Abstract

Background: Arabian killifish, Aphanius dispar, lives in marine coastal areas of the Middle East, as well as in streams that experience a wide range of salinities and temperatures. It has been used as a mosquito control agent and for studying the toxicities of environmental pollutants. A. dispar's eggshell (chorion) and embryos are highly transparent and are suitable for high resolution microscopic observations, offering excellent visibility of live tissues.

Results: In this study, the staging of normal embryonic development of A. dispar was described and investigated at different temperatures. Embryonic development was then examined under different thermal environments from 26 to 34°C. Our data suggest that temperature has a significant effect on embryonic development, with accelerated development at higher temperatures.

Conclusion: A. dispar exhibits broad thermal tolerance and extended independent feeding capabilities, making it a promising model organism for toxicology and pathogenesis studies conducted over an extended period of time (12 days post-fertilization).

逐阶段探索阿拉伯鳉鱼（Aphanius dispar）的正常胚胎发育。

背景：阿拉伯鳉（Aphanius dispar）生活在中东的海洋沿岸地区，以及盐度和温度范围很广的溪流中。它曾被用作灭蚊剂和研究环境污染物的毒性。悬钩子的卵壳（绒毛膜）和胚胎高度透明，适用于高分辨率显微镜观察，能很好地观察活体组织：结果：本研究描述并调查了不同温度下悬铃木正常胚胎发育的阶段。然后在 26 至 34°C 的不同温度环境下对胚胎发育进行了研究。我们的数据表明，温度对胚胎发育有显著影响，温度越高，胚胎发育越快：结论：A. dispar具有广泛的耐热性和较强的独立摄食能力，因此是一种很有前途的模式生物，可用于较长时间（受精后 12 天）的毒理学和致病机理研究。
