Bakersfield Lake

October 21, 2021

Question: I saw photos online of a fish with odd looking teeth that was caught in a lake in Bakersfield. Some people thought it might be a piranha. Did the California Department of Fish and Wildlife (CDFW) look into this?

Answer: Yes, they were great photos, which made it easy to identify the fish as a pacu. Pacus are a popular tropical aquarium species that often outgrow their tanks and are unfortunately released by owners who no longer want them. Pacu and piranha can be differentiated by the shape of their mouth and teeth. When the mouth of a pacu is opened the gap between the upper and lower lip form a squarish gap, whereas on the piranha the upper and lower lip form a V-shape. And while pacu teeth may appear sharp, they are no comparison to those of piranha, which are as sharp as razors.

Winter cold water temperatures probably would have taken the fish out if the angler hadn’t. Based on their tropical water temperature requirements, we do not anticipate pacus, or piranha either, are capable of invading California waters.
