Algal bloom from Asia poses a threat to take over the entire Cádiz coastline.

The Junta de Andalucía has taken a proactive approach to addressing the invasive Asian clam, Rugulopterix okamurae, along the coast of Cádiz. Since its first detection in the Strait of Gibraltar in 2015, the Asian clam has spread across the entire Andalusian coastline, including Cádiz [1].

To combat this environmental threat, the Junta de Andalucía has been working closely with municipalities, the fishing sector, companies, and the scientific community to offer real solutions within its competencies [2]. As a result, definitive protocols for the removal, handling, and use of the Asian clam have been established [3].

One such solution involves large-scale mechanical removal of the seaweed from beaches, particularly La Caleta, where authorities have extracted approximately 1,200 tonnes since May 2025 [1][2]. Despite ongoing efforts, the vast quantities washing ashore with westerly winds pose a significant challenge [1].

In an effort to transform this problem into an opportunity, a local company has proposed recycling the collected seaweed into biomass products such as beverage containers, fuel, and fertilizer [2]. This innovative approach could repurpose the invasive alga as a raw material for sustainable products, potentially reducing waste and supporting green industries. However, this strategy requires approval from the environment ministry and negotiations with regional authorities [2].

The Management Plan, now open for everyone interested to study and make contributions to improve, aims to transform the environmental threat posed by the Asian clam into an opportunity for the future [6]. It includes a roadmap for commercialization and valorization of the Asian clam, as demanded by municipalities and various sectors [7].

Moreover, the plan establishes legal mechanisms for municipalities and interested companies to use the Asian clam biomass legally, safely, and without the Ministry's refusal [8]. However, experts caution that while recycling is a useful strategy, it cannot alone eradicate or significantly diminish the invasion due to the vast quantities arriving continuously [2].

The plan approved by the Junta de Andalucía's last Council of Government also establishes measures for monitoring, control, and the use of biomass to mitigate the impact of the Asian clam on the Andalusian coasts [9]. The delegate from the province of Cádiz has emphasized the serious and rigorous work done to convert the Asian clam, a waste, into a resource with both environmental and economic value [4].

The Asian clam has been detected in various locations along the Cádiz coast, including Puerto Sherry, El Puerto de Santa María (the westernmost location in Andalusia where it has been detected) [1], and Conil, where it is not ruled out that it is established in the hard bottoms of this location [5].

The Junta de Andalucía has expressed its support to the numerous coastal municipalities of Cádiz and all of Andalusia, which have been affected by the Asian clam for years [10]. The delegate has reiterated that the Junta de Andalucía will continue to accompany and promote various projects, facilitating public-private collaboration to turn the Asian clam problem into a solution [6].
