罗非鱼（Oreochromis spp.）对世界各地的水产养殖生产具有巨大潜力。罗非鱼生产商对产量更高的品种和能在高盐水中生存的鱼的需求越来越大。新品种和一致的原种是可持续水产养殖的关键目标，但在这些必要的目标方面仍然没有足够的进展。因此，本研究描述了癍点奥利亚非鲫的基因组序列，为罗非鱼海水养殖提供支持。基因组草图为0.768 Gb（千兆字节），支架N-50（基因组（50%）为该长度的片段）为0.22 Mb（兆字节）。GC含量为40.4%，杂合率为0.35%，重复率为47.97%。在O.斑点虫基因组预测的抗菌肽为262个，为进一步的研究带来了新的希望。这一全基因组序列为生物医学和分子研究提供了新的见解，也将改善罗非鱼的高产、抗病和适应盐水的育种。
Tilapia (Oreochromis spp.) have significant potential for aquaculture production around the world. There is an increasing demand among tilapia producers for strains with higher yields and for fish that can survive in highly saline water. Novel strains and consistent seedstock are critically important objectives for sustainable aquaculture, but for these required targets there is still not enough progress. Therefore, this study describes the genome sequence of Oreochromis spilurus to support the seawater culture of tilapia. The draft genome is 0.768 Gb (gigabases), with a scaffold N-50 (the genome (50%) is in fragments of this length) of 0.22 Mb (megabases). The GC content is 40.4%, the heterozygosity rate is 0.35%, and the repeat content is 47.97%. The predicted protein-coding peptide encoded 51,642 and predicted 10,641 protein-coding genes in the O. spilurus genome. The predicted antimicrobial peptides were 262, bringing new hope for further research. This whole genome sequence provides new insights for biomedical and molecular research and will also improve the breeding of tilapia for high yields, resistance to disease, and adaptation to salt water.
