Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and more particularly to a control system for industrialized recirculating aquaculture of sea urchins. Background Technology

[0002] Sea urchins are a precious marine organism, their gonads possessing a delicious flavor and rich in EPA and other highly unsaturated fatty acids, giving them extremely high nutritional and economic value. In recent years, with the increasing demand for fresh sea urchins, the sea urchin farming industry has developed rapidly. Sea urchin farming not only provides the market with abundant seafood but also provides important support for the economic development of coastal areas. The growth and reproduction of sea urchins have high requirements for environmental conditions such as water quality, temperature, and dissolved oxygen; a suitable farming environment can promote the healthy growth of sea urchins and improve their yield and quality.

[0003] Currently, sea urchin farming mainly includes bottom seeding and raft culture. Bottom seeding involves releasing sea urchin seedlings onto the seabed and allowing them to grow naturally; raft culture involves placing sea urchin seedlings on rafts for cultivation. In addition, intensive aquaculture, as an emerging farming model, is gradually developing. In intensive aquaculture, sea urchins are cultivated in specialized tanks, and their growth is promoted through artificial control of water temperature, water quality, and other conditions. However, both traditional bottom seeding, raft culture, and existing intensive aquaculture methods face some pressing problems that need to be addressed.

[0004] Traditional bottom-seeding and raft culture methods have many drawbacks. First, the culture environment is uncontrollable. Sea urchin growth largely depends on natural marine conditions, such as water temperature and quality. Harsh environments, such as excessively high or low temperatures or water pollution, severely impact their growth and survival. Second, the operation is complex. Raft culture requires regular feeding, and workers cannot operate in rough seas, increasing the difficulty and cost. Furthermore, harvesting is challenging. Bottom-seeding requires diving for harvesting, which is both costly and inefficient; raft culture harvests in large quantities, making sorting by size and grade difficult. Finally, sea urchins are highly seasonal, available only for one or two months of the year, making year-round supply impossible.

[0005] While existing industrialized sea urchin farming methods can improve growth efficiency through artificially controlling the farming environment, several problems exist. Large amounts of sea urchin feces accumulate at the bottom of the tanks. If this organic matter remains in the water for extended periods, it leads to elevated levels of harmful chemicals such as ammonia nitrogen and nitrite, while simultaneously reducing dissolved oxygen, thus hindering normal sea urchin growth and even threatening their survival. Currently, conventional methods involve frequent water changes or using flow-through aquaculture to remove the feces, but both methods require significant manpower and resources. Furthermore, directly discharging sea urchin feces into the sea not only wastes resources but also pollutes nearshore waters. Summary of the Invention
