“…1). The recent reports highlight the importance of reduction of distances between feed production and usage sites, employment of feed production facilities in aquaculture sites, and selection of locally available feed ingredients in diet formulations to reduce transportation emission or preference for lowcarbon-emission feedstuffs in diets to mitigate the environmental impact of aquaculture (HatcheryFeedManagement 2021;HatcheryInternationalStaff 2021;da Silva Pires et al 2022). Likewise, our results support the need to decrease CFCD and CFT associated with diet and transport in CPRT farming systems.…”

The carbon footprint (CF) of animal production systems can estimate their standings against global protein demand. Turkey is the top rainbow trout producer in Europe, but surprisingly little is known about the CF of the production. This study aimed to evaluate the CF expended of concrete pond rainbow trout (CPRT) farming. The data were obtained from a farm with an annual project production capacity of 350 tonnes (APC) over a three-year production (TPY) with different harvest amounts. Total CF expended was the summation of CF expended on compound diets, general management, transportation and machinery, equipment, and construction. The total CF expended was calculated at 1.78 and 1.67 kg CO2e (equivalent) on average for TYP and APC, respectively. The TYP average values of CF expended per kg of protein deposited in harvested fish and CF expended per Mcal of cultural energy expended during production were 10.66 and 0.36 kg CO2e, respectively. The CF expended per 100 kcal food energy in harvested fish was calculated at 0.1263 and 0.1173 kg CO2e on average for TYP and APC, respectively. Aquafeed production and transportation are the important CF expended sources in CPRT. Future studies on CF expended of aquaculture farms must be species-specific and culture-specific.

“…In addition, considering the report of Boissy et al (2011), which states that depending on the diet content, the climate change effect (kg CO2e) of a plant-based diet in trout feed is 6% lower than that of a fish meal-based standard diet, it can be concluded that the CF of diets can be improved in trout aquaculture. At the same time, it has been reported that the choice of different feed production systems and feed ingredients considering the distance effect should be evaluated in terms of environmental impact strategies to create the less global warming effect of aquaculture feeds (da Silva Pires et al, 2022). Although these approaches reveal the importance of plant-derived feed ingredients for the sustainability of trout diets, attention should be paid to the kg CO2e unit -1 values of feed ingredients given in Table 3 in compound diet rations.…”

The purpose of this study was to assess the consumed compound diet and juvenile fish, harvested fish, and compound diet transport of Karacaören Dam Lake-I rainbow trout cage farming (KRTC) in terms of cultural energy (CE) and carbon footprint (CF) expended sustainability. Data was collected through face-to-face interviews with the farmers. Cultural energy and carbon footprint were calculated with the data obtained from the literature. The lowest and highest FCRs in KRTC were 0.91 and 1.18, the closest and farthest distances related to transportation were 387 and 427 km for aquafeed factories, 7 and 650 km for hatcheries, and 67 and 450 km for processing factories. Cultural energy and carbon footprint expended on consumed compound diet (CECD-Gcal and Mcal kg-1, and CFCD-tonne CO2e and kg CO2e kg-1) and cultural energy and carbon footprint expended on transportation analyzes (CET-Gcal and Mcal kg-1, and CFT-tonne CO2e and kg CO2e kg-1) were performed according to the literature of 20-40 g fish stocked in the beginning of November 2020 and 270-500 g harvested until early June 2021 in the basin. In the access of sustainability, the CE (Mcal kg-1) and CF (CO2e kg-1) expended values in kg of the harvested fish were given. The average values of CE expended of 5 different aquafeed groups used in the basin were 3.65, 3.58, 3.41, 3.25, and 3.55 Mcal kg-1, respectively and the average values of CF expended were 1.05, 1.03, 1.14, 1.40, and 1.10 kg CO2e kg-1, respectively. The average share of CE and CF in the compound diet was 86.59% and 86.61%, respectively. The KRTC sustainability criterion for compound diet and transportation values was 2.9260 CE:CF. It is recommended to develop a sustainability index of aquaculture systems and species-specific CE and CF expended values.
