“…This phenomenon is consistent with Zhou et al (2018), who explored how hypoxia affects the behavior of the sea cucumber, Apostichopus japonicus. At the other extreme, the habitat usage by the crab C. japonica was not influenced by low DO, which may be related to its strong hypoxia tolerance, flexible usage of various habitat types like rock and sand (Yatsuya and Matsumoto, 2021), and its territorial nature (Fowler and McLay, 2013;Yu et al, 2020). Zhu et al (2022) examined how complex habitats can reduce the territorial behavior of crabs.…”

“…What has not been explored in detail is how hypoxia affects the behavior and exposure of individuals in complex habitats and how this differs among reefdependent species that exhibit highly specific habitat affinities. Habitat assessment based on a field survey of reef-dependent species demonstrated species-specific preferences under normoxic conditions (Yu et al, 2020). Whether hypoxia would cause relatively simple shifts of individuals among reefs that are predictable from species information on preferences and swimming behavior is not known (e.g., generalist good swimming species move to nearby reefs).…”

Reef habitat in coastal ecosystems is increasingly being augmented with artificial reefs (ARs) and is simultaneously experiencing increasing hypoxia due to eutrophication and climate change. Relatively little is known about the effects of hypoxia on organisms that use complex habitat arrangements and how the presence of highly preferred AR habitat can affect the exposure of organisms to low dissolved oxygen (DO). We performed two laboratory experiments that used video recording of behavioral movement to explore 1) habitat usage and staying duration of individuals continuously exposed to 3, 5, and 7 mg/L dissolved oxygen (DO) in a complex of multiple preferred and avoided habitat types, and 2) the impact of ARs on exposure to different DO concentrations under a series of two-way replicated choice experiments with or without AR placement on the low-oxygen side. Six common reef-dependent species found in the northeastern sea areas of China were used (i.e., rockfish Sebastes schlegelii and Hexagrammos otakii, filefish Thamnaconus modestus, flatfish Pseudopleuronectes yokohamae, sea cucumber Stichopus japonicus, and crab Charybdis japonica). Results showed that lower DO levels decreased the usage of preferred habitats of the sea cucumber and the habitat-generalist filefish but increased the habitat affinity to preferred habitat types for the two habitat-specific rockfishes. Low DO had no effect on the crab’s habitat usage. In the choice experiment, all three fish species avoided 1 mg/L, and the rockfish S. schlegelii continued to avoid the lower DO when given choices involving pairs of 3, 5, and 7 mg/L, while H. otakii and the flatfish showed less avoidance. The availability of ARs affected exposure to low DO for the habitat-preferring rockfishes but was not significant for the flatfish. This study provides information for assessing the ecological effects and potential for adaptation through behavioral movement for key reef-dependent species under the increasing overlap of ARs and hypoxia anticipated in the future.

“…Trapping and visual census are common sampling methods used with ARs and can cause differences in the estimated species composition (Plumlee et al 2020). Dominant species based on the two sampling methods in our analysis had high similarity that reflected common species in the northeastern China Sea—for example, C. japonica (Zhang et al 2016) and the Korean Rockfish (Yu et al 2020). However, the Chameleon Goby was classified into SA3 and occurred as a dominant species in the visual census but was rare in trap samples.…”

“…Species archetype 6 was comprised of fish species that are known to be associated with rocky habitats (Zhang et al 2015; Yu et al 2020), except for the Black Scraper Thamnaconus modestus , which tends to be located close to ARs but does not inhabit them (Takahashi et al 2010). In our analysis, SA6 showed a positive relationship with the increasing complexity of substrate and with increasing proximity to ARs (Table 4); these habitat preferences were consistent with those reported in other studies (Takahashi et al 2010; Zhang et al 2015; Yu et al 2020).…”

“…The four dominant species of SA4 have been broadly explored by researchers regarding their preference for complex habitat, especially ARs (Takeo 1999; Vazquez Archdale et al 2003; Kim and Kang 2016; Zhang et al 2018b). Korean Rockfish, Fat Greenling, and C. japonica had a preferred distribution at around 20–22°C (Yu et al 2020), and Hannah et al (2008) reported that the highest successful rate of Sebastes spp. capture occurred at depths less than 30 m, which was consistent with the responses of species in SA4 to environmental variables.…”

The placement of artificial reefs (ARs) influences, to various degrees, a wide range of epibenthic species, whereas most assessments focus on target or focal species. Methods of capturing the responses of many species can inform management about the full range of likely responses of species to the location and arrangement of ARs. Performing many single‐species analyses presents difficulties in interpretation. We used monitoring data from 14 surveys from June 2017 to August 2020 in an area with ARs deployed in the Bohai Sea, China. Both trap and visual census data were collected, and a suite of environmental variables was also collected or estimated for sampled sites and for spatial cells throughout the study area. The data were used to fit a species archetype model (SAM) that relies on the shared responses of species to environmental variables. The many species were grouped into six distinct archetypes. Species membership in the archetypes was confirmed by comparing results to the isometric feature mapping and partitioning around medoids (ISOPAM) approach, which relied on species co‐occurrence applied to the same data. The SAM results were also validated by comparing archetypes determined with fitting to predictions from a single survey that was not used in fitting. The six archetypes identified by the SAM had member species that differed in dependence on substrate types, distance to the nearest AR, distance to the nearest gravel, temperature, dissolved oxygen, time since AR deployment, and sampling method. The importance of the environmental variables was assessed by computing the changes in predicted occurrence probabilities of the archetypes when environmental variables were varied with the other environmental variables set at their minimum, mean, maximum, or optimal values. Species archetype modeling provides a valuable approach for predicting occurrence probabilities of epibenthic species assemblages in response to the locations and arrangement of ARs, and results can inform management related to fishing enhancement and conservation.
