## 4 Discussion
Apart from pure bibliometric analysis, these analyses still need to be combined with other relevant sources to have an insight into the development of aquaculture in practice as well as research trends in the development of floating structures. For example, many authors dealt with the implementation of renewable energy sources in the system. [PERSON] et al. [110] proposed the aquaculture ship with self-wind power generation which aims to expand aquaculture to the open ocean, providing an economical and environmentally friendly option. The study of [PERSON] et al. [111] reflects the potential for synergies and obstacles in integrating the operation and maintenance (O&M) activities of offshore wind farms and mariculture. The authors highlight the significance of clear communication, collaboration among stakeholders, and the development of effective regulatory frameworks to reduce the difficulties in integrating operation and maintenance tasks such as logistical complications or others. Wind farm buildings can operate as artificial reefs, fostering biodiversity and supporting marine ecosystems [111]. [PERSON] et al. [112] suggest a conceptual design that includes a variety of renewable energy technologies. Offshore wind turbines, solar panels, wave energy converters, and energy storage systems are examples of technologies which are integrated to provide the necessary electricity for marculture operations such as water circulation, aeration, lighting, and equipment, but confront problems such as high initial investment costs, maintenance requirements, and the variability of renewable energy sources [112]. [PERSON] et al. [4] proposed an alternative, electrified, mariculture system which includes a barge with renewable energy sources. [PERSON] et al. [113] deal with the issues confronting the aquaculture business, such as limited access to the city, poor logistics, and insufficient infrastructure, and propose potential sustainable development options such as promoting small-scale aquaculture, integrating aquaculture with agriculture, and establishing appropriate regulatory frameworks. To ensure the successful establishment of offshore mariculture initiatives, [PERSON] et al. [114] emphasize the importance of sustainable practices, effective governance, and stakeholder participation, underlining the importance of additional study, policy development, and investment to enjoy these benefits while protecting the long-term viability and resilience of coastal ecosystems. [PERSON] et al. [115] suggest spatial planning concepts as a framework for guiding sustainable offshore aquaculture development including the choice of an ideal aquaculture location based on ecological characteristics, taking social and economic factors into account, the importance of including local communities, industry leaders, environmental organizations, and political agencies, guaranteeing compatibility with other marine uses. In [116] the Engel-Blackwell-Miniard model and the global Malmquist-Luenberger index were used to measure and analyze the technical efficiency and productivity of \"marculture area production efficiency\" from both static and dynamic perspectives. Mariculture has a high potential for sustainable food production and economic growth, and the future of seafood production will most likely develop around marculture production with an emphasis on the conservation of natural resources (water, biodiversity, climate, etc.) [117]. The integration of mariculture with other sectors such as renewable energy, coastal tourism, and ecosystem restoration offers intriguing opportunities. Co-location of offshore wind farms with mariculture enterprises, for example, can provide synergistic benefits such as shared infrastructure and decreased environmental impacts. Investments in research and development, innovation, and information sharing are crucial for marculture's future prospects.
