“…This is probably because of the many natural microorganisms and the presence of growth‐promoting factors with biological activity contained in the bioflocs, including carotene, polyphenols, polysaccharides, taurine and vitamins (Kumar et al, ; Liu, Zhu, Liu, Guo, & Ye, ; De Souza et al, ). These substances promote the growth of farmed animals, improve their anti‐hypoxia function, enhance their ability to withstand oxidative stress and improve their immune systems (Long, Wu, Zhao, Liu, & Cheng, ; Yang, Tian, Liang, Liu, & Huang, ). Another important way in which bioflocs promote antioxidant capability is through the beneficial bacteria, such as Bacillus and Bacteroidetes , contained within them (Cardona et al, ; Ninawe & Selvin, ) .…”

A 60‐day study comparing the growth performance; proximate composition and the digestive, immune and antioxidant enzyme activities of juvenile red swamp crayfish (Procambarus clarkii) reared using biofloc technology (the biofloc group) or a commercial diet (the control group) in zero‐water exchange indoor tanks was performed. A commercial diet was fed to both groups, and the daily feeding amount in the biofloc group was 40% less than that in the control group. Wheat bran and glucose were used in the biofloc group to ensure a C/N ratio >15 and the same feeding energy as that given to the control group. After 60 days of feeding, the final weight, weight gain and specific growth rate in the biofloc group were significantly higher than those in the control group. Furthermore, proximate composition analysis showed that the total hepatopancreatic lipid and ash contents of the biofloc group were significantly higher than those of the control group, and the intestinal and hepatopancreatic pepsin activities in crayfish in the biofloc group were higher than those in crayfish in the control group. Moreover, higher hepatopancreatic lipase and cellulase activities were observed for the biofloc group than for the control group. Biofloc technology promoted the health of the crayfish in terms of their immune and antioxidant enzyme activities. Based on the results of this study, biofloc technology is more effective than traditional commercial diets for the farming of juvenile crayfish.

“…The 6‰ salinity resulted in the lowest hemolymph SOD activity compared to other salinities, suggesting relatively lower level of free radicals in hemolymph of the female E. sinensis under the salinity (Chien et al, 2003 ; Wang et al, 2012 ). Meanwhile, malondialdehyde (MDA) is an indicator of lipid peroxidation, its content often reflects the levels of free radicals and cellular oxidation in tissues (Long et al, 2017a ), both hemolymph and hepatopancrea MDA of the crabs were the lowest at 6‰ as compared to other salinities, again indicating lower peroxide stress in tissues at the salinity.…”

Salinity plays a key role affecting ovarian development, osmoregulation and metabolism of female Chinese mitten crab, Eriocheir sinensis during reproductive migration. In this study, female E. sinensis after their puberty molt were subjected to four salinities of 0, 6, 12, and 18‰ for 40 days to investigate the salinity effects on their ovarian development as well as a range of important physiological parameters. Elevated salinity accelerated the ovarian development with ovigerous crabs found at salinity treatments of 12 and 18‰ despite no copulation had occurred. Meanwhile the survival rate of female crabs showed a decreasing trend with increasing salinity. Higher salinity also led to increased hemolymph Na+, K+, Ca2+, Cl−, and Mg2+ concentrations. The 6‰ treatment had the highest contents of hemolymph total and major free amino acids while the Na+/K+ -ATPase activity in the posterior gills was the lowest among treatments. Total n-3 polyunsaturated fatty acids (∑n-3PUFA) and n-3/n-6 PUFA ratio in the anterior gills showed a decreasing trend with salinity while 18‰ had the highest ∑PUFA and ∑n-6PUFA. The ∑n-3PUFA content and n-3/n-6 PUFA ratio of the posterior gills showed a fluctuating pattern and the highest value was detected at 0‰, while an increasing trend was found for the ∑n-6PUFA with increasing salinity. The hemolymph glucose showed a decreasing trend with increasing salinity and the highest total cholesterol in hemolymph was detected at 12‰. The 18‰ treatment had the highest levels of hemolymph γ-glutamyltransferase, alkaline phosphatase and acid phosphatase, as well as glucose, urea and acid phosphatase in hepatopancreas while the highest hemolymph superoxide dismutase and malondialdehyde were detected at 0‰. Overall, the results showed that salinity increase from freshwater to brackish conditions led to lower metabolism, accelerated ovarian development, and the appearance of ovigerous crabs without copulation in female E. sinensis post puberty molt.

“…Nutritional indices can reflect the physiological status and metabolism of crustaceans and were generally affected by dietary nutrients (Long, Wu, et al., 2017; Ma et al., 2017). For lipid metabolism, previous studies have demonstrated that appropriately higher dietary total lipid content could increase the lipase (LPS) activity in the hepatopancreas of juvenile E. sinensis (Yang et al., 2011, dietary lipid content: 10.07% dry diet), juvenile mud crab Scylla paramamosain (Xu et al., 2017, dietary lipid content: 8.14% dry diet) and juvenile red claw crayfish Cherax quadricarinatus (Lu et al., 2018, dietary lipid content: 7% dry diet), but excessive dietary total lipid content would inhibit the LPS activity.…”

“…By contrast, formulated diets have many advantages, such as balanced nutrition, controllable quality and supply, convenient storage, reasonable price, and links with improvement of breeding performance and nutritional quality of E. sinensis . Formulated diets have been popularized and applied in production (He et al., 2016; Long, Wu, Zhao, Liu, & Cheng, 2017; Zhuang et al., 2016). Therefore, the expansion of the E. sinensis aquaculture industry relies on the development and adoption of advanced formulated diets (Chen & Li, 2009; Cheng, Wu, & Li, 2018).…”

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.
