What is an artificial reef?
An artificial reef is a structure intentionally placed on the seabed to mimic the functions of natural reefs and that is therefore able to protect and regenerate populations of marine organisms.
Habitat enhancement usually results in increased food availability and shelter from predators, as well as new recruitment areas for juveniles of various species (benthic invertebrates or fish), which explains the increase in biomass of organisms associated with these structures after their installation.
By providing habitat and protection for a large number of species, there is an increase in fish abundance and therefore an improvement in fisheries. Indeed, the reproduction of these fish as well as their protection by the reef will allow a spillover effect towards the surrounding fishing areas. Thus, fishermen will be able to practice their activity without hindering the good reproduction of each species, allowing them to access a more sustainable fishery.
Scientific monitoring
We will carry out a scientific monitoring to study the colonisation of marine species on the reefs over time. It will be implemented over a period of 5 years minimum and will be based on inventories of the populations using underwater robots called ROV (Remote Operated Vehicle). A report will be produced each year, in order to study the evolution over time. A final assessment will be made in the last year with possible new phases.
This monitoring will not only prove its effectiveness but also raise awareness of the loss of biodiversity, fisheries resources and the importance of ecosystem restoration.
