History
A Mörrum fly whose name is Swedish for "the wool sock". Its origins are unclear: Ahrex's video notes credit Alf Jansson in the 1960s and name the old Irish shrimp flies as its model, while Viking Lars dates it to the 1950s and says nobody knows who first tied it. Jan Grünwald recalls it as one of the two flies that took most of the Mörrum's May and June salmon in the early 1980s. Viking Lars gives the original as a red wool butt, black wool bodies and stiff brown cock hackles, with no tail. Newer dressings from Mörrum add a red rear hackle and red flash, and Ahrex's notes suggest doubles, trebles and tubes as the ones to carry.
Fishing it
Fished like any wet fly for salmon, across and down. Viking Lars catches late-summer and autumn salmon on it in Danish rivers, deep on a sinking shooting head. He prefers stiff cock hackles, which he thinks push water and vibrate rather than lie back in the current.
