Abstract In aquaculture, fish are exposed to unavoidable stressors that can be detrimental for their health and welfare. However, welfare in farmed fish can be difficult to assess, and, so far, no standardized test has been universally accepted as a welfare indicator. This work contributes to the establishment of behavioural welfare indicators in a marine teleost in response to different water quality acute stressors. Groups of ten fish were exposed to high Total Ammonia Nitrogen concentration (High TAN, 18 mg.L-1), Hyperoxia (200 % O2 saturation), Hypoxia (20 % O2 saturation), or control water quality (100% O2 saturation and TAN

空间分布和活动模式作为福利指标响应欧洲鲈鱼，Dicentrarchus labrax 的水质变化

摘要 在水产养殖中，鱼类面临不可避免的压力，这可能对其健康和福利有害。然而，养殖鱼类的福利可能难以评估，到目前为止，还没有标准化测试被普遍接受为福利指标。这项工作有助于在海洋硬骨鱼中建立行为福利指标，以应对不同的水质急性压力源。十条鱼一组暴露于高总氨氮浓度（高 TAN，18 mg.L-1）、高氧（200% O2 饱和度）、缺氧（20% O2 饱和度）或控制水质（100% O2 饱和度和谭
