the energy and emergy flow inside the supra intensive aquaculture system. Further analysis was done with emergy indices calculation to predict the future application of supra intensive system. The result of study shows the energy required in shrimp harvested from supra intensive system (transformity) was 1,12E+10 sej/g shrimps. This number represents it is needed more energy to produce per gram shrimps in supra intensive system compared to conventional shrimp pond in Ecuador and in Brazil. System more likely depend on purchased input which was indicated by very high EIR and ELR but in contrary relatively low EYR. Supra intensive aquaculture systems tend to be unsustainable in the long term by the very low value of ESI.
