In order to explore the similarities and differences of responses between Hippocampus kuda and Oryzias melastigma, this study analyzed and compared them from the aspects of growth, behavior, physiology, and gene expression. The results showed that H. kuda had a greater impact on its feeding behavior compared to O. melastigma at the same rates. And the continuous responses of enzymes indicated there was a more persistent stress in H. kuda, with stress-related genes like sod1 showing a slower response. Additionally, genes related to sugar and lipid metabolism were significantly different in H. kuda compared to O. melastigma. H. kuda exhibited sensitivity to nearly all treatments, while O. melastigma only responded to treatments of direct input. Furthermore, the responses of immune-related genes in H. kuda were also slower than those in O. melastigma. In summary, the osmotic pressure regulation ability of O. melastigma was more efficient than that of H. kuda in dealing with the stress caused by rapid changes in salinity.
为了探究波纹海马（Hippocampus kuda）和黑点青鳉（Oryzias melastigma）之间反应的异同，本研究从生长、行为、生理和基因表达等方面对它们进行了分析和比较。结果表明，在相同速率下，波纹海马对其摄食行为的影响比黑点青鳉更大。酶的持续反应表明波纹海马存在更持久的应激，与应激相关的基因如sod1反应较慢。此外，与糖和脂质代谢相关的基因在波纹海马和黑点青鳉之间存在显著差异。波纹海马对几乎所有处理都表现出敏感性，而黑点青鳉仅对直接输入的处理有反应。此外，波纹海马中免疫相关基因的反应也比黑点青鳉慢。综上所述，在应对盐度快速变化所引起的应激时，黑点青鳉的渗透压调节能力比波纹海马更有效。
