Hasanuddin University (UNHAS), through its Faculty of Marine Science and Fisheries, in collaboration with Shanghai Ocean University and Guangdong Ocean University, held the Talent Cultivation & Technical Personnel Training Course, Sino-Indonesia Technical Cooperation on Offshore Marine Eco-Ranching on October 29, 2024. This training aimed to enhance technical and practical capacities in marine eco-ranching management, particularly through artificial reef technology, while also strengthening Indonesia-China relations in marine conservation and blue economy development.
The Dean of UNHAS’s Faculty of Marine Science and Fisheries opened the training by expressing appreciation for the collaboration established in 2022 with the two Chinese universities. He emphasized that China’s vast experience and expertise in maritime affairs provide valuable lessons. “China is an outstanding partner in the maritime field. We hope that through this training, we can learn from the technologies and innovations developed there, which we hope will significantly impact the sustainability of Indonesia’s marine ecosystems,” he stated.
Marine science experts delivered scientific presentations and discussions from Chinese universities. Prof. Zhou Zhang began the training by introducing the fundamental concept of artificial reefs, which are artificial structures designed to replace the functions of damaged natural reefs. According to Prof. Zhang, artificial reefs have both ecological impacts and economic benefits for coastal communities. He explained that these structures support sustainable fishing activities and help reduce pressure on natural coral reefs.
Prof. Zhaoyang Jiang from Shandong University followed with an in-depth explanation of artificial reef design and installation methods. He described various materials used, including concrete, iron, rock, and wood, with each material and design tailored to the local ecological needs. Prof. Jiang highlighted how China’s artificial reef technology has evolved from traditional materials like bamboo to more complex, eco-friendly structures capable of withstanding oceanic pressures.
Dr. Shike Gao from Shanghai Ocean University then delivered insights into the ecological impact assessments of artificial reef installations. According to Dr. Gao, every structure placed in the sea must be evaluated for its ecological, economic, and social effects. Routine surveys of reef areas involve measurements of water quality, sediment, and fishery productivity to determine how artificial reefs can enhance biodiversity and support the livelihoods of coastal communities.
In the following session, Prof. Liqiang Zhao from Guangdong Ocean University highlighted the significant role of shellfish as a marine species that supports the blue economy. Shellfish function as filter feeders that purify ecosystems and hold high economic value in the tourism and food industries. Prof. Zhao noted that Indonesia has great potential to develop sustainable shellfish farming as part of its coastal economic development.
Dr. Jie Zhou, the final presenter, discussed coral reef monitoring and restoration methods. He emphasized the importance of preserving coral reefs, which are increasingly threatened by bleaching due to climate change. Dr. Zhou explained that reef monitoring can be carried out using various modern techniques, such as eDNA, acoustic technology, and even robotics. Additionally, artificial reefs play a role in coral restoration by providing new habitats for marine life. “Coral reefs not only offer food and tourism potential but also act as natural coastal protectors that must be preserved,” Dr. Zhou noted. The training was conducted in a hybrid format and attended by participants from various national and international institutions, including academics, environmentalists, and government representatives. Participant enthusiasm highlighted a keen interest in artificial reef technology as a solution for sustainable marine ecosystem conservation. Through this training, UNHAS aims to take concrete steps in marine resource management and conservation through innovative technology, positioning Indonesia to address future maritime challenges better.
