“…Usage of RAS waters for plant production helps Fulfilling the increasing global food demand requires sustainable food production systems. Aquaponic systems (Baganz et al, 2021) are a possibility to increase the sustainability of fish production by addressing some of the challenges of conventional aquaculture, for example, contribution to climate change, environmental pollution, excessive water consumption, soil-sealing, and degradation (review by Cao et al, 2007;Costa-Pierce et al, 2010;Lucas et al, 2021). Recirculating aquaculture systems (RAS) produce water, which commonly has elevated concentrations of dissolved nutrients, especially nitrogen (N) and phosphorous (P), which can be a problem for freshwater ecosystems due to their eutrophication-inducing effect (Cao et al, 2007).…”

Societal Impact StatementRefining circular multitrophic food production methods, which integrate plant, fish, and insect outputs, is imperative for environmental sustainability. Our findings suggest that the right protein choices in fish feed, like black soldier fly meal and poultry meal, can notably enhance the nutrient profile of fish waste water. This, in turn, is conducive for hydroponic cultivation, enhancing the nutritional attributes of plants like basil and lettuce. As we reduce environmental impact and optimize resource use, it is evident that our food ecosystems are deeply intertwined. Harnessing these synergies could redefine our approach to food production, paving the way for a more sustainable global future.Summary Optimization of nutrient use efficiencies in circular multitrophic food production systems (i.e., plant, fish, and insect production) is crucial for sustainability. This study tested how protein ingredient choice in fish feed influences the plant nutritional value of the fish waste water when used for hydroponic crop production. Waste water samples were obtained from recirculating aquaculture systems (RAS) in which Nile tilapia (Oreochromis niloticus) were fed different single protein source diets—black soldier fly meal (BSFM), poultry by‐product meal (PM), poultry blood meal (PBM), and fish meal. Water was analyzed for plant nutrients and used for lettuce and basil cultivation to evaluate their suitability for hydroponic crop production—viz. yield, mineral nutrient, and selected secondary metabolite levels. BSFM RAS water had the highest concentrations of K, Mg, and micronutrients (Cu, Mn, Mo, Zn) of the RAS waters, whereas PM RAS water contained the highest P concentration and had a mean pH of 6.5 closer to the optimum pH for hydroponic plants. These RAS waters consequently lead to the highest yields in basil and lettuce indicating the importance of the aforementioned factors. From a plant production perspective, BSFM appears promising as a protein source in fish feeds for aquaponics. Usage of RAS waters for plant production helps reduce (i) environmental impact of RAS water and (ii) resource input in plant production. Longer term RAS trials should be conducted to determine the maximum nutrient concentrations achievable during fish production with diets including BSFM as the main protein source.

“…Each level up the trophic chain decreases the efficiency of utilizing energy produced by photosynthetic organisms. For this reason, metrics calculated with the trophic level are often used as indicators for sustainability [19,20]. Though the original meaning of TL has been blurred recently with the increasing share of vegetablebased ingredients in diets of farmed carnivorous species [21], the protein content (either it is sourced from vegetable or animal ingredients) and cost of aquafeed recipes are still higher for carnivorous species than for herbivores.…”

Freshwater Aquaculture Development in EU and Latin-America: Insight on Production Trends and Resource Endowments

2022

View full text Add to dashboard Cite

This paper provides a comparative overview of decadal changes in aquaculture production in the European Union (EU-27) and Latin America and the Caribbean (LAC). Contrary to other regions of the world, freshwater fish farming in these two territories is a marginal sub-segment of the aquaculture sector. Using an indicator-based approach, we track development tendencies in freshwater aquaculture, focusing on the main established and emerging species, diversification, and shifts in the mean trophic level of farmed animals. Geographical patterns in production trends are revealed in both regions. The study attempts to explain between-region and between-country differences in aquaculture growth by analyzing freshwater resource endowments at region-level and country-level, using total renewable water resources (TRWR) as an indicator of water-abundancy. Thermal optimum of main produced species is matched against climate conditions prevailing in main producer countries to provide further understanding of spatial heterogeneity in growth rates of aquaculture sector.

“…Although fish production is highly dependent on fish gear, it directly affects the marine ecosystem as it limits resources and occasionally disturbs the seabed. Indirect pressure is posed by the aquaculture of carnivorous species [23,24]. To an extent, waste production by aquaculture activities increases as well.…”

“…Moreover, the asked quantity for wood is volumetric, so a radius of 10 cm was assumed to calculate the volume of wood used; • Fleet: In the traditional fish-catching facilities, the use of a boat is necessary to approach the traps and collect the captured fish. According to the literature, a wooden boat with a length of 6.5 m and a width of 1.5 m weighs 1000 kg [23], whereas the boats used in Klisova Lagoon have a length of 5 m and a width of 1.5 m [73]. Thus, based on the length-to-weight ratio of the "gaita," its weight is assumed to be 700 kg.…”

Food systems account for one third of greenhouse gas emissions while fish production is assigned 4% of total anthropogenic emissions as well as other environmental implications. The Greek fishery industry is a very promising and upcoming sector with renowned products such as “Avgotaracho Mesolongiou”, the Greek bottarga, which is a product of designated origin (PDO) with cultural and economic significance but unexplored environmental impacts. The aim of the study is to depict the environmental hot-spots of “Avgotaracho Mesolongiou” production using the life cycle analysis (LCA) methodology with the help of SimaPro v3.5 software and the Ecoinvent database v3.9. “Avgotaracho Mesolongiou” supply chain is divided into the fish extraction, roe processing and transport, and retail stages, while the inventory of each stage is filled with data depicted from producers via a questionnaire and findings from the literature. The hot-spot analysis of Avgotaracho Mesolongiou exhibited high human carcinogenic toxicity, and marine and freshwater ecotoxicity impacts that account for more than 90% of total normalized scores. More specifically, the use of metallic traps in the fish-catching facilities presented the highest contribution among the inputs and was responsible for more than 70% of total normalized scores. Furthermore, the uncontrolled treatment processes of waste streams are attributed 6% of total normalized scores. More specifically, waste wood open-burning accounts for 10% of human carcinogenic toxicity while disposal of wastewater was responsible for 25% of freshwater eutrophication. Moreover, a scenario-driven LCA was conducted to compare the existing waste treatment meth+ods to a proposed improved waste management (IWM) scenario. The implementation of controlled treatment processes resulted in a decrease in human carcinogenic toxicity and freshwater eutrophication impact by 8% and 26%, respectively. The outcome was proven to be robust in respect to the affected impact categories while the fish extraction remains the most impactful stage of the supply chain when subjected to a sensitivity analysis.
