Abstract

To date, the only practicable way to obtain biomass of large sponges is in situ breeding, based on the technique of asexual reproduction by fragmentation. Indeed, some of the most valuable sponges of cosmetic and/or pharmacological interest have shown promising results when grown on systems suspended in the seawater column, suggesting significant expansion potential for sponge mariculture. Recent studies have shown how some sponge species grow near floating mariculture facilities. Sponge rearing near these plants is an extremely innovative technique that contributes to the development of new integrated multitrophic aquaculture (IMTA) systems aimed at creating sustainable, resilient and competitive aquaculture. These promising results have highlighted the need to develop new marine sponge rearing methods in different ecological conditions in order to support the diffusion of this organisms in mariculture activities also for bioremediation purposes.
