The Nile Perch is a large freshwater fish, measuring up to 2m in length. He is native to parts of Africa, and has been introduced to other other parts. A voracious and fierce predator, he feeds on small fish, including his own species. When this species was introduced to Lake Victoria, it proved an ecological disaster, devouring the native cichlids before moving onto smaller prey. The establishment of large fishing industries also affected the local human populations and has caused further environmental damage.
