| 摘 要： | 本研究采用原子吸收分光光度法(AAS)和气相渗透压仪测定了人工养殖美国金鳟和日本鳗鲡精浆的化学组成和渗透压。研究结果表明,Na+、K+是精浆中的主要离子,可能在维持精浆渗透压和精子活动能力中有重要的作用。人工养殖美国金鳟与日本鳗鲡相比,精浆离子含量各项指标除K含量较高之外(P<0.01),其它各项指标均无显著性差异。本实验的两种鱼与其它种类海淡水鱼类比较,各种离子含量均较高;美国金鳟精浆渗透压值与其它鱼类相似,均保持在300 mOsm/kg的水平。

| Abstract: | Atomic Absorption Spectrophotometry(AAS) and gas phase osmometer were conducted to analyse the chemical composition and osmotic pressure of seminal plasma of cultured golden trout and Japanese eel.The results show that sodium(Na~+) and potassium(K~+) were predominant in the seminal plasma,and might play a major role in maintaining the osmotic pressure of the seminal plasma and the viability of the spermatozoa.Potassium was higher in golden trout than in Japanese eel(P<0.01),but there were no significant differences for the other ions.Compared with some species of freshwater and marine fishes,the ionic levels of golden trout and Japanese eel were higher;the osmotic pressure of seminal plasma of golden trout was similar to the other species,and all maintained at 300 mOsm/kg. |
