“…In some jurisdictions, these deployments have been justified as a response to declining catch (Pauly andChua 1988, Milon 1989) or a response to declarations of marine protected areas that have excluded recreational fishers from popular natural reef fishing spots (Fabi et al 2015). In many countries, artificial reefs have become important elements of frameworks for integrated fisheries or coastal management (Baine 2001, Fabi et al 2011, Moura et al 2006, Ramos et al 2007, Kim et al 2008, Leitão et al 2007, Tessier et al 2015, Vivier et al 2021 however Baine (2001) asserted that 50% of programs had not achieved their objectives, mainly due to poor design and planning (see also Pickering and Whitmarsh 1997, Jan et al 2003, Campbell et al 2011, Hackradt et al 2011, Lima et al 2019.…”

Artificial reefs have many applications but are best known for their deployments to enhance recreational fisheries by creating new habitat in areas where natural reef is otherwise limited. The expectation is that fish assemblages will take up residence on artificial reefs and that these assemblages will become at least similar, if not more diverse and abundant, to those on natural reefs. Although designed, purpose-built artificial reefs are becoming more widely used in support of recreational fisheries and many of the historic issues have been resolved, conservation practitioners and managers still face challenges as to the type, number, and arrangement of structures and where to deploy them to maximize benefits and minimize risks. The ecological literature was reviewed to develop and enhance contemporary principles of artificial reef best practices for utilization. Our review identified optimal shapes, vertical relief, void spaces, and unit arrangements for increasing volumes and diversity of catch to recreational fishers and we provide a tool for identifying the least constrained areas for artificial reef deployment. We suggest; (a) monitoring of noncatch motivators in combination with quantitative indicators of the fishing activity (e.g., catch rate and effort) will provide the best understanding of success or failure of an artificial reef deployment; (b) choosing target species for informing purpose-built artificial reef designs to be reef-associated, demersal, philopatric, territorial, and obligatory reef species that are desired by local recreational fishers; and (c) considering the ecosystem services provided by artificial reefs beyond those associated with recreational fishing.

“…Artificial structures or Artificial Reefs (AR) have been used for decades to attract fish or to protect shallow coastal zones from trawling (Jensen et al 2000), and their development has intensified over the three last decades (Vivier et al 2021). Such structures are also favourable areas for biodiversity as they act as settlement zones and nurseries for many marine species (Patranella et al 2017) by providing a novel habitat and supporting the primary production of organic carbon and its transfer through the trophic network (Charbonnel et al 2002;Langhamer and Wilhelmsson 2009;Layman et al 2016;Komyakova and Swearer 2018;.…”

Influence of infrastructure material composition and microtopography on marine biofilm growth and photobiology

The impact of concrete composition and roughness on the formation of microalgal biofilms and their photobiology were studied on marine infrastructures presenting four different compositions combined with two degrees of roughness (rough and smooth). The structures were first inoculated with a natural microphytobenthic biofilm and immersed in sterilised seawater with a controlled photoperiod for six days. Photosynthetic activity was assessed with an imaging PAM-(Pulse Amplitude Modulated) fluorometer and microtopography was monitored in parallel with a 3-D camera. The results indicated that roughness had an impact on the biofilm biomass, its physiological status and its photosynthetic efficiency and capacity. The assessment of surface roughness indicated that negative reliefs were preferably colonised by MPB (microphytobenthos) cells with better photosynthetic performances. Moreover, MPB biofilms showed better photoacclimation in these microhabitats than on the positive and smooth reliefs. This study confirms the importance of microhabitat for biofilm formation and their photobiology.

“…Today, there are many submerged ARs of various shapes and materials [1][2][3][9][10][11]. These structures are submerged for diverse reasons such as improving fish production, as well as for the protection, conservation and restoration of habitats, or in relation to economic activities including fisheries, stock management, aquaculture, renewable energy, research and development of new materials and structures [10,[12][13][14].…”

An experimental artificial structure was deployed in March 2014 on the intertidal zone of the Bay of Seine (eastern part of the English Channel), at intervals of one year until April 2018, i.e., from February 2015 onwards, two blocks were collected in April each year. This study provides an inventory of sessile and motile invertebrates living on the artificial hard-bottom and describes the stages of colonization and succession during the four-year study. A total of 84 taxa were identified including 13 sessile and 71 motile taxa. For the sessile fauna, only two taxa Balanus crenatus and Mytilus edulis had colonised the blocks in 2014, and the Taxonomic Richness (TR) was relatively stable during the next three years (between 8 and 10 taxa). The TR of the motile fauna showed an increase between 2014 (5 taxa) and 2015 (34 taxa), and then decreased from 54 taxa in 2017 to 29 taxa in 2018. The abundance of the sessile fauna was very high in 2014 due to the rapid settlement of the barnacle Balanus crenatus, which remained the dominant species throughout the study. Another barnacle Perforatus perforatus, the blue mussel Mytilus edulis and three ascidians including two non-indigenous species Perophora japonica and Corella eumyota, and Molgula sp. were also among the dominant taxa of the sessile fauna. In April 2014, the dominant motile taxa was the decapod Carcinus maenas juvenile, then in 2015 the fauna became dominated by pioneer taxa such as the amphipod of the genus Monocorophium and the tanaid Zeuxo holdichi. A reduction of mean abundance was observed in the last three years of the study, combined with diversification of the dominant species especially those of small size such as Peracarida. The study shows that the colonization of such blocks deployed on oyster tables in the intertidal zone is efficient to test the ability of building material to be colonized in this transition zone.
