Report of the Study Group on Stock Identity and Management Units of Redfishes (SGSIMUR)

The Study Group on Stock Identity and Management Units of Redfishes [SGSIMUR] has reviewed all reported

material on the stock identity of the various redfish units (S. mentella) in the Irminger Sea and adjacent waters, and

identified the most likely definition of biological stocks of S. mentella as well as suggested practical management units.

The review did especially focus on the reported material relevant for the Terms of Reference, i.e. material on

differences in reproductive cycle, spawning areas, drift of larvae, nursery areas and recruitment paths to the fishable stock(s), morphology, parasitology, otolith structure and trace element analysis, age- and growth differences, fatty acid profiles, genetic results, geographical distribution and behaviour (horizontal and vertical) of the fishery and from the scientific surveys.
