In recent years, with the increasing demand for high-quality aquatic products and the decline of fishery resources in coastal waters, deep-sea aquaculture has emerged as a crucial solution. The development of deep-sea aquaculture cage technology has played a significant role in this process.
Early deep-sea cages were relatively simple in structure and had limited resistance to harsh sea conditions. However, continuous technological innovation has led to remarkable improvements. The materials used for cages have evolved, with the application of high-strength and corrosion-resistant alloys and synthetic fibers, enhancing the durability and stability of the cages. The design of cage structures has also become more sophisticated, adopting streamlined shapes and flexible connection mechanisms to better withstand strong currents, waves, and typhoons.
Automation and intelligent technologies have been gradually integrated into deep-sea aquaculture cages. Sensors are installed to monitor water quality parameters such as temperature, salinity, dissolved oxygen, and the growth status of cultured organisms in real-time. This data is transmitted back to the shore control center, enabling farmers to remotely adjust feeding strategies, monitor equipment operation, and detect potential problems promptly, thus improving the efficiency and success rate of aquaculture.
In addition, the scale of deep-sea aquaculture cages has been expanding. Larger cage volumes provide more spacious living environments for cultured fish, reducing stress and disease occurrence rates. Some advanced cage systems are also equipped with integrated functions such as waste treatment and energy harvesting, aiming to achieve more sustainable and environmentally friendly aquaculture models.
Nevertheless, the development of deep-sea aquaculture cage technology still faces challenges. High costs, complex installation and maintenance, and potential impacts on the deep-sea ecosystem need to be further addressed. Future research and development should focus on optimizing technology, reducing costs, and strengthening environmental protection measures to promote the healthy and sustainable development of deep-sea aquaculture.
