Distribution
• This fish is native to Lake Chad, and the Nile and Zaire Rivers in Africa.
• It was introduced to Lake Victoria in the 1950’s, where it can be found today in huge numbers.
Effects on People
• The Nile Perch provides food for locals. • This fish caused a decline of small fisheries and
an increase in large fishing operations• Increased fish exports=more money and jobs!
Effects on the Ecosystem
• Extinction of 200 species of cichlids
• Huge increase in algae levels, therefore, levels of oxygen in the Lake decreased.
• Increased # of insects
( prey of cichlids)
Position in Food Web
Changes to the Food Web
• Decline in fish eaten by the Nile Perch such as catfish and lungfish.
• Increase in algae causing death of small animals and plant life.
So Successful!
• No known predators living in Lake Victoria.
• Reproduce in large numbers. A female can produce up to 16 million eggs at one time!!!!
The Future of the Nile Perch
• Population may decline due to inadequate food supply and overfishing.
The Nile Perch
• I hope you learned more about an invasive species and how it can impact the ecosystem in which it now lives.
