Fish Gasping & Ammonia Poisoning Visual Warning | 水族箱内氨氮中毒视觉预兆（鱼浮头）
v1.0.0Through fixed aquarium cameras, the system analyzes fish behavior near the water surface, detecting repeated mouth-out-of-water (gasping), rapid mouth opening/closing (fast respiration) and exaggerated operculum (gill cover) movement — classic symptoms of hypoxia or poisoning. When multiple fish exhibit the above behavior simultaneously and the duration exceeds a configurable threshold (default 60 seconds), the system outputs an 'ammonia poisoning or hypoxia risk warning', prompting the user to immediately test water quality, perform water change, or increase aeration. This skill helps take emergency action BEFORE fish die. Application scenarios: home aquariums, public aquariums, aquaculture ponds. The system monitors in real time and pushes alerts the moment fish gasping is detected. Skill features: ammonia poisoning is a common acute emergency in aquariums — by the time it is noticed, fish deaths may have already occurred. AI-based automatic recognition of gasping and abnormal respiration provides emergency warning at the earliest stage, buying time to handle the situation and reduce losses. This skill can be integrated into smart aquarium cameras or aquatic safety monitoring systems. | 通过鱼缸固定摄像头，分析鱼类在水面附近的行为，检测鱼嘴反复探出水面（浮头）、张口快速开合（类似喘气）、鳃盖运动加剧等缺氧或中毒典型症状。当多条鱼同时出现上述行为且持续时间超过设定阈值（默认 60 秒）时，输出'氨氮中毒或缺氧风险预警'，提醒用户立即检测水质、换水或增氧。该技能有助于在鱼只死亡前采取紧急措施。应用场景：家庭鱼缸、水族馆、养殖池。系统实时监测，一旦发现鱼浮头立即推送警报。技能特点：氨氮中毒是鱼缸常见急症，往往在检测到前已造成鱼只死亡。通过 AI 自动识别鱼浮头和异常呼吸，可在事发初期紧急提醒，为处理争取时间，减少损失。该技能可集成到智能鱼缸摄像头或水族安防系统中。
