Dataset for Acanthochromis microplastic lab study 2019

The current study experimentally explored the influence of periodic consumption of polystyrene (PS) microplastic fragments on the body condition and fitness of a tropical marine fish. Adult damselfish, <em>Acanthochromis polyacanthus</em>, were pulse fed microplastic fragments bound with one of two different common plasticizers (DEHP or DEHT) together with virgin-plastic and no-plastic controls. Ingestion of plastic over a 150d period had no detectable effect on growth, indices of body condition, or gonadosomatic indices. Histology of the liver showed no detrimental effects of ingesting any of the plastic treatments on hepatocyte density or vacuolation. Plastic consumption also had no effects on the number of clutches produced over the breeding period, the number of eggs or the survival of the embryos.本研究通过实验探究了周期性摄入聚苯乙烯（polystyrene，PS）微塑料碎片对热带海水鱼类身体状况与生存适合度的影响。实验以成体雀鲷（*Acanthochromis polyacanthus*）为研究对象，采用脉冲投喂方式，分别为其投喂结合了两种常见增塑剂（邻苯二甲酸二(2-乙基己)酯（DEHP）或对苯二甲酸二(2-乙基己)酯（DEHT））的微塑料碎片、纯聚苯乙烯微塑料碎片，并设置无塑料对照组。 为期150天的塑料摄入处理，未对实验鱼的生长、身体状况指标及性腺系数产生可检测的显著影响。肝脏组织学分析结果显示，摄入各实验组塑料样本，均未对肝细胞密度或空泡化造成有害影响。此外，塑料摄入对繁殖期内的产卵批次数量、产卵量以及胚胎存活率亦无显著作用。
