ARVADA, COLORADO — In a concerted effort to protect local ecosystems, Colorado Parks and Wildlife (CPW) successfully removed 14 invasive bighead Carp from the Jack B. Tomlinson Park in Arvada this Wednesday. The intervention was triggered by a public tip, leading CPW aquatic biologists to act swiftly, using advanced electrofishing techniques to capture the oversized fish.
Bighead carp, a type of Asian carp, are known for their detrimental effects on native habitats. These fish compete aggressively with local species for food, mainly consuming plankton, which many native and sport fish also rely on. “Bighead carp can dominate the local fish population due to their size and feeding habits,” explained Robert Walters, CPW’s Invasive Species Program Manager. “Their presence can lead to a significant imbalance in the aquatic ecosystem.”
Originating from a 1992 study aimed at controlling algal blooms, these carp were supposed to be removed by 1995. However, they have continued to thrive, posing ongoing challenges for conservation efforts. “The fish’s large size suggests they have not been reproducing naturally here, which is fortunate,” noted Kyle Battige, CPW’s senior aquatic biologist for the northeast region. “This means our quick response could effectively curb their impact.”

CPW officials emphasized the importance of community involvement in detecting and reporting invasive species. “This operation began with a crucial tip from a concerned angler,” said Philip Sorensen, CPW District Wildlife Manager for Westminster and Arvada. “Such community reports are invaluable in our efforts to maintain the health of our waterways.”
The CPW plans to continue monitoring the area and other potential habitats to prevent the carp from re-establishing themselves. They urge anyone who spots unusual aquatic species to report these sightings to state wildlife authorities promptly.
