The Aquaculture Technological Center of Andalucía (CTAQUA) has implemented red seaweed cultivation in marsh areas of Bahía de Cádiz, Spain as a new income source. This proposal is part of the European Acces2Sea project.

With this measure, they expect to provide a "new source of income for the operators of the estuaries". Along with their more traditional activities such as salt extraction and extensive fish farming. Furthermore, "it will contribute to the conservation of these spaces of great natural and cultural value".

The methodology used in the cultivation is based on its vegetative growth from seedlings attached to ropes. These ropes are tied too to a neutral or semi-buoyant pond, protected by Tsiane Acuicultura Multitrófica S.L.U. This Cádiz-based company protects the ecosystemic natural aquaculture of that part of the country.

"Thanks to Access2Sea we collaborate with Tsiane too. We work with them to provide alternatives in the diversification of crop species. Also, with the introduction of these marine macroalgae for commercialization", María Galindo, CTAQUA person in charge, commented.

Finally, this work "is accompanied by an evaluation of the company's business model. The Bahía de Cádiz European Center for Business and Innovation (CEEI) is responsible for carrying this", she added.
