Population structure of Sebastes mentella in the north-east Arctic
18 páginas, 5 tablas, 9 figuras At Present time it is considered the existence of only one management unit of S. mentella in Northest Atlantic. In present paper a morphometric analysis is made to compare specimens from different time of the year. Residuals of the regression between each morphometric...
