“…AMPs provide an immediate and rapid immune response in the innate immune system to enhance responses to pathogens [52] . In the case of E. sinensis , the diets added to a mixture of MOS and either β-glucan or inulin significantly increased the expression of Crustin in the hepatopancreas, which suggests the immunostimulant effect of prebiotics on the antibacterial ability of the crabs [46] .…”

“…Additionally, in Chinese mitten crab ( Eriocheir sinensis ) fed with dietary supplementation with either MOS, a mixture of MOS and β-glucan, or a mixture of MOS and inulin, the activities of SOD, glutathione peroxidase (GSH-PX), total antioxidant capacity (T-AOC), alkaline phosphatase, acid phosphatase, lysozyme, PO, and respiratory burst was increased, whereas those of malondialdehyde (MDA) was decreased. This indicates the immunostimulation of the prebiotics in improving antioxidant capacity, preventing oxidative stress, and enhancing non-specific immunity in hosts [46] .…”

“…The expression of genes associated with the signaling pathways is important in evaluating the immunostimulant effects of the supplements. A recent study showed that dietary supplementation with MOS alone or in combination with β-glucan or with inulin promotes the expression of ES-PT, ES-Relish, ES-LITAF, p38MAPK, and Crustin, in E. sinensis [46] . This suggests that prebiotics can stimulate the innate immune system of the crabs through the activation of signaling pathways that link to the PRRs expressed on immune cells.…”

“…Salinity can change the lipid composition of adult Chinese mitten crabs after long-term salinity adaptation (Long et al 2019 ), and Qi et al ( 2020 ) described novel modulation of the physiological regulation mechanism in cultured Chinese mitten crabs in response to consistent salinity changes. Dietary structure and composition also significantly impact the growth, body composition, immunity, and gene expression of Chinese mitten crab (Wei et al 2019a ; Lu et al 2019 ). However, little is known about the effect of alkalinity on intestinal bacteria in Chinese mitten crabs.…”

The Chinese mitten crab (Eriocheir sinensis) is a popular aquaculture product in East Asia, especially in China. In the last decade, rice–crab co-culture has rapidly expanded in China. Under this model, crabs are raised in rice fields instead of in traditional aquaculture ponds. In this study, we cultured two varieties of Chinese mitten crabs (Changjiang and Liaohe) in an alkaline region in northwest China and used Illumina MiSeq sequencing to compare the intestinal bacterial alpha diversity and community structure between traditional and co-culture aquaculture models, between two crab varieties, and between female and male crabs. Significant variations in intestinal bacterial communities were found between crab varieties and between female and male crabs but not between aquaculture models. These results show that rice–crab co-culture operations did not obviously impact the crab intestinal bacterial community compared with traditional pond aquaculture. Firmicutes was the most abundant bacterial phylum in the crab intestines (78%, relative abundance). Three dominant operational taxonomic units (OTUs) represented 73.2% of Firmicutes sequences and 56.8% of all sequences. A dominant OTU assigned as Firmicutes that was negatively correlated with crab body length, width, and weight was found in the source water for the experimental area. The results of this study suggest that the aquaculture of Chinese mitten crabs in alkaline regions requires more study to improve cultivation techniques.

“…In recent years, ecotype aquaculture has rapidly developed, reflecting the overall developmental trend of new agriculture in China. With the development of the food industry, research on the processing of aquatic products has tended to diversify (Lu et al, 2019; Sengor, Alakavuk, & Tosun, 2013; Tang et al, 2013). Aquatic products of different sizes may differ in nutritional quality, which will affect their development and utilization.…”

To provide basic nutritional data and theoretical support for the processing and comprehensive utilization of the Chinese mitten crab, we performed a systematic study of the nutritional components of three edible parts, namely the hepatopancreas, gonads and abdominal muscle, of three groups of animals differing in body mass: 75.55 ± 1.56 g, 100.24 ± 2.04 g and 162.27 ± 3.44 g. The results showed that with a greater body mass, the water content was higher, the protein and ash contents were first higher and then lower, and the fat content was first lower and then higher. Amino acids (AAs), essential AAs (EAAs) and the EAA/AA ratio were first higher and then lower, all reaching the standard for high‐quality protein. The most limiting AA was valine. The EAA index was greater than 97 for all three edible parts of the medium‐sized crabs, indicating that crabs in this size group had very high nutritional value. The numbers of detected fatty acids were the same among the edible parts and the three size groups of the river crabs. Among the mineral elements measured, Ca, K and Na were the most abundant and showed a trend of first being higher and then being lower with a larger crab size. Although heavy metals were detected, the Cr, Pb and Cd levels were all within the permissible limits. Therefore, the nutritional quality of the three edible parts was greater for medium‐sized river crabs than for small and large mitten crabs.
