“…Research in this area was developed early in Japan, where fisheries tried to maximize the fish stock exploitation in relationship with the fishes' natural habitats (Ogawa, 1982). In several studies there, the depth, orientation, height, and internal volume of artificial habitat were constructed to mimic certain aspects of the natural habitat as determined by in situ observations (Ogawa, 1982;Nakamura, 1985;Tanoue et al, 2015). Contemporary authors have largely used the principles stemming from this research (Seaman, 1995;Relini et al, 2002;Bortone, 2006;Seaman, 2007;Bortone et al, 2011).…”

Eco-design aims to enhance eco-engineering practices of coastal infrastructure projects in support of ecological functions before these projects are developed and implemented. The principle is to integrate eco-engineering concepts in the early phases of project design. Although ecological losses are inherent in any construction project, the goal of eco-design is to introduce environmental considerations upfront during technical design choices, and not just afterwards when evaluating the need for reduction or compensatory mitigation. It seeks to reduce the negative impacts of marine infrastructure by introducing a new reflexive civil engineering approach. It requires a valuation of nature with the aim of reducing impacts by incorporating intelligent design and habitatcentered construction. The principle advocated in this paper is to design coastal infrastructures, at micro-to macro-biological scales, using a combination of fine and large scale physical and chemical modifications to hard substrates, within the scope of civil engineering requirements. To this end, we provide a brief introduction to the factors involved in concrete-biota interactions and propose several recommendations as a basis to integrate ecology into civil engineering projects, specifically addressed to concrete. 'coastal squeeze', a term introduced by Doody (2004) in recognition of the threat to the existence of coastal habitats caused by the compound impacts of sea-level rise and human activities. The phenomenon is very prominent in developed countries (INSEE, 2013) such as Spain, Italy, Belgium, Japan, China, and the USA, but it is also becoming more prominent in the developing world (e.g., Vietnam, Thailand, Philippines, Myanmar, India and Indonesia) (Phan et al., 2014). It develops rapidly, especially in a context of emergency poverty alleviation and economic development where environmental governance is weak. Around the Mediterranean, urbanization increased from 54% to 66% between 1970 and 2006 (Halpern et al., 2008). Furthermore, the situation is likely to worsen; the world's population is forecast to

Sargassum forests play an important role in coastal waters as habitats for marine organisms, including commercial species. However, human activities have negatively affected their distribution causing a worldwide decline of Sargassum forests. Mapping and monitoring the distribution and biomass of these habitats using acoustic remote sensing techniques is key for their conservation. Nonetheless, most researches based on acoustic remote sensing methods focus on estimations of macrophyte area and its canopy height, and less researches reporting 3D visualization of these habitats. This study demonstrates the use of high-resolution multibeam echosounder (MBES) bathymetric data to visualize the 3D structure of Sargassum forests. Comparing acoustic data and underwater camera photos collected in field surveys, we identified Sargassum individuals as vertical clusters of contiguous sounding points with a base close to the sea bottom in the sounding data of the MBES. Using this criterion, we could distinguish Sargassum echoes, visualize the 3D structure of Sargassum forests and estimate the number of Sargassum individuals in the survey area. Using the relation between thallus length and dry weight of sampled Sargassum plants, standing stock and biomass could be estimated assuming the thallus length was the height of Sargassum plants identified with the MBES.
