“…Moreover, the macroalgal colonization of scour protection may be augmented using macroalgae restoration techniques [136,137,144], as macroalgae has been shown to influence the composition and abundance of fish species on rocky habitats [145]. Verdura et al [136] developed a relevant novel technique to restore patches of the canopy-forming alga Cystoseira barbata, while Fredriksen et al [137] developed a method to restore kelp forests using rocks (Figure 7E).…”

As the development of large-scale offshore wind farms (OWFs) amplifies due to technological progress and a growing demand for renewable energy, associated footprints on the seabed are becoming increasingly common within soft-bottom environments. A large part of the footprint is the scour protection, often consisting of rocks that are positioned on the seabed to prevent erosion. As such, scour protection may resemble a marine rocky reef and could have important ecosystem functions. While acknowledging that OWFs disrupt the marine environment, the aim of this systematic review was to examine the effects of scour protection on fish assemblages, relate them to the effects of designated artificial reefs (ARs) and, ultimately, reveal how future scour protection may be tailored to support abundance and diversity of marine species. The results revealed frequent increases in abundances of species associated with hard substrata after the establishment of artificial structures (i.e., both OWFs and ARs) in the marine environment. Literature indicated that scour protection meets the requirements to function as an AR, often providing shelter, nursery, reproduction, and/or feeding opportunities. Using knowledge from AR models, this review suggests methodology for ecological improvements of future scour protections, aiming towards a more successful integration into the marine environment.

“…Other variables to consider in future cumulative impacts for the region include other drivers of fish abundance and distribution, for example, seafloor rugosity (Burgos et al., 2017; Emslie et al., 2014; Rees et al., 2021); exposure and currents (Fulton & Bellwood, 2004; Williams & Bax, 2001); food‐web dynamics (Fu et al., 2020; Lefébure et al., 2013); habitat type and condition (Fulton et al., 2016; Quaas et al., 2019); and larval and recruitment variability (Planes et al., 2009). Sociocultural, economic, and political factors, such as community support, enforcement, and degree of remoteness (Edgar et al., 2014), also influence the performance of marine parks (Glew et al., 2012; Noble et al., 2020, 2021).…”

The coastal environment is not managed in a way that considers the impact of cumulative threats, despite being subject to threats from all realms (marine, land and atmosphere). Relationships between threats and species are often non‐linear, thus current (linear) approaches to estimating the impact of threats may be misleading. We developed a data‐driven approach to assessing cumulative impacts on ecosystems and apply it to explore non‐linear relationships between threats and a temperate reef fish community. We use data on water quality, commercial fishing, climate change, and indicators of recreational fishing and urbanisation to build a cumulative threat map of the Northern Region in New South Wales, Australia. Using statistical models of fish abundance, we quantified associations among threats and biophysical covariates and predicted where cumulative impacts are likely to have the greatest impact on fish. We also assessed the performance of no‐take zones, to protect fish from cumulative threats across two marine protected area networks (marine parks). We found that fishing has a greater impact on fish than water quality threats (i.e., percent increase above the mean for invertivores was 337% when fishing was removed c.f. 11% when water quality was removed inside no‐take zones), and that fishing outside of no‐take zones affects fish abundances inside no‐take zones. Quantifying the spatial influence of multiple threats enables managers to understand the multitude of management actions required to address threats.This article is protected by copyright.

“…A GoPro Hero 7 camera (www.gopro.com) was secured to each setup with a GoPro mount, with 15-m synthetic lines for deploying and retrieving the camera system and a floating buoy to allow clear identification at the surface. This simple design (commonly called mini-BRUVS/RUVS) are more compact for deployment from smaller vessels or while diving (Harasti et al 2014a;Kiggins et al 2018;Quaas et al 2019), and by association also have less drag, which would otherwise be an issue given the high currents (.2 m s À1 ) that occur in these channels that can make retrieval difficult with larger style BRUVS.…”

Temperate soft corals are found in many estuaries around the world and often form large habitats in these environments, yet the functional ecology of soft corals is poorly understood. To understand the functional role of a soft coral in temperate ecosystems, we examined the role of the endangered Dendronepthya australis cauliflower coral as habitat for fishes and invertebrates, and whether associated species used the soft coral as a food source. Using Bayesian stable isotope mixing models of δ13C and δ15N values of soft corals and a suite of potential invertebrate consumers, we found that five of eight soft-coral-associated invertebrates were all likely to be feeding almost exclusively on the soft corals. In situ feeding experiments conducted using baited remote underwater video systems (BRUVS) with soft coral cuttings as ‘bait’ did not identify any larger species as consumers. Fish assemblages studied using remote underwater video systems (RUVS) were diverse in the soft coral habitat and overlapped with assemblages of both sediment and seagrass environments. These results highlighted that these soft corals have a valuable trophic role in estuarine food webs through trophic transfer of nutrients via invertebrate consumers, and that soft coral habitats are used by commercially and recreationally important fishes.
