“…An example is the cultivation of scallop, kelp and abalone in the marine IMTA system of Sungo Bay, China, (Fang et al 1996, Troell et al 2009). The approach is now also becoming widely accepted in western countries (Troell et al 2009, Abreu et al 2011, MacDonald et al 2011) and several pilot experiments using IMTA have recently been conducted in Canada, Scotland and Australia (Stirling & Okumus 1995, Cheshuk et al 2003, Barrington et al 2010). In the Bay of Fundy, Canada, blue mussels Mytilus edulis and kelps (Saccharina latissima and Alaroa esculenta) reared close to Atlantic salmon cages exhibited growth rates that were 46 and 50% higher, respectively, than at control sites.…”

We quantified release rates of carbon (C), nitrogen (N) and phosphorus (P) waste from Norwegian salmon farms in 2009 in order to evaluate the theoretical environmental influence on surrounding waters and the potential for integrated multi-trophic aquaculture (IMTA) driven by salmon aquaculture. Of the total feed input, 70% C, 62% N and 70% P were released into the environment, equivalent to an annual discharge of about 404 000, 50 600 and 9400 t of C, N and P, respectively, based on total salmon production of 1.02 × 10 6 t. We predicted that 48% of feed C was respired as CO 2 , 45% of feed N was excreted as dissolved inorganic N (DIN), and 18% of feed P was excreted as dissolved inorganic P (DIP). Approximately 44% of feed P was released as particles, dominating solid wastes. The mean food conversion ratio (feed supplied per fish produced) of Norwegian salmon farms was 1.16 ± 0.08 SE in 2009. Estimates of the potential for IMTA driven by salmon farming showed a far higher potential for seaweed production based on the released DIN than for mussel production based on released appropriately sized particulate organic carbon (POC). The daily volumetric loading rates of DIN from salmon farms (range for counties: 40 to 501 µg N m −3 d −1 ) were <15% of the natural loading rate of nitrate from deep water, suggesting that the nutrient loading rate is within safe limits.KEY WORDS: Cage aquaculture · Atlantic salmon · Nutrient wastes · Feed conversion ratio · FCR · Integrated multi-trophic aquaculture · IMTA · Seaweed · Blue mussels Resale or republication not permitted without written consent of the publisher

“…Macdonald et al (2011) found that the oyster, Saccostrea commercialis, is effective at reducing total suspended solids, and total N and P released from an Atlantic salmon farm [140]. Studies have also shown significant growth increases in oysters and mussels have been achieved when co-cultured with salmon [140][141][142]. Some studies have suggested that bivalves have the potential to act as a reservoir for finfish pathogens.…”

“…Several studies have shown that bivalves have enormous potential as biocontrollers of fish farm effluent [140][141][142][143]. For example, Reid et al (2010) measured the absorption efficiency of blue mussels (Mytilus edulis and M. trossulus) feeding on Atlantic salmon feed and fecal particulates and found removal rates of up to 54% of total particulate matter [143].…”

“…Nevertheless, it has been shown that bivalves have the capability to reduce the environmental and ecological impacts of aquaculture while at the same time providing a valuable crop for the farmer. Bivalves are therefore ideal candidates for IMTA systems [4,140].…”

Abstract:The demand for seafood products on the global market is rising, particularly in Asia, as affluence and appreciation of the health benefits of seafood increase. This is coupled with a capture fishery that, at best, is set for stagnation and, at worst, significant collapse. Global aquaculture is the fastest growing sector of the food industry and currently accounts for approximately 45.6% of the world's fish consumption. However, the rapid development of extensive and semi-extensive systems, particularly intensive marine-fed aquaculture, has resulted in worldwide concern about the potential environmental, economic, and social impacts of such systems. In recent years, there has been a significant amount of research conducted on the development of sustainable saltwater-based food production systems through mechanical (e.g., recirculatory aquaculture (RAS) systems) methods and ecosystem-based approaches (e.g., integrated multi-trophic aquaculture (IMTA)). This review article will examine the potential negative impacts of monocultural saltwater aquaculture operations and review established (RAS) and novel (IMTA; constructed wetlands; saltwater aquaponics) saltwater-based food production systems and discuss their (potential) contribution to the development of sustainable and environmentally-friendly systems.
