Citizen science records describe the distribution and migratory behaviour of a piscivorous predator, Pomatomus saltatrix

Understanding the processes driving species distributions is a key question in ecology, yet obtaining pertinent data for many species can be challenging. Tag-recapture data from voluntary recreational fisheries programmes is an undervalued citizen science data resource and can provide valuable observation records for data-poor species. Here, we highlight the utility of such data by compiling four tag-recapture datasets (n = 20 878 tags) to...
