“…The score plots of PLS‐DA (Figure ) indicated that high temperature stress at 29.8°C induced the different metabolites between the thermotolerant strain and the common population which suggested that A. japonicus in the two strains had the different adaptive mechanisms at the metabolic level. Within the 51 metabolites detected with significant difference in concentration, 35 metabolites were significantly higher in group G3 while only 16 metabolites were higher in group C. Most metabolites are associated with energy metabolism or adjusting osmotic pressure (Shao et al., ), which may explain to a certain degree why the thermotolerant A. japonicus strain maintained high activity under high temperatures.…”

“…Carbohydrates and polyols are also energy sources closely associated with energy metabolism (Sartoris, Bock & Portner, ; Wang et al., ). High‐temperature stress can increase muscle glucose content and affect the energy balance in A. japonicus (Shao et al., ). In our previous proteomics analysis, expression of gene in carbohydrate metabolic pathway was significantly changed under heat shock in the intestine of A. japonicus (Xu, Sun, Liu, Zhang & Yang, ).…”

“…Therefore, the population that remains active during aestivation period should have a different metabolic strategy to adapt to high temperature stress (Liu, Zhou et al, 2016). The score plots of PLS-DA ( Figure 4) (Shao et al, 2015), which may explain to a certain degree why the thermotolerant A. japonicus strain maintained high activity under high temperatures.…”

Two groups of Apostichopus japonicus, a thermotolerant strain (group G3: wet weight, 64.22 ± 13.16 g/ind.), which was selected focusing on the performance of thermo‐tolerance through three generations for 10 years, and a control group (group C: wet weight, 62.08 ± 12.01 g/ind.) were collected from July to October in a seawater pond in northern China. Differences in relative faecal mass (RFM), relative intestinal mass (RIM), percentage of individuals with faeces (PIWF) and intestinal metabolites were investigated and compared between the two groups. The temperatures of terminating aestivation of the two groups were assessed according to the values of RFM and RIM. A regression analysis showed that the corresponding group G3 temperatures were 0.56–1.34°C and 0.70–1.49°C higher than those of group C when RFM and RIM were 0.01–0.05 and 0.005–0.025 respectively. The PIWF values in group G3 were 11.5%–21.2% higher than that in group C from 20 July to 22 September. Significant differences at the concentrations of 52 metabolites were detected between the two groups, 36 were higher in group G3 and 16 were higher in group C. The concentrations of threitol, 2‐methylglutaric acid, N‐acetyl‐D‐galactosamine, N‐acetyl‐L‐leucine, lactose, oxoproline, 2,3‐dimethylsuccinic acid and d‐glucoheptose were significantly different between groups G3 and C and were considered metabolic markers distinguishing group G3 from group C. Metabolism of A. japonicus in group G3 was more active than that in group C. These results provide new insight for understanding ingestion and intestinal metabolism in the thermotolerant strain of A. japonicus under high summer temperature.

“…Changes in sea surface temperatures and water pH can enhance the frequency of harmful algal blooms, alter primary productivity, escalate incidences of marine infectious diseases and reduce growth rates and survival of cultured organisms (Burge et al 2014;Glibert et al 2014;Richards et al 2015a,b). Metabolomics has recently been used successfully to investigate the effects of ocean acidification on mussels (Ellis et al 2014) and oysters (Wei et al 2015a,b), thermal stress on mussels (Ellis et al 2014;Dunphy et al 2015) and sea cucumbers (Shao et al 2015) and the interactions between red tideforming dinoflagellates and other phytoplankton species (Poulson-Ellestad et al 2014). We anticipate there will be substantial growth in the application of metabolomics to this research area.…”

Aquaculture production is currently challenged to meet the growing demands for seafood protein throughout the world. To achieve this growth in an efficient, safe and sustainable manner, novel tools and applications will need to be incorporated at each step of the production line. A variety of 'omics' (e.g., transcriptomics, proteomics, metabolomics) applications have already begun to emerge in aquaculture research with extreme success. A promising new 'omics' approach is metabolomics, which aims to use metabolite profiles to identify biomarkers indicative of physiological responses of living samples (e.g., whole organism, tissues, cells) to environmental or culture conditions. One of the benefits of this approach is that it uses a broad scan of biological conditions to identify often unexpected problem or risk areas to focus management attention. In this contribution, we have selected relevant research examples to showcase the applications of metabolomics in aquaculture in four major areas: hatchery production, nutrition and diet, disease and immunology, and food safety and quality. The novelty of this approach is highlighted by the fact that we have cited the majority of published papers in this field, and these are all recent (within the last decade) contributions.

Over the last decade, a wide variety of new foods have been introduced into the global marketplace, many with health benefits that exceed those of traditional foods. Simultaneously, a wide range of analytical technologies has evolved that allow greater capability for the determination of food composition. Nuclear magnetic resonance (NMR), traditionally a research tool used for structural elucidation, is now being used frequently for metabolomics and chemical fingerprinting. Its stability and inherent ease of quantification have been exploited extensively to identify and quantify bioactive components in foods and dietary supplements. In addition, NMR fingerprints have been used to differentiate cultivars, evaluate sensory properties of food and investigate the influence of growing conditions on food crops. Here we review the latest applications of NMR in food analysis. Published 2016. This article is a U.S. Government work and is in the public domain in the USA.
