The Mar Menor
There have been reports suggesting that the Mar Menor jellyfish population has been significantly reduced by an ongoing campaign aided by local fishermen. Some 42 km of protective nets have been installed in this large salt lagoon on the Costa Calida, Spain, to help protect the popular beach areas and this has been mostly successful in preventing jellyfish infestation during the busy summer seasons of the last 2 years (2008 and 2009). Seventy eight tonnes of jellyfish were netted last year by local fishermen on the Mar Menor, a significant reduction compared to the 5,000 tonnes removed between 2000 and 2002. The oceanographic institute in Lo Pagan has been monitoring the jellyfish situation. The Mar Menor, formed by a narrow spit of land known as La Manga (The Sleeve) has some of the most popular seaside resorts along the Costa Calida, boasting wonderful sandy beaches and safe warm bathing waters, which are particularly renowned for their healing properties, being very high in salt content. The Mar Menor and Costa Calida are situated within the province of Murcia, in south-eastern Spain, some of its best known resorts include Los Alcazares, San Pedro del Pinatar, Santiago de la Ribera, Los Narejas, Los Urrutias, and San Javier.
