“…There is no doubt that the feeds have a positive effect on the growth and immunity of crabs. Our previous work also found that feeds (Melatonin added) have a strong immune regulation and anti-stress effect on crabs (Song et al, 2021;Yang et al, 2021;Zhang et al, 2019b). However, it is not clear whether single factor feeds have an impact on E. nuttallii and water quality.…”

“…At present, many studies have confirmed that melatonin (MT) can improve plant resistance and regulate seed germination, seedling growth, flowering and senescence in many plants (Wang, Sun, Chang, et al, 2013;Zhang et al, 2014Zhang et al, , 2015. It has been also shown that MT supplementation in feeds causes a wide range of positive effects in E. sinensis, including survival, immune response, digestive function and gut microbiota in E. sinensis (Song et al, 2021;Yang et al, 2021;Zhang et al, 2019b). However, there is a lack of research on the effects of MT feeds on physiological indexes of aquatic plants.…”

“…Therefore, we studied whether feeds directly affected E. nuttallii and water quality in laboratory conditions. In addition, our previous studies have shown that melatonin supplementation in feeds protects E. sinensis from oxidative damage and immune system caused by acute hypoxia, ammonia‐N toxicity and deltamethrin (Song et al, 2021; Yang et al, 2021; Zhang et al, 2019b). Therefore, we also studied the effect of feed type (whether MT was added to the feed) on E. nuttallii and water quality in this experiment.…”

In the ecological culture of the Eriocheir sinensis in China, the coexistence of feeds fed for crabs and Elodea nuttallii is a common pattern in ponds. The objective of this study, for the first time, was to evaluate the effects of feeds (Melatonin added) on E. nuttallii growth and water quality under the artificial cultivation condition and avoid the influence of complex ecological factors. According to the characteristics of E. nuttallii growth, the optimum culture conditions (light intensity, branch type and culture time) were firstly explored in the laboratory and then chosen as culture conditions for feed experiment. The results showed that the 4500lux, Branch I (with about 1 cm visible branch), and 14-day culture were selected as the optimum E. nuttallii culture conditions in the laboratory. Fresh weight, weight growth rate, relative growth rate and height in MT feeds group were significantly higher than those in the basic feeds and no feeds groups (p < 0.05). Chlorophyll b contents in the MT feeds group were significantly higher than that in the basic feeds group (p < 0.05). Total nitrogen, total phosphorus, ammonia nitrogen and nitrite nitrogen contents in MT feeds group were not significantly higher than that in the basic feeds group (p > 0.05). The results indicated that residual feeds containing melatonin in crab ponds boost the growth of E. nuttallii to some extent and without negative effects on water quality. The results will help to lay a foundation for clarifying the relationship between feeds and aquatic plants and water quality in E. sinensis aquaculture.

“…If external stress exceeds the body’s tolerance, then the cell eventually goes to the apoptotic pathway. Relevant research has been reported in fish [ 16 ], shrimp [ 17 , 18 ], and crabs [ 19 , 20 ] that the body responds to external environmental stresses by regulating its own immune system. Heat shock protein (HSP) are a highly conserved protein family that maintain cellular homeostasis and play an important role in the early stage of the low-temperature-tolerance mechanism in fish [ 21 , 22 ].…”

High nutritional value and the development of efficient biotechnological methods of controlled production have made black porgy (Acanthopagrus schlegelii) an economically important fish in Chinese aquaculture in recent years. However, aquaculture production of the species faces multiple issues associated with reduced growth rate, low reproduction ability, and high mortality during production, which are associated with the species’ limited tolerance to low temperatures. To date, comprehensive information on the genetic-based mechanisms of cold tolerance and adaptation to low temperature in the species are still unavailable. In this study, the HiSeq™2500 (Illumina) sequencing platform was used to analyze the transcriptomic profile of the liver tissue in the black porgy subjected to different extents of cold shock, including a control temperature group (AS, T = 15 °C), an intermediate temperature group (AL1, T = 10 °C), and an acute low-temperature stress group (AL2, T = 5 °C). For this purpose, three standardized cDNA libraries of AS, AL1, and AL2 were established. We obtained 43,258,908, 48,239,072, and 38,983,833 clean reads from the AS group, AL1 group, and AL2 group, respectively. After pairwise comparison, 70 differentially expressed genes (DEGs) were identified in the examined fish groups. Among them, 60 genes were found to be significantly differentially expressed after trend analysis. GO annotation and enrichment results showed that they were mainly enriched into three categories: biological processes (12 subcategories), molecular functions (7 subcategories), and cellular components (7 subcategories). KEGG analysis results indicated that all significantly differentially expressed genes were annotated to 102 signaling pathways, including biological rhythm, cholesterol metabolism, glycerolipid metabolism, animal autophagy, FoxO signaling pathway, steroid biosynthesis, and regulation of adipocyte lipolysis and apoptosis. Four of them, namely: G6PC, GPX1, GCK, and HSPE1 were randomly selected for further qRT-PCR verification of data reliability obtained by RNA-Seq technology. In this study, we found that environmental acute cold stress mainly affected the black porgy’s biological processes related to metabolism, apoptosis, and signal transduction. The data that we have reported provides baseline information for further studies concerning the genetic responses of the black porgy under cold stress conditions, the improvement of its aquaculture production, and other economically important matters regarding their limited tolerance to cold shock.

“…130 Previous studies have also found that a ratio of 1/2 docosahexaenoic acid/eicosapentaenoic acid and melatonin (about 50 mg/kg) in feed is beneficial to the immunity, physiology and hypoxic stress resistance in juvenile E. sinensis. 131,132 Thus, control of nutrient delivery can be an effective way to help alleviate the adverse effects of hypoxic stress on decapod crustaceans.…”

Crustaceans are often exposed to hypoxic stress in intensive aquaculture systems. Such stress leads to physiological, behavioural and biochemical changes, which can cause various metabolic disorders or even death. Crustacean response mechanisms to hypoxia stress are known to be complex, with their regulation involving multiple genes. In this review, after briefly exploring some known causes of hypoxic stress in aquaculture systems, we discuss the physiological adaptation strategies used by crustaceans in response to hypoxia and summarise recent information regarding the effects of hypoxia on the behaviour, survival, antioxidant ability, metabolic processes and innate immunity of crustaceans. In addition, we give particular emphasis to the known molecular mechanisms underlying hypoxia related to the hypoxia‐inducible factor 1 (HIF‐1) signalling pathway, the adenosine 5′‐monophosphate‐activated protein kinase signalling (AMPK) pathway, and apoptosis. Practically, it is clear that multiple measures need to be taken to prevent and regulate the adverse effects of hypoxic stress in intensive aquaculture systems, including development of hypoxia‐resistant breeds and nutritional regulation techniques. Overall, this review provides a theoretical basis for understanding the molecular mechanisms underlying hypoxic stress in crustaceans, while making conceptual connections with data from related study areas in other species.
