Abstract: Literature on small-scale fisheries usually depicts them as preferable over large-scale–industrial fisheries regarding societal benefits (jobs, jobs per investment) and relative fuel efficiency (e.g., Thomson 1980). We propose an environmentally extended Thomson table for comparing the Peruvian anchoveta (Engraulis ringens) fleets of purse seiners, backed up by methodological information and augmented with life cycle assessment (LCA)-based environmental performance information, as a more comprehensive device for comparing fleets competing for the same resource pool. Findings from LCA and a previous study on the anchoveta steel fleet together allowed characterizing the whole Peruvian anchoveta fishery. These results, along with socioeconomic indicators, are used to build an environmentally extended Thomson table of the fleet’s main segments: the steel industrial, the wooden industrial, and the wooden small- and medium-scale (SMS) fleets. In contrast with the world figure, the Peruvian SMS fleets show a fuel performance nearly two times worse than the industrial fleets, due to economies of scale of the latter (although the small-scale segment itself (
