Lake Michigan, one of the Great Lakes, has been home to a surprising and unusual fish species: the Pacu, known for its human-like teeth. The Pacu, a relative of the piranha, is native to the Amazon River and other freshwater sources in South America. Despite being an exotic species, it has been found in Michigan waters, particularly in Lake St. Clair and the Port Huron area.
What Type of Fish with Human-Like Teeth Can Be Found in Lake Michigan?
The fish with human-like teeth found in Lake Michigan is the Pacu (Piaractus brachypomus). This species is known for its flat, dull teeth, which are used primarily for eating nuts, seeds, and fruits. Pacus are omnivorous and can grow up to 3 feet long and weigh up to 55 pounds.
Are Fish with Human-Like Teeth Native to Lake Michigan?
No, fish with human-like teeth are not native to Lake Michigan. The Pacu is native to the Amazon River and other freshwater sources in South America. They have been introduced to Michigan waters through the aquarium trade, where they are popular pets. However, when they outgrow their aquariums, owners often release them into nearby lakes and rivers, leading to their presence in non-native environments.
Can I Catch Fish with Human-Like Teeth While Fishing in Lake Michigan?
Yes, it is possible to catch Pacus while fishing in Lake Michigan. Anglers have reported catching Pacus in Lake St. Clair and the Port Huron area. However, it is essential to note that releasing non-native fish into Michigan waterways is illegal and can lead to ecological disruptions. If you catch a Pacu, it is recommended to keep it and preserve it on ice or take photos of it. Do not return it to the water. Contact the Michigan Department of Natural Resources for assistance in identification.
