Reduced water oxygen levels affect maximal feed intake, but not protein or energy utilization efficiency of rainbow trout (Oncorhynchus mykiss)

摘要: This study examined the effect of reduced water oxygen levels on utilization efficiencies energy and protein from a diet fed to rainbow trout. An experimental was at one four ration with an additional starved treatment also included in each oxygenation regime. Oxygen regime varied level, but averaged 9.3 ± 0.36 mg L−1 for normal 5.7 ± 1.4 mg L−1 hypoxia Significant differences were observed apparent satietal feed intake regime, not any pair-fed restricted levels. No significant effects either or by fish. Efficiency use depending significantly affected demonstrates that reduction does affect efficiency dietary digestible trout, result downregulation when fish is
