Labeo coubie , engl. African Carp, is a carp fish from Africa . It is the most common specieswithin the Labeo genus.
Occurrence
Labeo coubie is widespread in tropical Africa between latitudes 6 ° N – 6 ° S. She lives from Senegal to Ethiopia . The species occurs in the river system of the Nile (also Blue Nile , Albertsee ) down to the lower reaches of the river in Egypt , mainly in West Africa in Chad , in the Niger , Benin River, in the Volta , Gambia River , the rivers of Senegal , the Cross River and various Coastal rivers of Cameroon . Furthermore, the species occurs in East Africa and in the middle reaches of the Congo from Stanley Pool to Kisangani . It is also suspected in the Zambezi , but this has not been confirmed.
description
Labeo coubie is 75 centimeters long on average and weighs five kilograms. The largest fish caught weighed seven kilograms and was 80 centimeters long, and was caught in Cameroon in 2004. Labeo coubie lives mainly in rivers. The fish has the following fin formula: dorsal 11–13, anal 8 and 31–33. The outer lip has a fold. There are small barbels in the corner of its mouth . The barbels recede with age. The body is mostly dark. The back and sides are colored blue-gray or black-violet, sometimes also silvery, the underside of the abdomen is lighter. Some of the scales have a purple or red-purple center and are more bluish to black on the outside.
Way of life
Labeo coubie shows a benthopelagic way of life and migratory behavior at spawning time. The fish live mainly in rivers or in sheltered bays in lakes. They mainly look for food on the bottom of the water and feed on dead organic material, plant remains and algae. The spawning season is from spring to summer.
Hazardous situation
Labeo coubie is considered widespread in Central and West Africa and is not currently endangered. Due to a lack of data on species distribution, population size and threats, the species in East and Northeast Africa was classified as a “data deficient”. It is considered to be threatened in northern Africa. Their stocks are threatened by high fishing pressure, water pollution (agricultural biocides, domestic and industrial wastewater), the construction of dams, lowering of the groundwater level and drought.
Economical meaning
Labeo coubie is an important food fish , especially in West Africa, and is kept in ponds. The fish is known for its slightly sweet taste with a nutritious protein pattern. The month of catch and the quality of the meat vary over the year.
