Oklahoma City Fisheries Management personnel were in for a surprise during their routine electro-fishing survey at Zoo Lake this week, when they reeled in a colorful interloper weighing 14 pounds. The unexpected visitor was a koi fish, a species not native to these waters. The team from Oklahoma City, accustomed to managing the aquatic health of the ecosystem, promptly removed the fish to prevent any possible disruption to the local population, as reported by News 9.
The koi, known to feast on the eggs of other fish, was discovered at a beloved local spot for anglers, raising questions about its origins. "Running bet is that it either came in a fisherman’s bait bucket, or someone just had a big fish they didn’t want to keep around," fisheries biologist John Rayfield said in an interview obtained by KCTV5. This interjection of a non-native organism flares concerns regarding the balance and integrity of the pond's indigenous fish community.
Employing electrofishing - a conservation technique aimed at stock assessment that temporarily stuns fish for study and measurement - the biologists stumbled upon the koi, described as quite the specimen. "We have a nice, big generator on a boat with these antennas that go into the water, and we actually shock the fish, and they come to the surface and then we weigh and measure them and release them back into the water," Rayfield explained in a statement obtained by KOCO. Upon the unexpected capture, the decision was made to transfer the koi from the lake to a new habitat more suited to its needs.
The new domicile of the koi is Will Rogers Gardens, where it has joined other fish in an environment safe from the pressures of sport fishing and the potential for ecological disturbance. Though not labeled as invasive, the relocation was deemed necessary for the koi's well-being as well as for the preservation of the local pond's ecological health. Rayfield has noted a continued vigilance against unexpected aquatic guests, revealing that "there is a goldfish at Martin Nature Park that we are trying to catch, but he has eluded us for a few years," according to a KOCO interview.
On Saturday, the public will have an opportunity to gain insight into Oklahoma City's efforts to sustain its aquatic ecosystems. An open house is scheduled from 11 a.m. to 2 p.m. at HB Parsons Fish Hatchery, showcasing their fishery program which is touted as one of the most robust in the nation. The public can also view the 14-pound koi among its new company, readily observable in its non-fishing pond environment.
