Table 1 Summary of brown trout trap sampling and genotyping, both for sea trout ascending the Guddal River in 2006–2016 and for the smolts emigrating to sea in 2017

  1. Catches in the trap: total number of ascending fish caught in the trap. * including individuals with too many loci missing after genotyping. Trout individuals genotyped: total number of individuals minus fish with no samples, fish identified as Atlantic salmon and sea trout individuals caught several times within the same year in the ascending trap for adults. Two individuals were caught twice in 2008, two twice in 2011, one individual three times in 2012, one twice in 2014, one twice in 2015 and one twice in 2016
