Purpose Fisheries represent a globally significant commercial sector whilst rising demand for fish products has intensified environmental emissions. Despite increasing fish consumption, fisheries have stagnated over the past three decades due to their reliance on wild fish stocks, limiting the potential for increased production. In Life Cycle Assessment, these constraints are often overlooked, not capturing the complexities un...

Results from life cycle assessment (LCA) studies are sensitive to modeling choices and data used in building the underlying model. This is also relevant for the case of fisheries and LCAs of fish products. Fisheries' product systems show both multifunctionality because of the simultaneous co‐catch of multiple species and potential constraints to supply due to natural stock limits or socially established limits such as quota sy...
