Short description Morfologi | Morfometri

Biologi     Ordlista (t.ex. epibenthic)

Migratory species, which breeds in the ocean (Ref. 52331). Inhabits both quiet and fast flowing water (Ref. 13337). Elvers ascend rivers mainly at night and overcome waterfalls and walls of dams with great determination. Adults usually sedentary. Females can attain 120 cm SL and are generally longer and heavier than males (Ref. 48660). Carnivorous, eats dead or living prey but especially fish and crabs. After feeding in fresh water for ten years or more, adults assume a silver breeding dress, the eyes become enlarged and they return to sea to breed. Considered to breed east of Madagascar, but thought to move south of that island on its way to the Mozambique coast and South African rivers (Ref. 13337). Flesh fatty but highly esteemed as smoked or jellied eel (Ref. 5214). Caught with various types of nets (Ref. 4967).
