“…However, they allow in-depth analyses of changes and comparable benchmarking on interregional basis (Lasner et al, 2017), which we regard as valuable basis, e.g., for decision-makers. Further, environmental small-scale differences such as those observed for Norwegian salmon farms, where production occurs across a large latitudinal range (e.g., within and outside specific fjords), underscore the importance of making local projections at the farm site level (Falconer et al, 2020). In Norway, farms in the southernmost parts are expected to have a narrower safety margin with respect to temperature increase compared to those located further north (Lorentzen, 2008), and therefore would be important to be included in similar future studies in addition to the northern farm examined in the present study.…”

“…Further, although farms in the north may not be exposed to conditions above the temperature tolerance of salmon, increased temperatures, may also increase the prevalence of disease and parasites, which, historically, were not an issue (Falconer et al, 2020). The colder northern regions of Norway have currently less sea lice occurrence than more southern regions of the country (Jansen et al, 2012).…”

Kreiss et al. Future Socio-Political Scenarios Aquaculture returns, and marketing options as opposed to the direct effect of climate-driven changes in the environment. These results can inform adaptation planning by the European aquaculture sector. Moreover, applying consistent scenarios including societal and economic dimensions, facilitates regional to global comparisons of adaptation advice both within and across Blue Growth sectors.

“…Although this allows reasonable accuracy for the open sea and coarse spatial resolutions, climate modelling in the coastal zone is not as robust [ 32 ]. Downscaled climate projections are generally incapable of capturing the frequent temperature fluctuations of the coastal regions at a scale that would be highly relevant for aquaculture and tend to underestimate summer maxima whilst overestimating winter minima [ 33 ]. Several approaches to correct for this bias exist but require high-quality temperature data at a high spatial resolution.…”

Mediterranean Aquaculture in a Changing Climate: Temperature Effects on Pathogens and Diseases of Three Farmed Fish Species

Climate change is expected to have a drastic effect on aquaculture worldwide. As we move forward with the agenda to increase and diversify aquaculture production, rising temperatures will have a progressively relevant impact on fish farming, linked to a multitude of issues associated with fish welfare. Temperature affects the physiology of both fish and pathogens, and has the potential to lead to significant increases in disease outbreaks within aquaculture systems, resulting in severe financial impacts. Significant shifts in future temperature regimes are projected for the Mediterranean Sea. We therefore aim to review and discuss the existing knowledge relating to disease outbreaks in the context of climate change in Mediterranean finfish aquaculture. The objective is to describe the effects of temperature on the physiology of both fish and pathogens, and moreover to list and discuss the principal diseases of the three main fish species farmed in the Mediterranean, namely gilthead seabream (Sparus aurata), European seabass (Dicentrarchus labrax), and meagre (Argyrosomus regius). We will attempt to link the pathology of each disease to a specific temperature range, while discussing potential future disease threats associated with the available climate change trends for the Mediterranean Sea.

“…In contrast to the south of Norway, an increase in average sea surface temperature due to climate change could enhance salmon farm productivity in northern areas of this country (e.g., at Skrova), by enhancing salmon growth [ 62 ]. Still, geographic differences call for the importance of calibrating climate change projections to local conditions at farm sites, a key aspect to inform and develop farm-specific adaptation strategies [ 105 ].…”

Atlantic salmon (Salmo salar) cage farming has traditionally been located at higher latitudes where cold seawater temperatures favor this practice. However, these regions can be impacted by ocean warming and heat waves that push seawater temperature beyond the thermo-tolerance limits of this species. As more mass mortality events are reported every year due to abnormal sea temperatures, the Atlantic salmon cage aquaculture industry acknowledges the need to adapt to a changing ocean. This paper reviews adult Atlantic salmon thermal tolerance limits, as well as the deleterious eco-physiological consequences of heat stress, with emphasis on how it negatively affects sea cage aquaculture production cycles. Biotechnological solutions targeting the phenotypic plasticity of Atlantic salmon and its genetic diversity, particularly that of its southernmost populations at the limit of its natural zoogeographic distribution, are discussed. Some of these solutions include selective breeding programs, which may play a key role in this quest for a more thermo-tolerant strain of Atlantic salmon that may help the cage aquaculture industry to adapt to climate uncertainties more rapidly, without compromising profitability. Omics technologies and precision breeding, along with cryopreservation breakthroughs, are also part of the available toolbox that includes other solutions that can allow cage farmers to continue to produce Atlantic salmon in the warmer waters of the oceans of tomorrow.
