“…mass, economic, energy; given that the system boundaries were limited to the landing of fish at port, mass allocation was selected as the most appropriate approach (Laso et al, 2017b). The reason is that, following the PEFCR, mass allocation is considered to better reflect reality over longer periods and changing economic conditions, such as those during the pandemic and crisis, apart from not being highly affected by the volatile economic price of the product, which depends on the season, freshness and many other market factors (Laso et al, 2022). In addition, this approach provides a clearer perspective for communicating results to stakeholders at this early stage of the supply chain (Laso et al, 2018b) and facilitates to contrast outcomes with other similar fisheries studies, in which the use of 1 kg of fish as a functional unit is the most established.…”
