In the perspective of environmental sustainability and the preservation of marine biodiversity, Rosenfeld Ltd, in collaboration with the Department of Life Sciences, of the University of Trieste and the Cape Eleuthera Institute, has been continuing research projects since 2006. The research project concentrates on the marine biology study of the accretion of some of the valuable species of sea sponges.

The research concentrates on the development of techniques for the creation of extensive sponge farming designated marine areas and includes the reproductive characteristics of these organisms in captivity. The operation is done by taking only parts of the specimens, thus preventing the complete removal of the animal. This methodology exploits the excellent natural regeneration ability of the sponge. Many species, in fact, are able to regenerate whole organisms from small fragments.

The species involved in the research are searching the Mediterranean Spongia officinalis, tropical Spongia pertusa and Spongia tubulifera. The experimental farms are located respectively in the Gulf of Trieste and the island of Eleuthera in The Bahamas.

The realization of cultures of these organisms is as important not only from a commercial aspect, it also has beneficial effects on the environment. The presence of a large number of specimens concentrated in restricted areas, would allow a massive larval dispersion thus contributing to a natural repopulation. In addition, the structures used for farming could serve as "artificial reef", by forming new substrates colonized by other organisms as well as areas of shelter and "nursery" for different fish species, thus contributing to raising the biodiversity of the interested farming area.
