Gene expression profiles of gill provide insights into the aerial respiration capacity of the Chinese mitten crab, Eriocheir sinensis

Genome-Wide Identification, Characterization, and Expression Analysis of DDE_Tnp_4 Family Genes in Eriocheir sinensis

“…Under stress conditions, the profiles of DDE_Tnp_4 family genes were analyzed using transcriptome data obtained from previous studies [ 5 ] and the European Nucleotide Archive (ENA) database. During acute high salinity stress experiment, healthy crab individuals were divided into four groups; one group in freshwater serves as the control, and other three groups were challenged with 16‰, 28‰, and 35‰ saltwater, respectively.…”

“…E. sinensis is a euryhaline species and a strong osmoregulator as they can function equally well in freshwater or brackish environments [ 4 ]. In addition, E. sinensis is a species capable of aerial respiration and can survive for extended periods of time, even days, without water [ 5 ]. Compared with Scylla paramamosain and Portunus trituberculatus , which are also commercially important crustaceans in China, E. sinensis exhibits enhanced tolerance to abiotic factors, including high salinity and air exposure [ 2 , 5 , 6 , 7 ].…”

Existing studies have revealed that strong tolerance to high salinity and air exposure of E. sinensis is linked to genes participating in innate immune system and many other physiological activities [ 8 , 9 ], such as Toll-like receptor (TLR), Na + -K + -ATPase, heat shock proteins (like Hsp70 and Hsp90), and superoxide dismutase (SOD) [ 10 , 11 , 12 ].…”

An oxygen‐releasing tablet to reduce the hypoxia‐induced damage of Chinese mitten crabs ( Eriocheir sinensis )

“…However, most recent studies have focused on the farming and processing of E. sinensis, but the transportation was ignored. A common method of transportation is eight to ten E. sinensis stacked in a foam box (e.g., 25 cm × 10 cm × 25 cm) with some ice packs, but this method will cause a lack of oxygen and cause severe adverse effects on the E. sinensis (Chen et al, 2019).Oxygen is considered to be one of the most important environmental factors during the transportation of E. sinensis, while hypoxia caused the depression of metabolic rate and the change of physiological functions of crabs, which resulted in poor health and great economic loss of crabs (Gravinese et al, 2020;de Lima et al, 2021;Okamura et al, 2018). Recently, the mechanical aeration and chemical oxygen generator have been used to increase the oxygen content…”
