Anglers at Laguna Niguel Lake have recently reported an unusual and troubling discovery — largemouth bass turning up with pink rubber bands wrapped tightly around their tails, breaking through their flesh and exposing an open wound. The sightings began after a recent fish die-off, when several regulars at the lake noticed healthy-looking bass, typically weighing between two and five pounds, bearing deep marks and injuries consistent with tightly applied rubber bands. In some cases, the bands had cut so far into the tail that tissue damage was severe, leaving fins nearly severed or scarred.
The pattern of the injuries suggests that the fish had been banded for some time. Many of the bass showed healed mouths, indicating they hadn’t been caught recently, and several of the rubber bands were partially embedded beneath the skin. The consistent color and placement of the bands imply that this was not a random accident involving debris or discarded gear but rather deliberate human interference.
Laguna Niguel Lake’s management team and AquaTechnex, the company responsible for monitoring the lake’s water quality, confirmed that no official tagging or marking program is underway. Supervising Park Ranger Adam Martinez stated that neither O.C. Parks nor AquaTechnex tags bass or other fish species at the lake. Both agencies have since contacted the California Department of Fish and Wildlife to investigate and assess potential impacts on fish welfare.
While the motive behind the banding remains unclear, some anglers speculate it could stem from a misunderstanding or an ill-informed attempt at fish tagging by an unofficial person. It’s possible that local anglers, or perhaps kids experimenting out of curiosity, are using rubber bands as a way to identify fish they’ve caught and released, perhaps to see if they can catch the same one again later. Others suggest it might have started as a casual game or “tag-and-catch” challenge among friends, unaware that such makeshift tags can cause serious harm as the fish grow.
Whatever the reason, those who may be tagging fish this way likely don’t realize how dangerous rubber bands can be for aquatic life. As a fish grows, a tight band can restrict blood flow, cut into tissue, and lead to lasting injury or death. While some might view it as a harmless experiment, it can have devastating effects on the health of the lake’s fish population.
Officials are urging visitors to remain vigilant and report any suspicious activity or signs of fish tampering. Anyone who encounters a fish showing signs of injury or unusual markings should contact Laguna Niguel Lake staff at (949) 923-2241 or call CALTIP at (888) 334-CALTIP.
