Marine geophysical and geological investigations are crucial for evaluating the construction suitability of artificial fish reefs (AFRs). Key factors such as seabed topography, geomorphology, sub-bottom structure, sediment type significantly influence AFR design site selection. Challenges material sinking, instability, scouring effects should be critically considered addressed in AFR, particularly areas with soft mud or dynamic environments. In this study, detailed were conducted approximately seven months after deployment reef materials experimental zones around Xiaoguan Island, located western South Yellow Sea, China. Based on morphological factors, using data from multibeam echosounders side-scan sonar, study area was divided into three geomorphic zones, namely, tidal flat (TF), underwater erosion-accumulation slope (UEABS), inclined shelf plain (IEASP) zones. The focus UEABS IEASP where (concrete stone blocks) deployed earlier. comprehensive interpretation results multi-source high-resolution acoustic images showed that average settlement individual zone 0.49 m, their surrounding experienced little to no scouring. This suggested formation an effective range height, making suitable construction. However, zone, consisted mud, causing sink deployment, preventing rendering unsuitable These findings provided valuable scientific guidance other similar coastal regions.

In recent years, additive manufacturing technologies have been employed for ecological projects, especially those connected with artificial reefs. This approach brings a lot of advantages, including the design more complex structures, surfaces fitted to needs water organisms. technology can effectively support and engineering, in restoration efforts. The main aim this article is demonstrate state art further perspectives development coral based on critical analysis literature, supported by selected case studies. describes current used creation reefs, putting emphasis manufacturing, evaluates currently materials, summarizes influence ecosystems through It also discusses challenges limitations 3D printing reefs as well presents trends directions. most important findings show that analyzed field promising interdisciplinary research area practical implementations require collaboration between specialists from different branches.
