This bull frog Eliminated (for now) in the Ebro delta. It must be pronounced with every word of the sentence. maximum attention possible and all necessary nuances, but at least now, however prudent, it can be affirmed loudly and clearly. This large amphibian It was detected as a larva for the first time in 2018. The delta has been hacked as its existence can pose serious problems for the delta ecosystem. preliminary issue and with all available tools.
This summer, five years later and after last summer DNA analysis It was not possible to prove its existence in the Delta during the studies carried out in the waters where this animal was detected. Fishing nets were also used to catch possible specimens, but none appeared.
To verify the validity of the collected data, listening was made at various points, but the frog (Lithobates catesbeianus) song did not come out.
right approach
Why was the (probable) eradication of this species achieved? From Delta Nature Park, they think early detection is the keys, when this American animal is just starting to venture into the wetlands and is also quick and fast. strong performance.
to others invasive species Those entering the Ebro delta, such as the blue vaccine or the apple snail, left much more room for action. For this reason got out of control. In the case of the frog, a six kilometer perimeter at its location is bounded by fences.
Inside closed areathey organized capture and tracking fixed in which organizations, volunteers, research teams and experts participate.
In 2024, verifications will be repeated to confirm accuracy. Destroy at 15 points not detected this year. Generalitat’s technicians assure you that it is still too early to claim victory for sure. However partial attack frog lost this season.

northeast bull frog AmericaIt is one of the most harmful invasive species in the world since it was introduced to Sweden and Finland. fish farming. Its ability to adapt to the environment has allowed it to spread to more than 40 countries, where it has not yet been expelled, despite great efforts. A good example is what is happening in various parts of the country. Germanywhere their populations are not sufficiently reduced.
This frog causes serious imbalances in ecosystems: it is displaced (or directly swallows) to other native amphibians or reptiles, usually changes the structure of vegetation and is a giver diseases and parasites such as the fungus Batrachochytrium dendrobatidis, which is responsible for the decline of many amphibians worldwide.
