A review：influence of stocking density on fish welfare

摘要: 养殖密度影响鱼类福利是鱼类生理生态学、福利学和种群生态学研究中的关键问题，已受到各国学者的关注。文章综述了养殖密度影响鱼类福利的主要研究进展，讨论了鱼类死亡率、生长、摄食以及应激反应等福利指标随养殖密度变化的规律及其描述方法；在此基础上，对鱼类福利指标随不同放养密度变化规律的研究以及应用前景进行了展望。

Abstract: Effects of stocking density on mortality, growth, feeding, stress response of fish welfare indexes were summarized in the review．The effect of stocking density on mortality, growth, feeding, stress response varied not only with different fish species, but also with different developmental stages of the same species．
