As a core industry ensuring aquatic product supply, aquaculture has long been plagued by the complexity and information opacity of the underwater environment during its large-scale development. Farmers often face a series of challenges, such as difficulty in detecting sudden changes in water quality, poor grasp of biological status, and inadequate supervision of facility safety. These issues not only restrict aquaculture efficiency but also may lead to massive economic losses. However, underwater aquaculture cameras, with their precise sensing, real-time monitoring, and intelligent analysis capabilities, have become key equipment to address these industry pain points.
I. Three Core Difficulties in Underwater Aquaculture
(1) Difficulty in Controlling Dynamic Water Quality and Lagging Risk Response
Water quality is the foundation for the survival of aquaculture organisms, but underwater water quality indicators are constantly changing. In traditional aquaculture, farmers rely on regular manual sampling to test key indicators such as dissolved oxygen, pH value, and ammonia nitrogen. This method has obvious limitations: first, the long sampling interval makes it difficult to capture water quality fluctuations at night or sudden changes (such as a sharp drop in dissolved oxygen caused by massive death of algae on rainy days); second, the testing process is time-consuming. Often, when the test results are available, fish and shrimp have already shown signs of floating or dying due to deteriorating water quality. According to industry statistics, losses caused by delayed water quality monitoring account for more than 30% of total losses.
(2) Difficulty in Grasping Biological Status and Reliance on Experience for Management
The growth, feeding, and disease status of underwater organisms are completely "blind spots". In the feeding process, farmers can only estimate the amount of feed based on breeding density, leading to the contradiction of "insufficient feeding affecting growth and overfeeding polluting water quality". In terms of disease prevention and control, early diseases of fish and shrimp (such as gill lesions and external parasites) are hidden underwater. When obvious symptoms such as abnormal swimming or dark body color are found, the disease has spread to the entire pond, resulting in significantly increased treatment costs and even possible "total collapse". Moreover, information such as the growth rate and size difference of fish and shrimp is difficult to accurately judge, affecting the optimal timing of pond separation and marketing.
(3) Difficulty in Supervising Facility Safety and Hidden Risks Easily Leading to Accidents
The stability of underwater aquaculture facilities is directly related to breeding safety, but real-time monitoring of facility status is difficult under traditional models. In marine cage aquaculture, nets are easily damaged by wind, waves, and marine organisms. Once damaged, fish and shrimp may escape or ferocious fish may break in to prey. If circulating water pipes, oxygenation equipment, etc. in industrial aquaculture are blocked or malfunction, it will lead to stagnation of water circulation and insufficient dissolved oxygen, triggering chain aquaculture accidents. More critically, these facility problems are often not detected in time, and when obvious abnormalities appear, irreversible losses have already been caused.
II. Underwater Aquaculture Cameras: "Intelligent Tools" for Accurately Solving Problems
In response to the above pain points, underwater aquaculture cameras have built a full-chain solution of "sensing - transmission - analysis - early warning" through technological innovation, transforming underwater management from "blind guessing" to "data-driven".
(1) Real-Time Water Quality Monitoring and Early Risk Warning
Underwater aquaculture cameras integrate multi-parameter water quality sensors and high-definition imaging modules to achieve dual "data + image" monitoring of water quality. On the one hand, sensors continuously collect data such as dissolved oxygen, water temperature, turbidity, and ammonia nitrogen 24 hours a day, and synchronize them to the cloud platform through IoT technology. When indicators exceed the preset threshold, the system immediately sends automatic alarms via mobile APP, SMS, etc. Farmers can start oxygenation, water change and other measures immediately to nip risks in the bud. On the other hand, high-definition lenses can intuitively capture visual signals such as changes in water color, plankton aggregation, and sediment churning. For example, dark green water may indicate cyanobacteria blooms. The "visual evidence" under the lens makes the judgment of abnormal water quality more accurate, completely solving the "lag" problem of traditional monitoring.
(2) Full-Process Biological Tracking to Improve Management Precision
With AI algorithms and dynamic tracking technology, underwater aquaculture cameras can accurately grasp the full life cycle status of organisms. In feeding management, the lens can clearly record the feeding intensity and duration of fish and shrimp. The system generates personalized feeding plans by analyzing data to achieve "on-demand feeding", which not only reduces feed costs by 15%-25% but also reduces water pollution caused by residual bait. In disease prevention and control, 4K high-definition lenses can capture 0.1mm-level body surface lesions and abnormal swimming postures (such as side swimming and spinning). Farmers can detect early disease signs through remote terminals, isolate sick fish in time, and use drugs accurately, controlling disease losses within 5%. In addition, cameras can also estimate the average size and population density of fish and shrimp through image recognition technology, providing a scientific basis for pond separation and marketing time, and avoiding "mixed breeding of sizes" affecting growth efficiency.
(3) 24/7 Facility Supervision to Build a Safety Line
The "cruise + fixed-point" monitoring mode of underwater aquaculture cameras provides all-round protection for facility safety. For cage aquaculture, cameras can cruise regularly according to preset trajectories, identify problems such as net damage and excessive attachments through image comparison technology, and automatically generate maintenance reminders. In industrial aquaculture ponds, the lens can focus on key facilities such as oxygenation discs and circulating water pipes, and monitor the operation status of equipment in real time. If oxygenation bubbles decrease or water flow speed slows down, the system immediately triggers an alarm, facilitating staff to troubleshoot faults in time. At the same time, the full-process image data recorded by the camera can be used as a basis for facility maintenance and accident tracing, which is not only convenient for standardizing management processes but also provides a real reference for the optimization of aquaculture technology.
III. Conclusion
From "relying on the weather" to "intelligent aquaculture", underwater aquaculture cameras are profoundly changing the ecological landscape of the aquaculture industry. They not only accurately solve traditional problems such as water quality, biology, and facilities but also promote the transformation of aquaculture models towards intensification and intelligence through integration with AI, IoT, big data, and other technologies. With the continuous iteration of technology, underwater aquaculture cameras will become "standard equipment" for more farmers, providing solid technical support for the high-quality development of the aquaculture industry.
