Variations: Lodsilungur, Lod-silungur, Shaggy Trout; Loðufsi (Shaggy Pollock)
The Loðsilungur, or “Shaggy Trout”, is one of the most toxic fishes to inhabit Iceland. The earliest accounts date from the mid-17th century, where it is obliquely referred to as the “poisonous menace”. Illness and death follow the consumption of a loðsilungur.
The appearance of the Icelandic shaggy trout varies, but a trout-like shape and the presence of hair are diagnostic. Loðsilungurs tend to be ugly and strange. The one described in Nordri in 1855 had a beard of reddish hair on its lower jaw and neck as well as hairy patches on its sides and hairy fins. Another account distinguishes between trout with shaggy hair near the front of their head, and trout with hairy manes on either side. The adipose fin is either reduced or absent, and scales may not be present. The most detailed description specifies that it is no bigger than an Arctic char, and is often the size of a man’s finger. The tail is narrower and the front thicker than in other trout. The small, deep-set eyes are set ahead of a bulbous skull. The short snout has a distinctive overbite. The teeth are pitch black. Finally, the loðsilungur is covered with fine, downy, cottony-white hair. This hair, the namesake of the trout, resembles mold and is visible only when the fish is dead and in the water; on dry land it lies flat against the scales and becomes invisible. This makes it easier to confuse with edible trout – and makes it that much more deadly.
Across Iceland the tale is told of a tragic group poisoning. In 1692 the inhabitants of the farm called Gröf were found dead around a table with a cooked loðsilungur. Two brothers in a hunting lodge near Gunnarssonavatn Lake died with plates of trout on their knees. The most notorious poisoning incident is that of the Kaldrani farm, where an entire household were killed by a meal of loðsilungur. Only one young pauper girl had no appetite at the time, and avoided a terrible death.
Dogs and birds of prey, normally indiscriminate in their eating habits, will refuse to eat a loðsilungur. The shaggy trout are also tenacious and will cling stubbornly to life as long as possible. A group of fishermen in Hoffellsvatn Lake found that out the hard way; they left a catch of fish out overnight, only to find a live loðsilungur squirming on top of the pile. The entire catch was discarded and the lake abandoned.
