Fish Respiratory Rate (Gill Opening / Closing) Monitor | 鱼类呼吸频率（鳃盖开合）监测
v1.0.0Through fixed cameras on aquariums, the system analyzes fish gill-cover opening / closing motion video, detects periodic gill opening and closing, and calculates respiratory rate (breaths per minute). When the respiratory rate exceeds a normal threshold (e.g. > 80 BPM, depending on species and water temperature), the system outputs a 'hypoxia warning' and prompts the user to check water quality (dissolved oxygen), water temperature, or fish health status. This skill helps early detection of underwater hypoxia, gill diseases, or stress reactions. Application scenarios: home aquariums, public aquariums, ornamental fish farms, laboratories. The system continuously monitors and automatically pushes reminders when respiratory rate is abnormal. Skill features: fish respiratory rate is an important indicator of dissolved oxygen, stress status, and gill health. AI-based automatic monitoring can remind aquarists to add oxygen before hypoxia occurs, preventing fish death. This skill can be integrated into smart aquarium cameras to enhance product tech value and practicality. | 通过鱼缸固定摄像头，分析鱼类的鳃盖开合运动视频，检测鳃盖的周期性开启和闭合，计算呼吸频率（次/分钟）。当呼吸频率超过正常阈值（例如 > 80 次/分钟，具体依品种和水温而定）时，输出'缺氧预警'，提示用户检查水质（溶氧量）、水温或鱼的健康状态。该技能有助于早期发现水中缺氧、鳃部疾病或应激反应。应用场景：家庭鱼缸、水族馆、观赏鱼养殖场、实验室。系统连续监测，在呼吸频率异常时自动推送提醒。技能特点：鱼类呼吸频率是反映溶氧量、应激状态和鳃部健康的重要指标。通过 AI 自动监测，可在缺氧发生前及时提醒养鱼者增氧，防止鱼只死亡。该技能可集成到智能鱼缸摄像头中，提升产品科技含量和实用性。
