“…In epithelia, four carotenoids of astaxanthin, lutein, zeaxanthin and β‐carotene decreased from stage A/B to stage E, and the maximum was in stage A/B. Just like human skin, epithelia protect interior cells from high‐energy sunlight photons oxidation via the pigment deposition of four carotenoids (Chen et al, 2021; González‐Peña et al, 2021; Kruk & Szymańska, 2021). Those carotenoids in epithelia can protect interior cells from sunlight protons damages, especially in stage AB when the crustaceans just caste off its old carapaces.…”

This study was designed to demonstrate the pivotal carotenoid(s) contents and its correlation with anti‐oxidative capacities in the moulting of P. trituberculatus. Experiments were carried out to investigate the cyclic fluctuations of carotenoids contents, anti‐oxidative indices activities (contents) and non‐specific immune indices activities (contents) in the hepatopancreas, haemolymphs and epithelia of juvenile P. trituberculatus during the moulting cycle. Further, a regressing analysis was made on the correlation between carotenoids contents and anti‐oxidative indices values during the moulting cycle. The results showed that the total anti‐oxidative capacity and immunity (in haemolymphs) at ecdysis decreased drastically, even though other anti‐oxidative indices activities increased, when compared to those in the intermoult duration (or premoult) respectively. The decreases in T‐AOC mean juveniles suffer excess oxidative damages at ecdysis. Both triglycerides and carotenoids were taken up in hepatopancreas during the inter‐moult, then consumed mostly in the moulting process. The carotenoids compositions analysis results not only illustrated astaxanthin was the only carotenoid species exiting ubiquitously in hepatopancreas, haemolymphs and epithelia in all moulting stages, but also showed astaxanthin was the only one detected in haemolymphs in all moulting stages. Following correlation regression results showed astaxanthin contents were positively related to total antioxidant capacity values in haemolymphs. Accordingly, astaxanthin should be an important anti‐oxidative factor in haemolymphs during the moulting. In conclusion, those results clearly suggested astaxanthin should be the ubiquitous and abundant carotenoid for anti‐oxidation in P. trituberculatus during the moulting cycle. This awareness may provide a understanding of astaxanthin physiological mechanism in P. trituberculatus.

“…Sample analyses were performed using crab's specific melatonin and cortisol ELISA kits supplied by Enzyme-linked Biotechnology (Qiaodu-Bio, Shanghai, China). Kits have been validated previsouly in S. paramamosain (Chen et al, 2021a). Detection limit was 1 pg mL −1 , and both intra-assay and inter-assay coefficients of variation for both kits were less than 15%.…”

“…Melatonin was reported to impact on a range of biological processes in crustaceans including glucose metabolism, oxidative stress, limb regeneration, and molting (Sainath and Reddy, 2010a,b;Sainath et al, 2013;Girish et al, 2015). A recent study from our laboratory showed melatonin levels in the eyestalks of S. paramamosain were significantly affected by light intensity (Chen et al, 2021a), however, light spectral effects remain unknown in the species.…”

“…Nevertheless, due to the unreliability of the hatchery phase in aquaculture settings, the mud crab industry still highly relies on wild harvested mud crab juveniles, raising concerns over the sector's sustainability. Unreliable hatchery supply is mainly attributed to the lack of optimized and standardized husbandry protocols during early development leading to high mortality, and variable growth performances (Chen et al, 2021a).…”

“…The fundamental function of MIH is to suppress ecdysteroid biosynthesis to regulate molting (Qiao et al, 2018). Molting, and subsequently growth, in crab species are also regulated by many abiotic factors including temperature (Yuan et al, 2017), salinity (Gong et al, 2015), and light intensity Chen et al, 2021a). Previous studies indicated that light fluctuations from blue to green or yellow spectra could promote growth and molting frequency of L. vannamei (Guo et al, 2011).…”

An 8 weeks trial was performed to test the effects of light spectra [full-spectrum, violet (405 nm), blue (470 nm), cyan (500 nm), green (525 nm), yellow (570 nm), and red (625 nm)] on growth performance, molting, antioxidant capacity, stress response and expression of molting, and apoptosis-related genes in Scylla paramamosain. Results showed that spectrum had a significant effect on S. paramamosain physiology. Compared to blue light, crabs exposed to violet light had a significantly lower survival rate (79.5 ± 3.6% vs. 94.9 ± 3.6%), weight gain (49.2 ± 5.4 vs. 67.6 ± 6.7), molt frequency (4.2 ± 0.2 vs. 4.5 ± 0.1), and extended intermolt intervals between instar 1 and 2 stages (C1–C2) (6.3 ± 0.3 vs. 5.0 ± 0.1 days). Expression of the molt-inhibiting hormone (mih) gene was upregulated in crabs reared under violet light. According to the regression analysis, maximum SGR would be at 449.97 nm. Crabs exposed to blue light also had lower melatonin levels than under full-spectrum and lower cortisol levels than violet and yellow groups. Regarding oxidative stress, crabs in full-spectrum had lower H2O2 and MDA contents, however, no significant difference was found in total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and catalase (CAT) in hepatopancreas from crabs under different spectra. Gene expression of hsp40, hsp70, hsp90 were down-regulated in crabs exposed to the full-spectrum light group. Regarding apoptosis-related genes, bcl-2 gene expression in crabs under cyan and the cox IV and caspase 3 in green were upregulated, suggesting cyan light may inhibit, while green light may promote apoptosis. Taken together, these results suggest that blue or cyan light would promote growth performance, while full-spectrum light could reduce stress response in S. paramamosain.
