The acute and joint toxicity test to swordtail fish, Xiphophorus helleri was conducted to evaluate the impact of mercury and selenium on fishes.

用重金属汞(Hg+2)和硒(Se+4)对剑尾鱼进行急性毒性和联合毒性的实验。其目的在于评价水环境中Hg+2和Se+4对鱼类的影响，为制订渔业水质标准提供参考数据。

The HSP70 gene expression was determined in hepatopancreas, spleen, heart and head kidney in green swordtail Xiphophorus helleri challenged by Vibrio alginolyticus 0, 2, 5, 8 and 11 days after administration using RT-PCR. Results showed that tile gene expression of the HSP70 was of tissue specific.

用溶藻弧菌Vibrio alginolyticus感染剑尾鱼Xiphophorus helleri，取感染后第0、2、5、8、11 d的活鱼及感染后第2d濒死鱼，采用半定量RT-PCR方法分别检测HSP70基因在肝胰脏、脾脏、头肾和心脏组织中的表达。

Helleri RR-B strain and the average homozygote rate reached 100%. These loci could be used as markers in genetic monitoring of X. helleri RR-B strain, which had obtained fairly high genetic homozygosity by inbreeding for more than 20 generations.
