The biggest haul came in 2025, when crews pulled out 36,863 pounds, which is about 18 U.S. tons.<\/p>\n\n\n\n<p>That is a lot of fish, but is it enough to change <a href=\"https:\/\/www.ecoticias.com\/en\/the-war-against-invasive-plants-that-devour-rivers-and-fields-enters-creative-mode-british-scientists-are-releasing-living-allies-that-no-one-would-have-imagined-in-a-modern-scientific-plan\/27828\/\">a river\u2019s trajectory<\/a>? If removals keep pressure on carp, native species can reclaim food and space, and boaters face fewer of those startling silver carp jumps near a motor. Still, the river is not a lab tank, so progress has to be measured carefully and over time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A record year on a busy river<\/h2>\n\n\n\n<p>The annual numbers show why 2025 stood out. Reports cited by Newsweek put removals at 25,339 pounds in 2022, 25,949 pounds in 2023, 21,649 pounds in 2024, then 36,863 pounds in 2025, pushing the total beyond 100,000 pounds.<\/p>\n\n\n\n<div class=\"gb-element-a00da4e5\">\n<div><div class=\"gb-looper-46613eed\">\n<div class=\"gb-loop-item gb-loop-item-a8390598 post-32237 post type-post status-publish format-standard has-post-thumbnail hentry category-environment resize-featured-image\">\n<h3 class=\"gb-text gb-text-24a51617\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/more-than-100000-pounds-of-invasive-carp-have-been-pulled-from-the-kansas-river-and-the-scale-of-the-catch-reveals-how-fast-a-river-can-be-taken-over\/32237\/\">More than 100,000 pounds of invasive carp have been pulled from the Kansas River, and the scale of the catch reveals how fast a river can be taken over<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>Crews also widened their footprint, expanding work downstream by about 15 miles, while the Bowersock Dam in Lawrence continues to act as a barrier that helps limit upstream spread. Barriers are not foolproof, especially during high water, but even partial containment can buy time for targeted removal to work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why invasive carp hit ecosystems and people<\/h2>\n\n\n\n<p>Kansas is targeting three invasive carp species, including silver, bighead, and black carp, all introduced to the United States through aquaculture pathways decades ago. <a href=\"https:\/\/www.ksoutdoors.gov\/\" target=\"_blank\" rel=\"noopener\">KDWP<\/a> notes these fish were imported from Asia in the 1970s, escaped into Midwestern waters, and now <a href=\"https:\/\/www.ecoticias.com\/en\/the-invasive-chinese-crab-adapts-to-almost-any-environment-feeds-on-invertebrates-fry-and-even-protected-species-and-competes-with-local-fauna-as-if-the-river-were-its-own\/28663\/\">compete with native fish<\/a> for the same resources.<\/p>\n\n\n\n<p>Their impact is not just ecological, it can be physical. KDWP warns that invasive carp can consume up to 40% of their bodyweight each day, and silver carp may leap when disturbed by boat motors, creating a real safety issue on crowded summer weekends. <\/p>\n\n\n\n<p>Bighead carp can also reach extreme sizes, with individuals reported at over 100 pounds, and KDWP says adults can reach about 4 feet in length.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The tools behind the haul<\/h2>\n\n\n\n<p>Kansas crews are not simply netting at random. Officials describe using electrofishing, gill nets, and specialized equipment such as an \u201celectrified dozer trawl\u201d that stuns fish and collects them as the boat moves forward. The goal is efficiency without turning every removal day into a chaos scene on the water.<\/p>\n\n\n\n<p>It is a game of persistence because the fish can travel. In a KDWP commission briefing, staff noted invasive carp can move more than 10 miles a day, and some studies have documented movements up to 50 miles in 24 hours, which helps explain why new pockets can appear fast after a surge or flood. <\/p>\n\n\n\n<div class=\"gb-element-46696f6d\">\n<div><div class=\"gb-looper-6f438f66\">\n<div class=\"gb-loop-item gb-loop-item-bf1f1f97 post-32207 post type-post status-publish format-standard has-post-thumbnail hentry category-trending-news resize-featured-image\">\n<h3 class=\"gb-text gb-text-64fb0641\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/if-you-see-parakeets-flying-near-your-home-it-is-not-just-a-noisy-visit-the-birds-may-be-telling-you-something-about-the-local-environment\/32207\/\">If you see parakeets flying near your home, it is not just a noisy visit: the birds may be telling you something about the local environment<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>That is also why managers keep talking about barriers, deterrents, and early detection, not just harvest.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What success looks like beyond pounds removed<\/h2>\n\n\n\n<p>Officials say the removals are starting to show benefits. KDWP biologist Liam Odell said, \u201cthese removal efforts appear to have produced positive effects in Kansas waterways and for native species,\u201d pointing to declines in targeted areas alongside the return of native fish.<\/p>\n\n\n\n<p>But pounds are only a proxy. In KDWP briefings, staff have described invasive carp as long-lived filter feeders that are tough to catch with traditional hook-and-line methods, and they have warned that native paddlefish can end up competing with carp for plankton. <\/p>\n\n\n\n<p>So the real checkpoint is a mix of monitoring data, native fish surveys, and whether carp stay pinned below barriers like Bowersock.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1800\" height=\"1013\" src=\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch.jpg\" alt=\"Large net filled with invasive carp being lifted from the Kansas River during wildlife removal operations\" class=\"wp-image-32241\" title=\"\" srcset=\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch.jpg 1800w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch-300x169.jpg 300w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch-768x432.jpg 768w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch-1536x864.jpg 1536w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/05\/invasive-carp-removal-kansas-river-net-catch-150x84.jpg 150w\" sizes=\"auto, (max-width: 1800px) 100vw, 1800px\" \/><figcaption class=\"wp-element-caption\">Wildlife crews haul invasive carp from the Kansas River as part of a large-scale effort to protect native ecosystems.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">The price tag of waiting<\/h2>\n\n\n\n<p>Invasive carp management is expensive, and the bill tends to grow with every year a population becomes established.
