Artificial Reefs: Perceptions and Impact on the Marine Environment

Conference paper


Artificial reefs have a positive image in the media and the public. However, if they soon appeared as a convenient response to fisheries depletion, there has since been a shift between this ideal perception and a real understanding of their functioning and impact.

The assessment of their actual performance is constrained by a knowledge deficit about ecosystems’ natural variability, the definition of appropriate spatial and temporal scale studies, and the difficulty and cost of field surveys. In such a context, a number of questions can be raised, such as: (1) Is there an increase or redistribution of biological resources? (2) Are habitats a limiting factor for resources under heavy exploitation or limited recruitment? (3) Is ecosystem engineering enough and adapted as a response to resources degradation?, (4) What kind of control may be applied in regard to the system’s possible modification?

In France, artificial reefs are mainly used for the purpose and benefit of coastal fisheries. In this context, multiple experiences may become risky in a free access system and not lead to a significant reduction in marine pollution and degradation sources. In addition, in such conditions, technological improvements could become useless.

Yet the demand is increasing and becoming more diversified. New perspectives are opening with the awareness of better control of uses at sea and the convergence of research-related issues concerning biodiversity, ecological engineering, marine protected areas, and marine areas specifically devoted to renewable energy devices. Besides, the technological improvement of monitoring tools supported by better experimental and follow-up procedures should help to achieve more significant and effective results for the benefit of coastal zone management.
