This study developed a portable, low-cost field respirometer for measuring oxygen consumption rates of large-bodied fishes. The respirometer performed well in laboratory tests and was used to measure oxygen consumption rates (MO2 ) of bull sharks Carcharhinus leucas (mean: 249.21 ± 58.10 mg O2 kg-1 h-1 at 27.05 °C). Interspecific comparisons and assessments of oxygen degradation curves indicated the respirometer provided reliable measurements of MO2 . This system presents a field-based alternative to laboratory respirometers, opening opportunities for studies on species in remote localities, increasing the ability to validate physiological field studies.

盒子里的呼吸计：便携式现场呼吸计的开发和使用，用于估计大型鱼类的耗氧量

本研究开发了一种便携式低成本现场呼吸计，用于测量大型鱼类的耗氧率。该呼吸计在实验室测试中表现良好，用于测量牛鲨 Carcharhinus leucas 的耗氧率 (MO2)（平均值：27.05 °C 时为 249.21 ± 58.10 mg O2 kg-1 h-1）。氧降解曲线的种间比较和评估表明，呼吸计提供了可靠的 MO2 测量值。该系统提供了实验室呼吸计的基于现场的替代方案，为偏远地区的物种研究提供了机会，提高了验证生理现场研究的能力。本文受版权保护。版权所有。
