Haliotis diversicolor is a commercially important cultured shellfish. It is also an important marine model organism for environmental science. High temperature accompanied with hypoxia frequently induces diseases or even death to abalones. In present study, H-1 NMR spectroscopy together with pattern recognition methods was used to investigate the responses of muscle and gill of H. diversicolor to thermal and hypoxic stresses. It was found that obvious gender-, time-and tissue-specificmetabolic responses were induced by thermal and hypoxic stresses. In combination with the changes of H. diversicolor in physiological features, the dual-modal stresses were suggested to mainly cause the disturbance in energy metabolism and osmotic balance in muscle and gill tissues with different mechanisms. Further, the corresponding correlation networks and metabolic pathways derived from the characteristic metabolites were used to assess the major metabolic functions of these characteristic metabolites. These findings shed some lights on the metabolic influences of environmental stresses on marine organisms. (C) 2015 Elsevier B.V. All rights reserved.
