Recently, a lake in a park in Tianjin froze completely due to prolonged cold weather, trapping large numbers of fish beneath the ice—a phenomenon that drew crowds of onlookers. Some visitors even brought tools to break the ice and attempt to retrieve the fish, causing temporary chaos. Park authorities quickly intervened, stopped the unauthorized activity, and urged the public to protect the ecological environment and refrain from disturbing natural features.Experts explained that when lakes freeze in winter, oxygen levels in the water drop, leading some fish to die from suffocation and become encased in ice—an entirely natural occurrence. However, breaking the ice not only risks personal safety by compromising ice integrity but also disrupts the aquatic ecosystem. Moreover, urban park water bodies are often closed or semi-closed systems where fish play a crucial role in maintaining water quality; removing them can trigger secondary issues like algal blooms.Local landscaping authorities have since increased patrols and plan to remove dead fish once temperatures rise to prevent water quality deterioration. They also remind citizens: while marveling at natural phenomena, always follow public regulations and ecological conservation guidelines to jointly preserve urban green spaces.
近日，天津一处公园湖面因持续低温天气完全结冰，冰层下出现大量被冻住的鱼群，引发市民围观。部分游客甚至自带工具凿开冰面，试图将鱼捞出带走，现场一度混乱。对此，公园管理方迅速介入，制止不当行为，并呼吁公众保护生态环境，切勿随意捕捞或破坏自然景观。专家指出，冬季湖面结冰后，水中氧气含量下降，部分鱼类因缺氧而死亡并被冰封，属于自然现象。但人为凿冰不仅可能破坏冰层结构，危及自身安全，还会干扰水体生态平衡。此外，城市公园内的水体多为封闭或半封闭系统，鱼类是维持水质的重要一环，随意捕捞可能造成藻类暴发等次生问题。目前，当地园林部门已加强巡查，并计划在气温回升后对湖中死鱼进行统一清理，防止水质恶化。同时，也提醒市民：欣赏自然奇观的同时，应遵守公共秩序和生态保护规范，共同维护城市绿色空间。
