The nacres are reborn in the Mar Menor: 450 new specimens, controlled salinity, and a feeling of "caution"

The ecological situation of the Mar Menor is showing signs of improvement, with the recent detection of 450 new specimens of the common nacra, a decade after a mass mortality event. This increase brings the total to over 600 nacras, with about 66% being juvenile. Research indicates that a decline in bacterioplankton levels since 2024 has allowed the nacra to begin a new reproductive cycle. The nacra, endemic to the Mediterranean, can create its own ecosystem, hosting various species. Continuous monitoring is essential to track population changes and identify critical habitats. Stable salinity levels are crucial for nacra development, and current conditions are favorable. Additionally, the seahorse population has also increased, demonstrating resilience despite past environmental challenges. However, experts remain cautious about future developments.
