“…The color of E. sinensis is attributable to the deposition of carotenoids, especially astaxanthin [ 21 ]. In the present study, higher a * values of freeze-dried carapace were observed fattening between SW and AW compared with that of FW, illustrating higher astaxanthin and canthaxanthin contents [ 21 , 27 ]. A similar trend was also observed with higher b * values of freeze-dried carapace fattening between SW and AW, suggesting strongly zeaxanthin and β-carotene contents [ 27 ].…”

The majority of pond-reared Chinese mitten crab (Eriocheir sinensis) grow and fatten in freshwater. Previous studies illustrated that E. sinensis cultured in saline-alkaline water in outdoor environments showed a higher quality than that cultured in freshwater. However, it is still unclear whether salinity or alkalinity has an important positive effect on the quality of E. sinensis. This study aimed to investigate the gonadal development, edible yield, coloration, and nutritional and flavor quality of E. sinensis fattening in saline and alkaline water indoors. Results showed that there were no significant changes observed in gonadosomatic index (GSI) and other edible parameters among freshwater (FW), saline water (SW), and alkaline water (AW) during the 55-day fattening period (p > 0.05). Significantly higher a* and b* values of freeze-dried female carapace were observed fattening in SW and AW compared with that of FW (p < 0.05). The crude protein in gonad and male muscle, moisture in female muscle, and crude lipid in male muscle increased significantly from FW to SW and AW (p < 0.05). Better nutritional and flavor values were also detected in male hepatopancreas and muscles. In conclusion, numerous advantages of fattening in SW and AW were observed, including the improvement of carotenoid accumulation in freeze-dried carapace, DHA, EPA, total essential free amino acids (∑EFAA), total free amino acids (∑FAA), and total umami values (∑TUV) contents in male hepatopancreas and muscle.

“…In this study, the egg production per female, fecundity and reproductive effort of purple female crabs were slightly higher than those of greenblack female crabs, but no significant difference. This may be due to the accumulation of nutrients in the purple female crab was more than greenblack in the ovaries (Li, 2019). Previous studies have shown that the E. sinensis broodstock can improve reproductive performance through nutritional fortification (Wu et al., 2007).…”

“…Selection of broodstock with high quality could represent an important strategy to improve production and quality of E. sinensis (Cheng et al., 2018; Wu et al, 2010). The carapace colour of E. sinensis is normally greenblack, while a small percentage of crabs are purple, red and white (Li, 2019; Si et al., 2017). The study on different shell colour of E. sinensis was focused on the nutritional composition (Li et al., 2020) and genetic diversity (Wang, 2018), while the reproductive performance has not been studied.…”

“…The study on different shell colour of E. sinensis was focused on the nutritional composition (Li et al., 2020) and genetic diversity (Wang, 2018), while the reproductive performance has not been studied. The E. sinensis exhibits rare purple that is distinctively different from the greenblack, and the purple crab condition has been described as a high quality with more carotenoids and fatty acid content in ovaries and hepatopancreas (Li, 2019; Li et al., 2020). The unique colour and rareness of purple crabs have driven consumer preference and result in higher prices than for the same size greenblack crabs (Li et al., 2020).…”

Colour plays a critical role in reproductive performance and egg quality in the crustacean. This study was designed to compare the reproductive performance, egg quality, colour, carotenoids, proximate, and fatty acid composition of purple and greenblack Eriocheir sinensis. The results showed that the survival rate, egg production, fecundity and reproductive effort for purple females were slightly higher than greenblack females, but not significant. The egg diameter, wet weight and dry weight of individual egg were similar between purple and greenblack. There was no significant difference for lightness (L*), redness (a*), yellowness (b*), colour difference (dE*), and total carotenoids content between purple and greenblack eggs. Purple eggs had a significantly higher astaxanthin and lutein than greenblack at 1 week (p < 0.05), while lower lutein content in purple eggs at 4 weeks (p < 0.05). The eggs produced by purple female had the significant higher C20:5n3 (EPA) than that of greenblack female. In conclusion, the astaxanthin and EPA content of purple were significantly higher than those of greenblack, but the reproductive performance, eggs colour and proximate composition were similar, which suggested that purple E. sinensis may have better high‐quality egg than greenblack E. sinensis.
