“…The harmful effect of wastes derived from aquaculture __________________ Corresponding editor: Mariel Gullian operations on aquatic environment is often questioned and studied (Yokoyama, 2013;Park et al, 2015). Less than 30% nutrients from the feed can be utilized by fish for growth, whereas the remaining amounts of particulate organic matter (unconsumed feed and fish feces) and inorganic nutrients (fish excretions) are released into water, causing eutrophication, harmful algal blooms, and deoxygenation of the bottom water (Yokoyama, 2013;Irisarri et al, 2015;Martínez-Espiñeira et al, 2015). Rapid water quality deterioration endangers animals living in the aquacul-ture area, often leading to fish diseases and death.…”

“…Several studies on the possible applications of IMTA for land-based, inshore, and offshore systems with special interest in seaweed and shellfish have been examined (Buschmann et al, 2008;Fang et al, 2016;Perdikaris et al, 2016;Neori et al, 2017). The recent research includes a concern on assessing the bio-mitigation efficiency of IMTA based on experiments Irisarri et al, 2015;Martínez-Espiñeira et al, 2015;Milhazes-Cunha & Otero, 2017;Laramore et al, 2018). Nevertheless, due to the complex interactive processes involved in the IMTA, it is questionable whether a relatively accurate assessment of IMTA bio-mitigation effectiveness can be fully achieved through partially balanced experiments (Troell et al, 2009).…”

In general, aquaculture wastes from traditional aquatic organism cultivation rapidly deteriorate the water quality of the surrounding ecosystems, endangering animals living in the area. The integrated multitrophic aquaculture (IMTA) system is a bio-mitigation strategy to alleviate the adverse impacts caused by aquafarming pollutants on the environment and aquatic species. This study provides an overview of the IMTA system, explains the interactive processes among the different trophic levels, summarizes the major practices being followed around the temperate coastal waters with a field case study in Japan, and discusses the assessment of IMTA bio-mitigation efficiency through experimental greatly dependent on the customs and market values in the local IMTA practice. Bio-mitigation efficiency acquired in a land-based experiment exhibits its limitation in approach and conducts a comprehensive analysis on the possibility of applying numerical models to evaluate IMTA effectiveness. The selection of a suitable candidate organism is estimating that in the same or different culture conditions with various biomasses of extractive species. However, in open water experiments, it is difficult to evaluate the bio-mitigation effect of extractive species because the initial biomass ratio (IBR) of the extractive to target species is too small. Alternatively, the possibility of applying existing numerical models to assess IMTA is relatively low. In conclusion, an optimally designed large-scale IMTA experiment is required, in which the IBR of the extractive to target species is adequately considered, and a full-scale IMTA model should be further improved with a database of individual-based submodels for IMTA candidate organisms.

“…high density fish cage cultures, shellfish culture, sea cucumber culture), although a specific assessment of the proposed local IMTA system must be conducted to define the level of compatibility according to the MPA category. For instance, there are interesting cases in Europe and Canada where IMTA is implemented on a pilot scale, but this type of aquaculture has not been able yet to expand for broader application for a number of reasons, including blocking regulations or public perception (Alexander et al, , ; Martínez‐Espiñeira et al, , ). Sufficient attention should be given to biosecurity issues and a full risk analysis should be undertaken (Neori et al, ; Troell et al, ).…”

To meet the Convention on Biological Diversity0 s Aichi Target 11 on marine biodiversity protection and Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans by 2030, there is an urgent need to rethink how best to reconcile nature conservation and sustainable development. 4. It is recognized that aquaculture is an important activity in terms of sustainable development. It can play a role in providing food security, poverty alleviation and economic resilience, in particular for MPA local communities, and contribute to wild stock enhancement, as an alternative to overfishing and for providing services to the ecosystem.5. This study showed that there is a need from both aquaculture and MPA sides for clarity of objectives and willingness for open and extensive dialogue. The paper concludes by describing a number of tools and methods for supporting greater synergies between aquaculture and MPAs.6. The results from this work have already helped to build a common understanding between conservation and aquaculture and initiate a rapprochement for increasing synergies.KEYWORDS aquaculture, ecosystem approach, environmental impact assessment, littoral, marine protected area, ocean, sublittoral

“…This label is therefore simplified to values ranging from A-D. This is comparable to the effect of IMTA as described by Martinez-Espineira et al [21]. In their choice experiment IMTA farms were assumed to reduce waste by assigned values of 10-50% (10% increments) relative to conventional aquaculture farms.…”

“…In addition, a positive consumers' Willingness to Pay (WTP) was identified in several studies for salmon produced in an environmentally friendly manner, similar to what would result in an IMTA scenario (in Scotland by Whitmarsh & Wattage [18], in the US West coast by Yip et al [19] and in Canada by Barrington et al [20]). It is also recognised that in order for IMTA to be accepted, consumers must be able to distinguish between conventionally farmed salmon and IMTA salmon [21]. Eco-labelling is an increasingly used tool to differentiate aquaculture produce and stimulate informed purchasing decisions, thus creating economic incentives for producers to adopt environmentally friendlier technologies.…”

Estimating the Irish public's willingness to pay for more sustainable salmon produced by integrated multi-trophic aquaculture

et al. 2017

Integrated Multi-Trophic Aquaculture (IMTA) has been put forward as a potential sustainable alternative to single fin fish species aquaculture. In IMTA, several species are combined in the production process. Integrating species has a conceivable dual advantage; the environmental impact can be lowered through nutrient cycling and from an economic perspective there is potential for increased efficiency, product diversification and a higher willingness to pay for more environmentally friendly produced salmon. This paper presents the results from a choice experiment which examines whether the Irish public is willing to pay a premium for “sustainably produced” farmed salmon from an IMTA process. Uniquely, an ecolabel was used in the design, based on familiar energy rating labels, to communicate the environmental pressure of fish farming to respondents. The experiment demonstrates that the Irish public has a willingness to pay a price premium for sustainability in salmon farming and for locally produced salmon
