Rednose labeo (Labeo altivelis) fish species information

Scientific Name
Labeo altivelis

Common Name
Rednose labeo

Biology
Prefers large rivers but is also found in large lakes and dams. Grazes on algae and `aufwuchs' from rocks (Ref. 7248). From October to December in Lake Mo?ro, the adults gather and migrate to the spawning grounds. They go up the Luapula River up to the foot of Johnston Falls where they undergo one massive spawning between January and March. This massive spawning of short duration is known as kapata in the Luapula-Mo?ro system and in the tributaries of the Luapula. This species is intensely fished and caviar is produce from eggs collected during migration from Lake Mo?ro to Luapula River (Ref. 26190).
