Respiration and low oxygen tolerance of two fish species from the Arabian Sea, Cubiceps whiteleggi and Coryphaena hippurus

Respiration and low oxygen tolerance of two fish species from the Arabian Sea, Cubiceps... Summary During the 1987 cruise of F.S. Meteor in the Arabian Sea, respiration rates and effects of low oxygen saturation on behaviour and respiration have been investigated in two fish species. Cubiceps whiteleggi is an inhabitant of the partly oxygen‐depleted epipelagic zone. It is more tolerant to oxygen shortage than the second species, Coryphaena hippurus. At naturally occuring temperatures, first response to low oxygen was noted at values slightly below air saturation in C. hippurus and at 20–30% oxygen saturation in C. whiteleggi. After exposure to low oxygen saturation, the reaction patterns were completely different for the two species, reflecting the particular requirements of their living space. In C. hippurus lethal oxygen saturations seemed to be reached just below 60% oxygen saturation. In C. whiteleggi first mortality occurred at 10% oxygen saturation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

Summary During the 1987 cruise of F.S. Meteor in the Arabian Sea, respiration rates and effects of low oxygen saturation on behaviour and respiration have been investigated in two fish species. Cubiceps whiteleggi is an inhabitant of the partly oxygen‐depleted epipelagic zone. It is more tolerant to oxygen shortage than the second species, Coryphaena hippurus. At naturally occuring temperatures, first response to low oxygen was noted at values slightly below air saturation in C. hippurus and at 20–30% oxygen saturation in C. whiteleggi. After exposure to low oxygen saturation, the reaction patterns were completely different for the two species, reflecting the particular requirements of their living space. In C. hippurus lethal oxygen saturations seemed to be reached just below 60% oxygen saturation. In C. whiteleggi first mortality occurred at 10% oxygen saturation.
