The fish is sick, SingTown Technology OpenMV knows first.

In aquaculture and ornamental fish management, common diseases such as fish skin diseases, fin and tail rot, and water mold, if not detected in a timely manner, will severely affect the health and survival rate of fish populations. Traditional detection primarily relies on manual visual observation, which is not only inefficient but also susceptible to interference from turbid water, changes in lighting, and fish movement, making it difficult to accurately and promptly assess pathological conditions.

To this end, aquaculture enterprises have adopted SingTown Technology's OpenMV intelligent cameras to establish a machine vision-based fish health monitoring system for real-time identification of abnormalities on fish surfaces. The system is installed on the outer glass walls of fish tanks or aquaculture ponds, capable of monitoring fish activity within a range of 1 meter, and automatically identifying and detecting lesions in small goldfish approximately 5 centimeters in length.

The system aims to detect pathological features such as white spots, white fuzz, water mold, or fin rot on fish surfaces through image recognition, thereby providing early health warnings and assisting breeders in timely intervention.

Aquaculture enterprises have developed a fish health identification system based on the OpenMV smart camera, integrating AI image recognition, color segmentation, texture analysis, and feature comparison algorithms to accurately detect fish body lesions underwater.

The system captures real-time images of the aquarium via a high-definition camera. Edge-side AI utilizes a color recognition algorithm to extract the fish body area and filter out background reflected light. The algorithm then identifies abnormal reflective regions, such as white spots or water mold, by analyzing the brightness distribution and texture continuity on the fish body surface. Simultaneously, the algorithm can assess the presence of fin rot, fin decay, or mold attachment by combining morphological features, such as irregular fin edges, localized whitening, or blurring.

To adapt to fish movement and light fluctuations in water, the system incorporates dynamic threshold adjustment and multi-frame fusion algorithms, enabling stable judgment of consecutive short-term frames and effectively reducing false alarms. During testing, the recognition distance was controlled within 1 meter, and the system can simultaneously identify multiple individuals, achieving an accuracy rate exceeding 92% in detecting water mold disease in small fish such as goldfish. Detection results can be output in real-time to the host computer or APP, with alerts for suspected lesions sent via the network.

SingTown OpenMV intelligent camera is easy to operate, low in power consumption, and strong in real-time detection. It is suitable for deployment on edge devices in aquaculture, pet aquariums, and university research laboratories, helping users achieve timely, visual, and intelligent monitoring of fish health.
