“…Fish in the poorest physical condition show the greatest response, displaying immediate mortality or by rapid rates of weight gain when adequate rearing conditions are restored (Jobling ). Experiments with Atlantic cod (Luczkovich & Stellwag ; Imsland, Foss, Folkvord, Stefansson & Jonassen ; Badiola, Albaum, Curtin, Gartzia & Mendiola ) and halibut (Larsen, Imsland, Lohne, Pittman & Foss ) have shown that an early drop in water temperature could lead to long‐term effects of increased growth, which is a to benefit in commercial aquaculture, although some authors discouraging this practice and further investigations would be required to prove such advantages.…”

Land-based growth of Atlantic salmon (Salmo salar) and consumers’ acceptance

et al. 2017

Atlantic salmon (Salmo salar) is currently the highest valued species grown in Europe. The industry has been on the frontline of public concerns regarding sustainability which has increased the use of recirculating aquaculture systems (RAS). Salmon has changed from a luxury product to global commodity. Nevertheless, food products need to meet consumers demand for the industry to be successful. Descriptive sensory tests present a sophisticated tool for the comparison of product prototypes to understand consumer responses in relation to sensory attributes. Aquaculture is being promoted in the Basque region with the aim of creating a sustainable and complementary economic activity to the fishing and seafood sectors. Here, RAS and salmon have been prioritized as a potential technology and species respectively. Both salmon's growth and a hedonic evaluation of the final product's consumer acceptance and purchasing intention were studied. One thousand five hundred salmon individuals were grown for 497 days at two different thermal regimes in two pilot-scale RAS units using partial reuse water recirculation systems. Growth rates were significantly different for both temperature regimes during the second summer season; some compensatory growth patterns were observed that followed the timing of the natural thermal regime. No significant differences were observed at sensorial level between fillet samples from the present study and salmon from Denmark. Consumer's high level of acceptance and positive product purchasing intention reflect the possibility of locally marketing RAS grown salmon. This study refers to the first technical attempt at salmon in land-based aquaculture systems in northern Spain.

“…A few authors have identified some promising species to be developed in offshore aquaculture as some of them are native and are economically interesting. Among them are fish such as the meagre Argyrosomus regius [32], cod Gadus morhua [33], salmon Salmo salar [34], gilthead sea bream Sparus aurata [35], sea bass Dicentrarchus labrax [36], sardine Sardina pilchardus [37], and greater amberjack Seriola dumerili [38]; mollusks bivalves such as mussel Mytilus edulis [39], scallop Pecten maximus [40], oyster Magallana gigas [41], and clam Ruditapes decussatus [42]; or even macroalgae as Gracilaria gracilis [43], Porphyra umbilicalis [44], and Undaria pinnatifida [45]. A survey of indexed papers in Scopus (published between 1975 and 2021) was carried out with the aim of compiling the optimal growth parameters for these species that can have the potential to be produced in aquaculture offshore or in coastal areas in Portugal.…”

Potential for Coastal and Offshore Aquaculture in Portugal: Insights from Physico-Chemical and Oceanographic Conditions

et al. 2022

Physico-chemical and biological parameters along the Portuguese coast were analyzed to evaluate the potential to produce aquatic species of economic interest. Water samples were collected in 2018 and 2019 in five different areas of the Portuguese coast. Currents data were collected between 2018 and 2020 and historical waves height data from 1988 to 2019. According to the results, there is a wide variety of species that can be considered for production. The northernmost area presented the lowest temperature, as well as the highest levels of chlorophyll a, and nitrate. Under such conditions, the rearing of salmon Salmo salar, mussel Mytilus edulis, scallop Pecten maximus, macroalgae Porphyra umbilicalis, and Undaria pinnatifida can be considered. Regarding the southernmost area, due to the highest temperature, this area seems appropriate for the production of meager Argyrosomus regius, sea bream Sparus aurata, sea bass Dicentrarchus labrax, and greater amberjack Seriola dumerili. This study highlights the challenges in deploying aquaculture structures on the Atlantic coast due to its oceanographic conditions. Site selection for aquaculture is a complex process and pilot studies are essential to analyze the feasibility of developing offshore aquaculture along the coast of Portugal.

“…In intensive pond production, feed tends to be the greatest cost followed by capital, fingerlings, energy, and labor/management. For RAS, capital costs are the greatest cost, followed by labor/management, and energy (Badiola et al, 2017). Costs of marine finfish farming are greater than those of freshwater fish because costs of broodstock acquisition, specialized feeds required for early life stages, hatchery labor skills, and feed costs are greater for marine than for freshwater fish.…”

Increased interest in marine fish farming in the United States has led to a need for fundamental economic information on production of candidate species for commercialization in various production systems. Funding for the project targeted those species with potential for production in southern tier states in the United States. Sufficient technical data were found to develop comprehensive budget analyses to estimate growout production costs for four scales of production for each of 10 species with potential for production in ponds, 13 in recirculating aquaculture systems (RAS), and five in net pens. The choice of species/production system scenarios was based on evidence of successful production on farms or in research. Estimation of production costs with enterprise budgets can provide useful guidance to identify the types of improved efficiencies that have the greatest effect on economic viability even when commercial farm data are not available. Commercial farm data were used where available, but for most species, data were available only from studies conducted under research conditions. Per‐kg costs of production were lowest for net pen production, followed by ponds, with production costs in RAS two to five times greater than in ponds or net pens. Ponds and net pens generally exhibited greater efficiency of use of capital assets across species than did RAS that resulted in lower percentages of fixed costs and lower annual costs per kg of fish produced. All five species evaluated for net pen production were estimated to be profitable, including redfish, Sciaenops ocellatus (also known as red drum), striped bass, Morone saxatilis, cobia, Rachycentron canadum, red snapper, Lutjanus campechanus, and seriolids (generic budget for almaco jack, Seriola rivoliana, California yellowtail, Seriola lalandi, and greater amberjack, Seriola dumerili), four in ponds (redfish, hybrid drum, ♀Pogonias cromis × ♂Sciaenops ocellatus, black sea bass, Centropristis striata, and cobia), but none of the RAS scenarios showed profitability at average yields (kg/cubic meter) reported in the literature. Comprehensive data on growout production of marine finfish species in the United States is generally lacking, and there is a strong need for production trials conducted under near‐commercial conditions with an endpoint of market‐sized fish. Production trials should be conducted in ponds (≥0.1 ha), net pens, and RAS tanks of a size that simulate commercial production conditions. Adequate production trial databases would provide opportunities to develop economic optimization models that would provide useful guidance for prospective producers. Average yields (kg/cubic meter) in RAS will need to be much greater than currently reported in the research literature for RAS production to be economically sustainable. Net pen production appears to be profitable in the United States, but effective permitting procedures are not in place. Providing research support for the US redfish sector that has developed effective production and marketing models could serve as a foundation for developing additional species and offer opportunities for diversification on marine finfish farms.
