在鲈鱼Perca fluviatilis和现有的信息，在各种盐度的硬骨鱼类的摄氧量的影响，盐度对静息摄氧量进行了测定。逆着浓度梯度的跨上皮离子运输需要能量，并且暴露于与体液完全不同的盐度，因此施加了能量需求，与淡水和海水相比，预期该能量需求在微咸水中最低。在各个物种中，氧摄取量和盐度之间没有明显的趋势，对渗透和离子调节成本的估计从标准代谢的百分之几到>30%不等。
The effect of salinity on resting oxygen uptake was measured in the perch Perca fluviatilis and available information on oxygen uptake in teleost species at a variety of salinities was reviewed. Trans-epithelial ion transport against a concentration gradient requires energy and exposure to salinities osmotically different from the body fluids therefore imposes an energetic demand that is expected to be lowest in brackish water compared to fresh and sea water. Across species, there is no clear trend between oxygen uptake and salinity, and estimates of cost of osmotic and ionic regulation vary from a few per cent to >30% of standard metabolism.
