The timing of the smolt run in the Dale River in western Norway was monitored from 2002 to 2007 after annual stocking in late autumn 2000 to 2005 with 5000–10800, 11–16 g, Atlantic salmon, Salmo salar L., parr. The releases yielded an annual smolt production of 1000–2000 individuals, mainly 1+ smolts. Almost 5700 stocked smolts were trapped during smolt migration and 60% of these were genotyped for family identification. The d...

Fixed nucleotide differences were found in the partial 16S rRNA mitochondrial gene sequences between two regional populations of Maurolicus (identified as M. muelleri and M. walvisensis ), indicating clear genealogical separation of the two taxa. Accordingly, the two taxa can be considered as recently diverged species, supporting the recent proposition of a polytypic genus Maurolicus .
