Abstract

ABSTRACT A study was conducted to investigate the effects of microplastics (<5 mm) and macroplastics (>5 mm) on some phenotypic traits of guppy (Poecilia reticulata). Juvenile male guppies, fed with a commercial diet, were reared for 70 days in aquariums under three different experimental treatments: 1) control (no plastic); 2) microplastic; and 3) macroplastic. The findings revealed that microplastic-treated males had significantly higher mortality, shorter standard length, smaller body area, a limited number of sperm bundles and sigmoid displays, and less sexual interest than macroplastic and no-plastic treated males. The analyses showed no significant variation in tail length, gonopodial thrusts, or different color patterns among the treatments. Taken together, these findings show how microplastic pollution can influence the survival, growth, and reproductive traits of a fish species; this must be considered seriously, as other aquatic animals could be saved by reducing the amount of plastic waste in different aquatic environments.

微塑料的摄入改变了孔雀鱼模型中一些性选择特征的表达(Poecilia reticulata Peters 1859)

摘要研究了微塑料(5 mm)对孔雀鱼(Poecilia reticulata)某些表型性状的影响。以商业饲料喂养的雄性幼鱼在水族馆中饲养了70天，并进行了三种不同的实验处理:1)对照(不使用塑料);2)塑料微粒;3)宏观塑性。研究结果显示，与大塑料和未塑料处理的雄性相比，微塑料处理过的雄性死亡率明显更高，标准长度更短，身体面积更小，精子束和乙状体数量有限，性兴趣更低。分析显示，不同处理间尾长、性腺推力或不同颜色图案无显著差异。综上所述，这些发现表明了微塑料污染如何影响鱼类的生存、生长和生殖特征;这一点必须认真考虑，因为通过减少不同水生环境中的塑料废物量，可以拯救其他水生动物。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
