Piranhas were introduced into the United States primarily through the aquarium trade in the 1970s and 1980s, when they gained popularity as exotic pets due to their unusual appearance and predatory reputation. Some were released into the wild by owners who could no longer care for them or who were afraid of their aggressive nature. Additionally, accidental escapes from fish farms and aquaculture facilities contributed to their establishment in certain regions, particularly in Florida. These introductions have raised concerns about their potential impact on local ecosystems.
