Huge catfish are being sighted more and more frequently in Baden-Württemberg. Experts are puzzled as to why the animals reach such enormous proportions.
Climate change can be felt worldwide and does not stop at our front door. The ever more extreme temperatures bring about serious changes for flora and fauna. This also affects aquatic life, where there are many losers but also some winners.
In Baden-Württemberg, an increase in catfish has been observed for years. The European catfish appears to be benefiting and is continuing to spread as a result. This can also be seen from the size. Specimens of more than two meters are not uncommon.
In Spain, Italy and France, the catfish is now considered invasive. As is so often the case, man has promoted this himself, since most catfish come from the south-eastern European pond economy. Species are referred to as invasive if they not only spread, but also damage other species, habitats or entire ecosystems.
The question of the reason for the extreme size of the catfish in Baden-Württemberg remains unanswered. The Agricultural Center (LAZBW) sees a threat to salmon and allice shad, although little is known about the behavior and growth of catfish under natural conditions.
You can see that these huge catfish are also caught on Instagram under #welsangelnindeutschland.
