What is an introduced species?
• A species that has been moved by
humans from its normal habitat to a new
habitat, either intentionally or by a mistake
• Also often referred to as invasive species
Example of Introduced Species:
Nile Perch
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
