There Venice lagoon is facing a growing biological threat, which could be serious implications for its delicate ecosystem. The arrival of sea nutan alien species probably originating from waters Americans, is raising concerns among environmentalists and researchers.
What is Sea Walnut?
The sea walnut, scientifically known as Mnemiopsis leidyiis a gelatinous organism that is part of the family from the ctenophores. Despite its harmless appearance, this species has proven to be a voracious predator of small fish, zooplankton and eggs fish. Its arrival in the lagoon occurred accidentally, probably through the waters of ballast of the ships that they trade globally.
Ecological and Economic Impact
The arrival of this species in a new habitat can lead to serious ecological imbalances. Being an apex predator in its new environment, the sea walnut has no natural predators in the Venice Lagoon, which allows it to multiply rapidly and exhaust the resources food from others marine species indigenous. This not only does it damage local biodiversity, but could be also have repercussions on the economy of the region, especially for communities that depend on fishing and tourism linked to the health of the lagoon ecosystem.
Local authorities and research groups are monitoring carefully the situation, trying to better understand how manage the expansion of the sea nut e minimize its impact. Strategies under consideration include check of the population through natural methods and the strengthening of regulations on treatment of the waters of ballast from the ships.
This invader gelatinous it may seem minor, but its implications are enormous. The challenge is great, but with research continues and collaboration internationalhopes of containment remain alive.
