Artificial reefs (AR), which are integral tools for fish management, ecological reconciliation and restoration efforts, require non-polluting materials and intricate designs that mimic natural habitats. Despite their three-dimensional complexity, current designs nowadays rely on empirical methods that lack standardised pre-immersion assessment. To...

L'oeil humain perçoit dans la lumière visible en 3 bandes R V B, alors que les satellites munis de caméra hyperspectrale divisent la lumière en plusieurs centaines de bandes de l'ultraviolet au proche infra-rouge. Ils permettent ainsi d'établir des cartographies terrestres ou chaque pixel est composé de ses coordonnées et des longueurs d'ondes qui...

Artificial reefs (ARs) are designed to mimic natural habitats and promote marine life. Their effectiveness is however debatable and can depend on factors such as structural complexity and construction material. Old artificial reefs (OARs) were made of concrete mold of simple geometric shapes, limiting their ability to mimic the complexity of natura...

Artificial reefs (AR) must be built according to their objective and show high complexity to mimic the characteristic of natural habitats. To enhance the integration of artificial structures into ecosystems, a new quantitative method has been developed to evaluate their complexity, using 3D computer-aided design (CAD) models of ARs. The method util...

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...
