Abstract
Abstract The influence of rearing rainbow trout (Oncorhynchus mykiss) in water with and without supplemental oxygen on growth, feed conversion, packed red blood cell volume (hematocrit), and survival was determined during a 100-d test with fish fed by self-actuated or demand feeders. Although the rainbow trout reared in oxygen-supplemented water (187% saturation) gained 34% more weight than those reared in control water (95% saturation), variability was high and the difference was not significant (P > 0.14). Supplemental oxygen had no effect on feed conversion and survival. The hematocrit was significantly reduced by supplemental oxygen, but only by 9% – still within the normal range for rainbow trout.
