“…Biofouling development reduces the water flow inside the fish cage forcing farmers to clean and change polymer nets frequently, or use antifouling coatings, thus, increasing operational costs (Berillis et al, 2017). Antifouling coatings are discarded every year producing toxic effects because of the release of their main active ingredients to the environment (copper oxide, cadmium, and zinc) (Kalantzi et al, 2016).…”

Aquaculture is one of the fastest growing food production sectors and has great potential for food security and livelihoods. However, it generates concerning consequences for the environment, including chemical and biological pollution, disease outbreaks, unsustainable feeds and competition for coastal space. Recent investigations are focusing on sustainable techniques (e.g., polyculture, offshore facilities) to improve the relationship between the industry, environment and society. This review provides an overview of the main factors of ecological concern within marine finfish aquaculture, their interactions with the environment, and highlights sustainable alternatives that are currently in use or development. Adequate environmental monitoring and location of farms, the reduction and exploitation of wastes and chemicals being used is crucial to ensure the growth and continuity of aquaculture production.

“…Specific growth rates of gilthead seabream in antifouling treated (TNN +AF ) and copper alloy mesh (CAM) pens (a) and SGR relative to the control group with non-antifouling treated polymer net (TNN -AF ) (b). Specific growth rate (SGR, % growth/day) = ((lnW final -lnW initial )/(t 2 -t 1 ) x 100 Relative SGR (RSGR) = SGR x 100 / SGR nets leading to depressed dissolved oxygen concentrations inside the pens, affecting fish welfare due to a possibly increased stress environment (Brooks & Mahnken, 2003;Braithwaite & McEvoy, 2005;Lader, Dempster, Fredheim, & Jensen, 2008;Nys & Guenther, 2009;Fitridge et al, 2012;Berillis, Mente, & Kormas, 2017). Apart from these findings, it is likely that the biofouling-free environment in the CAM pen with higher dissolved oxygen levels might have improved fish welfare by facilitating a reducedstress environment with cleaner and more sanitary culture conditions, induced better utilization of diets for growth instead of stress accommodation over the traditional nylon pens as also reported by Braithwaite et al (2007), Fitridge et al (2012).…”

“…The concentration of metallic elements in sediment near fish farming sites, for instance, has attracted public concern over environmental sustainability. One way to alleviate this concern and eliminate the metallic elements is by using copper-alloy aquaculture nets [7]. These nets do not require antifouling paint treatment, and the used net can be recycled into new nets.…”

A New Ecological Paradigm scale was used as a measurement tool to determine consumer perception of the environment through the context of red seabream (Pagrus major) aquaculture and the use of copper-alloy nets. To identify the underlying dimension of consumer perception, exploratory factor analysis was conducted, which showed that consumer perception comprised two dimensions—nature and balance, and human dominance—yielding two indicators as independent variables for a contingent valuation method estimation. The estimation results indicate that demographic variables and one consumer perception variable (i.e., the human dominance indicator) are insignificant. However, the economic variable, one consumer perception variable (i.e., nature and balance), and seafood preference are significant. Finally, willingness-to-pay was estimated for sustainable aquaculture products by comparing the mean willingness-to-pay within New Ecological Paradigm-level groups.
