Geographic variation of Sebastes mentella in the Northeast Arctic derived from a morphometric approach
11 pages, 9 figures, 5 tables. At present there is considered to be only one management unit of Sebastes mentella in the Northeast Arctic. A morphometric analysis was conducted to compare specimens from different locations and different times of the year. Residuals of the regression between each mor...
