Zebrafish is one of the world's most widely used laboratory species, and it is utilized to answer important research questions in disparate fields such as biomedicine, genetics, developmental biology, pharmacology, toxicology, physiology, and evolution. Despite their popularity, very little is known about the biology of zebrafish in their natural habitat. This may, in part, be due to the difficulties associated with undertaking field trips to the remote areas of northern India, Nepal, and Bangladesh, which is the natural distribution range of zebrafish. Here, we present a field report describing a recent trip where we, together with local collaborators, visited several rivers in West Bengal, India, to observe wild zebrafish and their habitat. We present an overview of our observations on the biology of wild zebrafish, and the great variability of the different environments where they were found. We also include data collected on water chemistry parameters at 12 zebrafish sites, and weight data and photos of fish from these sites. We present extensive underwater videos of wild zebrafish and photographs of the sites, including video footage of courtship behavior. We show that the breeding period of wild zebrafish can be extended from the previous record of April-August to April-October. In addition, we provide practical advice for future zebrafish expeditions to this rural and inaccessible area. The goals of this article are to shed some light on the ecology of wild zebrafish, and to facilitate scientists in their future research trips. We hope that by observing zebrafish in the wild, we can increase our understanding of the natural ecology of this important model organism.

关于印度野生斑马鱼(Danio rerio)的观察。

斑马鱼是世界上使用最广泛的实验室物种之一,被用来回答不同领域的重要研究问题,例如生物医学,遗传学,发育生物学,药理学,毒理学,生理学和进化。尽管它们很受欢迎,但关于斑马鱼在其自然栖息地中的生物学知之甚少。这可能部分是由于与前往印度北部,尼泊尔和孟加拉国(这是斑马鱼的自然分布范围)的偏远地区进行实地考察有关的困难。在这里,我们提供了一份现场报告,描述了最近的一次旅行,我们与当地合作者一起访问了印度西孟加拉邦的几条河,以观察野生斑马鱼及其栖息地。我们概述了我们对野生斑马鱼生物学的观察,以及发现它们的不同环境的巨大差异。我们还包括在12个斑马鱼站点收集的水化学参数数据,以及这些站点的体重数据和鱼的照片。我们展示了野生斑马鱼的水下录像和现场照片,包括求爱行为的录像。我们显示野生斑马鱼的繁殖期可以从以前的4月-8月记录延长到4月-10月。此外,我们为将来斑马鱼远征农村和人迹罕至的地区提供实用建议。本文的目的是阐明野生斑马鱼的生态,并为科学家今后的研究之旅提供便利。我们希望通过在野外观察斑马鱼,
