BTN News: As jellyfish populations continue to surge in certain areas along the Spanish coast, local authorities and regional governments are seeking effective measures to minimize the risk to beachgoers who flock to these shores during the summer months. One of the most commonly adopted strategies involves the deployment of anti-jellyfish nets, which act as physical barriers to keep these marine creatures at bay. These nets have become a familiar sight, particularly in regions like Murcia, where officials have already confirmed their reinstallation this year along several beaches in the northern part of La Manga del Mar Menor and in the municipality of San Pedro del Pinatar.
While these nets are intended to make swimming safer, they have sparked concern among scientists. Experts argue that these barriers can disrupt the natural flow of water in the areas where they are placed. Ángel Pérez Ruzafa, a respected scientist, highlighted the potential negative impact last summer, noting that the nets not only cause mortality in various species that become trapped but also encourage the rapid growth of algae. This, in turn, can impede water currents in the Mar Menor, leading to the accumulation of organic matter. As this matter decomposes, it can result in the fouling of beaches, the release of unpleasant odors, and localized depletion of dissolved oxygen levels—factors that could have broader ecological consequences.
Despite these warnings, the regional Ministry of Environment has reassured the public that the installation of these nets will be carried out with precision, only in areas where the situation demands such measures. The authorities plan to have these nets in place by the end of July. The Scientific Advisory Committee of the Mar Menor has also weighed in, stating that the current condition of the sea is favorable for the installation of these nets. However, they have ruled out the extensive deployment seen in previous years, where up to 40 kilometers of nets were used. Additionally, they emphasize the important role jellyfish play in the marine food chain, as they help regulate the ecosystem by preventing the excessive buildup of nutrients.
The debate surrounding the use of anti-jellyfish nets underscores the complex challenge of balancing human safety with environmental preservation. As coastal communities continue to grapple with the growing presence of jellyfish, finding a sustainable approach that protects both people and marine ecosystems remains a priority. Whether the surgical placement of these nets will prove to be a viable long-term solution or merely a temporary fix is yet to be seen, but it is clear that the issue demands ongoing attention and careful consideration from all stakeholders involved.
