Temperature and salinity are key environmental factors for sea cucumber (Apostichopus japonicus) aquaculture. To better understand the molecular regulation mechanisms of A. japonicus under extreme environmental conditions, we collected metabolomic data from a control group (C: 16 °C, 30 salinity), a heat-stress group (HT: 30 °C, 30 salinity), a hypo-salinity group (LS: 16 °C, 20 salinity), and a heat plus hypo-salinity group (...

With the long-term operation of ships, the performance of marine diesel engines gradually declines due to the wear of internal moving components, increasing the risk of potential failures. Fuel consumption is a critical indicator for assessing engine operating conditions, and accurately predicting baseline fuel consumption under normal operating conditions is essential for evaluating ship energy efficiency and conducting fault...
