Shellfish reefs were once common features in temperate coastal waters and estuaries. However, anthropogenic impacts have resulted significant declines these ecosystems globally. Whilst a growing body of scientific literature restoration projects demonstrated the success using oysters, at both local ecosystem-wide scales, initiatives mussels are relatively new. Due to lack long-term data on ecological impact restored mussel reefs, information assist practitioners identifying potential positive negative outcomes is limited. introductions occurred every continent, detailed documentation exists their ecosystems. Such thus invaluable as studies can contribute knowledge predicting ecosystem changes following introductions. Through compiling derived from 318 published articles, unplanned found impacts, context- species-specific. In eutrophic water bodies, typically considered positive, particularly shallow-water benthic communities. It was also found, however, that reduce zooplankton biomass, native occasionally implicated increasing cyanobacteria concentrations. Despite instances, this review presented multiple lines evidence introductions, when undertaken intentionally suitable locations, would considerable scale.

Context Reef installation is increasingly considered for urbanised estuaries to enhance and restore ecological functions. Restoration structures are expected provide nekton habitat benefits, but early outcomes poorly understood. Aims This study assessed assemblage variation associated with an oyster reef restoration site, situated within the anthropogenically modified Port River–Barker Inlet estuary. Methods Nekton communities environmental variables were measured 6 weeks before, 14 months following restoration, at a control site. Modelling was used assess spatio-temporal variation. Key results Video monitoring detected 34 species, harvestable comprising 60.3% of total abundances. assemblages strongly influenced by interannual effects, few being directly related activities. supported non-native gobies during study. Conclusions These suggest that small-scale can have little detectable impact on fish in stages estuarine restoration. distinct seasonal Implications In urban characterised pre-existing artificial structures, small trial reefs may be functionally redundant as habitats until sufficient spatial-scale functional changes achieved.
