“…Cage aquaculture can release a considerable amount of biogenic waste such as organic wastes and inorganic nutrients that are generated in the production process (Troell & Norberg 1998, Cheshuk et al 2003, Vassallo et al 2006, Redmond et al 2010. The rapid expansion of cage aquaculture has raised a general concern about increasing amounts of solid and dissolved nutrients released to the aquatic environment (Perez 2002, Whitmarsh et al 2006, Redmond et al 2010, Azevedo et al 2011, Skriptsova & Miroshnikova 2011.…”

“…The salmon aquaculture industry has taken a number of steps to reduce nutrient release from salmon farming facilities. These efforts include optimizing feed composition and improvements in feed digestibility and feeding technology (Cheshuk et al 2003, Islam 2005. These measures reduced nutrient loading and mitigated pressure on the environment.…”

“…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

“…Organic enrichment is recognized as the most important problem associated to marine aquaculture (Mirto et al, 2010;Troell et al, 2003) as a direct result of the release of dissolved and particulate nutrient loads, especially organic phosphorous and nitrogen in the form of ammonia that might easily induce eutrophication (Karakassis et al, 2000). Uneaten pellet and fresh food supplied at fish cages, together with the excretion products from cultured fishes are the source of the nutrient loads released (Cheshuk et al, 2003).…”

“…The effects of the organic enrichment are widely studied in the Atlantic and the Pacific Ocean, especially in relation to the salmon industry (Brown et al, 1987;Cheshuk et al, 2003;Weston, 1991), however, knowledge of fish farming impacts in the Mediterranean Sea is scarce (Sarà et al, 2004(Sarà et al, , 2006Vizzini & Mazzola, 2004), which have different hydrographic characteristics, such as shallow waters and low current velocity areas, and are characterized by oligotrophic waters.…”

Bio-optical variability at a Vancouver Island aquaculture site

Variability of the particulate beam attenuation, scattering, and backscattering coefficients, along with discrete measurements of HPLC derived pigments and particulate organic carbon, is investigated within and beside a finfish aquaculture cage on the west coast of Vancouver Island, Canada. Large bio‐optical variability was observed over three seasons: fall, spring, and summer. The use of multiple optical proxies for organic particle concentrations, bulk particle‐size distributions, and compositions allowed for the characterization of the particle assemblage over the dynamic conditions. Specifically, in fall, low biological productivity and surface influences from runoff were observed. In the lower‐cage, after feeding the fish, optical proxies suggest the dominance of large particles with high indices of refraction, possibly due to the influence of fish fecal particles. Optical variability in spring was driven by diatom bloom conditions (Chaetoceros and Skeletonema). Strong bio‐optical relationships were observed and the optical proxies suggest a particle‐size distribution (PSD) dominated by large particles with low indices of refraction. In turn, summer conditions displayed noticeably high and persistent particulate backscattering in the surface waters, suggesting the presence of an Emiliania huxleyi bloom. Neither spring nor summer showed distinct influences by aquaculture wastes indicating that optical characterization of particulate waste dispersal is likely constrained to low ambient seston conditions. Outside of these conditions bio‐optical analysis would be beneficial for environmental monitoring of ambient particles moving through aquaculture systems.
