“…As the total impacts decrease, the relative contribution of the end user node increases (reanalysis of [41], log-log correlation, df = 6, r 2 = 0.90). A similar result was found in assessing the two nodes of production and distribution [15]; as the total impacts decreased, a greater proportion of the impacts were shifted to categories outside of production. In energy intensive fisheries such as lobster, the overall energy use at the end user is still the node with the second greatest level of impacts, but it is far less critical compared to the role of the end user in the overall sustainability of cod ( Figure 5).…”

“…Any unified sustainability discourse will need to account for this diversity of production. In addition, a broad scope of seafood sustainability should include environmental, social, and economic assessments of the production method, plus assessments relating to how the seafood is processed [14], distributed [15], packaged [16,17], sold [18], and finally consumed [18]. What's more, the linkages between nodes from producer to consumer need to be transparent to gain the maximum sustainability benefits [19].…”

Globally, seafood is an important protein source because it is a nutritious food source produced with relative efficiency compared to other proteins. Because of problems related to overfishing and deleterious environmental impacts, over the last decade, non-governmental organizations (NGOs) have increased their focus on seafood sustainability while businesses have incorporated this issue into their corporate social responsibility (CSR) reporting. Sustainability is a concept that can be addressed in terms of scale of issues considered (narrow vs. broad) as well as the scope of how they are measured (undemanding or demanding). Currently, the message of seafood sustainability is becoming complicated in that the journey toward sustainability is being referred to as having achieved a state of sustainability. In addition, companies making a "sustainable" declaration are often at different points in the "scale/scope" arena. As a result, buyers, retailers and consumers have difficulty differentiating between these products. Furthermore, they often assume that a "sustainable" product has no further need for improvement, when in fact this is rarely the case. This change in reference from a continual process (a journey) to a static point (it is sustainable) limits further advances in seafood sustainability and the drive for continual improvement. Herein, the "Law of the Minimum", growth toward an end goal will occur until one factor becomes limiting, OPEN ACCESSSustainability 2012, 4 2039 is adopted as an analogy for sustainability. By refocusing the sustainability discussion on a progressive series of challenges to be met, the discussion will return to the journey as the central point. Doing so will help refresh the dialogue around seafood, and to create new opportunities for improvement.

“…This last factor is a crucial determinant of environmental disturbances exerted by respective systems. Besides, according to Tlusty and Lagueux (2009) feed is a significant energy component of aquaculture production that needs to be partially or completely replaced in order to assure an energetically responsible manner for future aquaculture development.…”

“…They also suggested that food miles (how far food travels) is not a good metric for quantifying the sustainability of food production and travel. Tlusty and Legueux (2009) made the point in their work that multiple modes are often used to distribute seafood, such as ships, trucks, and airplanes, which have different energy intensities. Farmery et al (2014) studied the life cycle environmental impacts of wild caught Tanzanian southern rock lobster and found that the international air freight of the live lobsters contributed significantly to both the global warming potential and total environmental impacts.…”

“…Aquaculture systems, in which freshwater and saltwater fish, crustaceans, and mollusks are grown in captivity, can reduce the distance that seafood travels prior to reaching the consumer if located near areas of consumption (Tlusty and Legueux 2009). These systems have the potential to increase fish consumption, conserve wild fish stocks, reduce food waste, and reinvigorate local economies.…”

Global population growth will increase pressures on current food systems in order to supply adequate protein and produce to the increasingly urban world population. The environmental impact of food production is a critical area of study as it influences water and air quality, ecosystem functions, and energy consumption. Aquaponics (in which seafood and vegetables are grown in a closed‐loop system) has the potential to reduce the environmental impact of food production. A review of the current environmental and economic considerations is provided in order to identify current research gaps. Research gaps exist with respect to 1) diversity of aquatic and plant species studied; 2) inconsistent bounds, scope, and lifetime across studies; 3) diverse allocation of the environmental and economic impacts to the coproducts; 4) scale of systems considered; 5) transportation of produced food; and 6) presence of heavy metals, pests, and pathogens with human health implications. These aspects require increased attention to close the existing gaps prior to widescale deployment of these systems for increased sustainable food production toward satisficing human needs.
