Review of the Freshwater Cuskfishes of Iran (Family Lotidae)

The systematics, morphology, distribution, biology, economic importance and conservation of the burbot (Lota lota) of Iran are described, the species is illustrated, and a bibliography on this fish is provided. The chin barbel and two dorsal fins, both lacking spines, are distinctive characteristics of this fish. This species favours well-oxygenated, cool, clear rivers and large, deep lakes where it is most active at night or at twilight (crepuscular). Lota lota species is found rarely in the Caspian Sea basin.
