Lobón-Cerviá and Rincón analysed the dynamics of a stream-resident brown trout (Salmo trutta) population using stockrecruitment relationships, and reported no indication of density dependence but strong effects of water discharge on juvenile production. The authors concluded to have demonstrated an...
