Unsustainable use of resources, habitat destruction, pollution, invasive species, and climate change have resulted in an unprecedented decline in biodiversity and essential ecosystem goods and services. In this context, nature can inspire engineering to address environmental issues for the sustainable use of the sea. This means by creating an objec...

Artificial reefs are submerged structures deliberately placed on the seabed to mimic some characteristics of a natural habitat, they have been used for thousands of years by fishermen to improve their fishing practices and recently they are also used for the protection or even the restoration of certain marine habitats. Despite these various object...

Habitat destruction is one of the main causes of the decline of biodiversity and of fishery resources in the marine environment. An artificial reef (AR) could be a tool for protecting or restoring these habitats and their declining biodiversity, and also help to enhance sustainable fisheries. The goal is to design non-polluting structures that best...

Presentation of the 3D printed artificial reefs project in the Monaco marine reserve of Larvotto. Experiments carried out on the biofilm development and 3D complexity assessment are described.

The formation of biofilm to surface has been used as a bio indicator to determine the quality of various materials used for the production of artificial reefs (concrete, reconstituted naturel rock and dolomite) to established the first link with the trophic network around the artificial reefs. The microorganisms community that form the biofilm has...
