Abstract
Effective management of aquatic resources, wild and farmed, has implications for the
livelihoods of dependent communities, food security, and ecosystem health. Good
management requires information on the status of harvested species, yet many gaps
remain in our understanding of these species and systems, in particular the lack of
taxonomic resolution of harvested species. To assess these gaps we compared the
occurrence of landed species (freshwater and marine) from the United Nations Food
and Agriculture Organization (FAO) global fisheries production database to those in the
International Union for Conservation of Nature (IUCN) Red List and the RAM Legacy
Stock Assessment Database, some of the largest and most comprehensive global
datasets of consumed aquatic species. We also quantified the level of resolution and
trends in taxonomic reporting for all landed taxa in the FAO database. Of the 1,695
consumed aquatic species or groups in the FAO database considered in this analysis,
a large portion (35%) are missing from both of the other two global datasets, either
IUCN or RAM, used to monitor, manage, and protect aquatic resources. Only a small
number of all fished taxa reported in FAO data (150 out of 1,695; 9%) have both
a stock assessment in RAM and a conservation assessment in IUCN. Furthermore,
40% of wild caught landings are not reported to the species level, limiting our ability
to effectively account for the environmental impacts of wild harvest. Landings of
invertebrates (44%) and landings in Asia (>75%) accounted for the majority of harvest
without species specific information in 2018. Assessing the overlap of species which are
both farmed and fished to broadly map possible interactions – which can help or hinder
wild populations - we found 296 species, accounting for 12% of total wild landings
globally, and 103 countries and territories that have overlap in the species caught in the
wild and produced through aquaculture. In all, our work highlights that while fisheries
management is improving in many areas there remain key gaps in data resolution that
are critical for fisheries assessments and conservation of aquatic systems into the future.
