Abstract

A highly significant linear correlation was found between glomerular filtration rate and urine flow rate in both freshwater and seawater trout. The percentage tubular reabsorption of water was approximately 33% greater in seawater trout than in freshwater trout. 2. As oxygen consumption increased, the urine flow rate increased in freshwater and seawater rainbow trout. The proportional increase in urine flow with incremental changes in oxygen consumption was approximately the same in fresh water and sea water. 3. A significant positive linear relationship between oxygen consumption and glomerular filtration rate was found in both salinities. The proportional increase in GFR with incremental changes in the oxygen consumption rate was higher in the seawater trout than in the freshwater trout. 4. As oxygen consumption increased, the percentage tubular reabsorption of water decreased in the freshwater trout. No significant relationship between these two factors was found in the seawater trout.

摘要

在淡水虹鳟和海水虹鳟中，肾小球滤过率与尿流率之间均发现高度显著的线性相关性。海水虹鳟的肾小管对水的重吸收百分比比淡水虹鳟大约高33%。2. 随着耗氧量增加，淡水虹鳟和海水虹鳟的尿流率均增加。淡水和海水中，尿流率随耗氧量的增量变化而成比例增加的情况大致相同。3. 在两种盐度条件下，均发现耗氧量与肾小球滤过率之间存在显著的正线性关系。海水虹鳟中，肾小球滤过率随耗氧率的增量变化而成比例增加的幅度高于淡水虹鳟。4. 随着耗氧量增加，淡水虹鳟肾小管对水的重吸收百分比降低。在海水虹鳟中未发现这两个因素之间存在显著关系。
