Nile Perch Notes
Name of organism Lake Victoria perch (formerly Nile Perch)
Lates niloticus
Order – Perciformes
Class – Osteichthyes (boney fish)
Phylum – Chordata
Kingdom - Animalia
Distribution Native to Lake Chad, Nile River, Zaire River, and Niger River
Introduced to Lake Victoria in the 1950s
Now present in huge numbers throughout Lake Victoria
Effects on people Huge increase in food availability for locals
Decline in smaller fisheries and increase in large fishing operations
Increase in fish exports, providing more money and jobs
Effects on ecosystems Extinction of 200 species of cichlids
Four-fold increase in algae levels, which has reduced oxygen availability in the lake
Increase in the number of insects (prey for cichlids)
Deforestation (wood needed to process Nile Perch)
Position in the food web Predator of small fish such as cichlids
Nile Perch’s only predator are people
Reasons for success No natural predators in Lake Victoria
Large, powerful fish – easily caches fish and shrimp native to Lake Victoria
Issues in the future Governments and many local people do not wish to remove Nile Perch
Population of Nile Perch may change depending on its food availability
