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.

3. 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!

4. 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)

5. Position in Food Web

6. 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.

7. 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!!!!

8. The Future of the Nile Perch
Population may decline due to inadequate food supply and overfishing.
