Subadult teleosts, Tilapia zilli and Clarias lazera, were exposed in laboratory bioassays to lethal and sublethal concentrations of zinc, seasonally (at range of temperature between 9.3 +/- 1.5 and 25 +/- 1 degree C). It appears that Tilapia is more susceptible to Zn than Clarias and both species are more resistant to Zn toxicity at lower temperature (during winter). To determine the uptake and tissue distribution of Zn in the two species, gill, liver and muscles were analysed at moderate temperature (during spring). After a 96 hr exposure period, Zn was decreased in the following order: gill greater than liver greater than muscle.
将亚成体硬骨鱼尼罗罗非鱼和胡子鲶置于实验室生物测定中，使其季节性地暴露于致死和亚致死浓度的锌中（温度范围在9.3±1.5至25±1摄氏度之间）。尼罗罗非鱼似乎比胡子鲶对锌更敏感，并且两个物种在较低温度（冬季）下对锌毒性的耐受性更强。为了确定这两个物种对锌的摄取和组织分布，在中等温度（春季）下对鳃、肝脏和肌肉进行了分析。经过96小时的暴露期后，锌含量按以下顺序降低：鳃＞肝脏＞肌肉。
