“…In addition, FDs also have advantage of easy storage, have less impact on water quality, and have the ability to supplement relatively complete nutrients at each period of crab growth. Therefore, FD feeding mode has become a trend for the Chinese mitten crab farming (Que and others ).…”

To reveal the impact of different feeding modes on the flavor quality of female Chinese mitten crab (Eriocheir sinensis) this study was conducted to compare the sensory evaluation scores, flavor compounds in meat and hepatopancreas of female E. sinensis fed with 3 feeding modes, that is, natural diets (NDs), traditional diets (TDs), and formulated diets (FDs). The result showed that crabs fed with ND had significantly lower sensory scores than the other 2 feeding modes in both edible tissues. The odor and taste profiles were evaluated by Electronic nose (E-nose) and tongue (E-tongue) techniques, respectively; results of perchloric acid showed each edible tissue had significant differences among the 3 modes. Contents of volatile compounds were measured by Headspace-solid phase micro extraction combined with gas chromatography-mass spectrometer. A total of 35 and 44 volatile compounds were identified in meat and hepatopancreas, respectively. ND mode of meat had the highest relative odor activity value (ROAV) summation among the 3 diet modes. TD mode of hepatopancreas had significantly higher ROAV summations. Based on the analysis of free amino acids and 5'-nucleotides, nonvolatile compounds were evaluated by equivalent umami concentration (EUC) and taste active values (TAVs) methods. For both meat and hepatopancreas, TD had the highest contents of umami amino acid, as for the 5'-nucleotide, FD had the highest 5'-inosin monophosphate concentrations. Overall, the EUC and TAVs of TD were higher than that of FD, whereas ND mode had the lowest values in the 2 edible tissues. In conclusion, TD mode had the best performance in terms of sensory evaluation, ROAVs of aroma-active compounds, and nonvolatile active compounds.

“…Due to different nutritional combinations that may affect the quality of crabs as a result changes in fatty acids, most culturists prefer to use trash fish feed. However, Que et al (2012) proved that formulated feed could replace frozen trash fish feed and meet the nutritional requirements of Chinese mitten crabs, as there was no significant effect on the survival and growth rates or reproduction when the formulated feed was substituted for frozen trash fish during the aquaculture process (Que et al 2012). Therefore, the formulated feed provides only basic growth requirements, and has the potential to reduce the nutritional and commercial value of Chinese mitten crabs.…”

“…In addition, formulated feed can increase the viability of juvenile Chinese mitten crabs and promote gonadal development (Wu et al 2011). Previous studies showed that different types of feed affected the water content, crude protein content, total lipid, and other biochemical components in the hepatopancreas, gonads and muscles of Chinese mitten crabs (Ge et al 2017;Que et al 2011Que et al , 2012. In general, substituting the frozen trash feed is feasible to some extent, but it is necessary to study the formula composition of formulated feed to meet the product quality requirement.…”

In this study, the effects of different feeds on fatty acid composition in the Chinese mitten crab (Eriocheir sinensis) were investigated. The fatty acid composition in the Chinese mitten crab was significantly correlated with the type of feed source provided. Differences between the feed groups pertained mainly five fatty acids: oleic acid, linoleic acid, palmitic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The content of EPA and DHA was higher in the group of frozen trash fish than in the group of formulated feed. On the other hand, the content of oleic acid, linoleic acid and palmitic acid was higher in the formulated feed group than in the frozen trash fish group. There were significant differences in the nutritional value of the Chinese mitten crab reared under different feed sources, i.e. Chinese mitten crabs reared with the frozen trash fish feed were larger than those reared with the formulated feed, especially as regards the ω-3/ω-6 PUFA ratio and essential fatty acid levels.

“…Ingredients for traditional or natural diets can have several problems, including instability of supply, unbalanced nutrition and the potential to harbour pathogens. These problems can lead to early crab gonad development, small sized adult crabs, deterioration of pond water quality, increased disease outbreak and poor quality of adult crabs (Que et al., 2012; Wang, Wang, & Ma, 2013). Therefore, the health and sustainable development of the aquaculture industry of E. sinensis has been seriously restricted.…”

“…Several studies have investigated the replacement of traditional or natural diets by commercial formulated diets for juvenile E. sinensis , with a focus on survival, gonad development (Pan, Xiao, Zhang, & Luan, 2005), growth performance, digestive physiology (Yang, Yang, Zhao, Fan, & Chen, 2011; Yang et al., 2013), immune and disease resistance (Jiang et al., 2017) and biochemical composition (Que et al., 2012). However, fewer studies have investigated adult crabs, where only the effects of the different diets on growth performance, cost or nutritional quality have been investigated (Pan et al., 2016; Zhuang et al., 2016).…”

Natural and traditional diets have been gradually replaced with formulated diets for the Chinese mitten crab Eriocheir sinensis culture, but it is unclear what effects different feeding modes have on digestive physiology and metabolism of E. sinensis. This study investigated the effects of three feeding modes, formulated diets (FD), natural diets (ND, trash fish and freshwater snails) and traditional diets (TD, soybean, wheat, broad bean and corn) on digestive enzyme activity, physiological indices and metabolomics of adult female E. sinensis. The ND had the highest activities of trypsin and lipase in the hepatopancreas, while the highest amylase activity was detected in TD. The highest content of hepatopancreas triglyceride was detected in FD, while the highest levels of lipoprotein lipase, hepatic lipase, lactic acid, malonaldehyde, acid phosphatase and alkaline phosphatase in the hepatopancreas, as well as the total cholesterol, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol and γ‐glutamyltransferase in serum were detected in ND. The TD had the highest content of glucose and uric acid in the hepatopancreas as well as the free cholesterol, lactic acid, aspartate aminotransferase and alanine aminotransferase in the serum. The metabolomics showed that most differential metabolites involved in amino acid anabolism in serum and hepatopancreas were significantly up‐regulated in FD. The metabolites involved in energy metabolism and gluconeogenesis in the hepatopancreas were significantly down‐regulated in FD. These results suggested that feeding with formulated diets promotes amino acid synthesis and reduces energy metabolism, which leads to more protein and glucose deposition in tissue.
