In the lagoon of the Mar Menor, an area with more than 50 live specimens has been found. The government has fenced this area with nets so that it is not crossed by motor boats.
En la laguna de el Mar Menor se ha encontrado una zona con más de 50 ejemplares vivos. El gobierno ha cercado esta zona con redes para que no la crucen las embarcaciones a motor.
The mass mortality of the bivalve Pinna nobilis in the Mar Menor salt lagoon has been more than 90%. It has taken place at the same time as the mass mortality in the Western Mediterranean sea due to the epidemy of Haplosporidium pinnae which has killed most of the population of this endemic mollusk. Haplosporidian parasite has been found in digestive glands of infected individuals in the Mediterranean sea but not in the glands of the ones in the Mar Menor. That's why it doesn't seem to have been the cause of the mortality of pen shells or fan mussels in the coastal lagoon as there is no evidence this parasite. Fortunately a few groups of individuals have survived in the lagoon due to the highest level of salinity of this place.
Thank you very much for completing my spotting with your valuable information. In addition to the dangers you mention, there is another very important one: human greed. In the waters of the lagoon, when it rains torrentially, as is happening in recent years due to climate change, waters are poured with metals from nearby mines, and also fertilizers, pesticides, hervicides, etc. from the irrigation of large extensions of intensive agriculture that is being developed in the vicinity. My sister, Isabela, is doing a great job collaborating with the group PACTO POR EL MAR MENOR and denouncing this situation.
