Problems with combining modelling and social science approaches to understand artisanal fisheries bycatch

Aim: Artisanal fisheries account for 40% of the world’s fisheries catch, yet its environmental impacts remain poorly understood. This is especially the case in developing countries. In this study, we sought to integrate Local Fisher’s Knowledge with distribution modelling to estimate the annual bycatch of Titicaca Grebe (Rollandia microptera), an endangered endemic bird from Lake Titicaca whose main anthropogenic threat is bycatch.
Location: Lake Titicaca, Peru & Bolivia
Methods: We conducted transect and point counts of fishing nets in March – September, 2022, and conducted interviews with fishers across the Lake Titicaca region. Using bathymetry, distance from shore, distance from a settlement, distance from the protected area, presence/absence of aquaculture, distance from aquaculture, and wetland cover, we constructed a distribution model of fisheries using maximum entropy modelling. We conducted interviews with fishers asking about the frequency of grebe bycatch, and conducted ..., , , # Data from: Problems with combining modelling and social science approaches to understand artisanal fisheries bycatch

To comply with Dryad policies regarding endangered species, the locations of the nets have been rounded, though non-rounded net values are available upon request for legitimate scientific purposes.
