In a significant development, technicians from the Segura Hydrographic Confederation (CHS) recently announced Zebra Mussels Discovered in La Pedrera Reservoir located in the Vega Baja region of Alicante. This finding emerged during the CHS’s targeted campaign to monitor zebra mussel larvae and adults in various reservoirs associated with the Tajo-Segura transfer infrastructure.
The ongoing campaign involves technicians actively collecting samples from reservoirs such as Talave, Camarillas, Azud de Ojós, Crevillente, and La Pedrera.Technicians made this discovery during routine monitoring in La Pedrera, further expanding the list of affected reservoirs in the region.

The invasion of zebra mussels poses a significant threat to continental waters. In just a few years, these invasive species rapidly expanded in the Camarillas and Talave reservoirs, prompting urgent measures from the CHS.
In response to this critical discovery, the CHS urges water users and individuals active in basin reservoirs to diligently clean any equipment that has come into contact with the waters. Accompanying this revelation is the CHS’s specific dissemination campaign under the slogan “Alert!, zebra mussel. Don’t let it get to you.” The goal is to raise awareness about the potential inadvertent spread of water pollution.
The zebra mussel, identified as one of the most impactful exotic invasive species in continental waters, has prompted controlled decreases in water levels in affected reservoirs. The CHS, aligning with its 2022-23 Zebra Mussel Shock Plan, aims to eliminate adult specimens and weaken larval populations through strategic measures.

This discovery emphasizes the collective responsibility to mitigate the ecological and economic impacts of invasive species. As the CHS continues its efforts, it calls on the community to actively participate in safeguarding water bodies and preventing the further proliferation of zebra mussels.
