“…Figure shows that AST DHA diester (Asta‐C22:6/C22:6) and Asta‐C22:6 decreased by 20.13% and 35.15% respectively during 7 days of iced storage and decreased by 6.50% and 7.96% respectively after 4 weeks of frozen storage. This result indicates that AST‐Ds in L. vannamei are more stable than AST‐Ms during storage, which is probably due to lower molecular polarity of AST‐Ds than AST‐Ms, a property that is conducive to maintaining facilitate the tight attachment of astaxanthin to biological tissues.. Fanning et al . determined the color and AST content during long‐term frozen storage and highlighted color changes, along with AST degradation patterns.…”

BACKGROUND: In this paper, the changes in free astaxanthin (F-AST) and astaxanthin esters (AST-Es) in Litopenaeus vannamei during iced storage and frozen storage were investigated. The liquid chromatography-atmospheric pressure chemical ionization tandem mass spectrometry method was used to quantify the molecular species of AST-Es in shrimp during storage. RESULTS:Based on the analysis of autoxidation products, apo-12-astaxanthinal and apo-13-astaxanthinone docosahexaenoic acid (DHA) ester were identified as the major oxidation products of F-AST and AST-Es in L. vannamei during storage. The total astaxanthin (T-AST) content decreased by 34.51% after 7 days in iced storage. In contrast, the content of T-AST decreased by 43.76% after 12 weeks in frozen storage. The content of F-AST decreased by 29.99% while 13-cis-astaxanthin increased after 3 days in iced storage, which indicated that degradation of AST was accompanied by isomerization. Total volatile basic nitrogen and T-AST content showed a significant negative correlation while in frozen storage, where the concentration of T-AST might be one indicator to evaluate shrimp freshness. CONCLUSION: The correlation coefficients between phenol oxidase, lipoxygenase, apo-12-astaxanthinal, and apo-13-astaxanthinone DHA ester were all greater than 0.97 (P < 0.01). This correlation indicates that phenol oxidase and lipoxygenase were the main internal factors to improve oxygenation of astaxanthin in L. vannamei. These results provide a theoretical basis for further study of oxidation and the degradation mechanism in astaxanthin, as well as a new idea for the development and utilization of astaxanthin compounds in Pacific white shrimp.

“…Crustaceans have the capacity to store a great quantity of carotenoids or convert these carotenoids into Axn before depositing in the tissues [68,69]. In crustaceans, the content of deposited Axn correlates well with tissue redness, with many studies reporting redness values as an intuitive predictor of tissue Axn concentrations [10,70]. As expected, Axn concentration in the ovaries and hepatopancreas increased synchronously with tissue redness (a * ) in the present study.…”

Astaxanthin (Axn) is an essential carotenoid for crustacean pigmentation, and docosahexaenoic acid (DHA) is an important fatty acid; both play key roles in maintaining the health of many aquaculture species. The present study explored the combined effect of dietary Axn and DHA on gonadal development and carotenoid deposition in adult females of the Chinese mitten crab, Eriocheir sinensis. A 2 × 3 factorial design of experimental diets was created to contain two levels of Axn (0 mg/kg and 100 mg/kg) and three levels of DHA oil (0%, 0.33%, and 0.67%). The results showed as follows: (1) For the culture performance, dietary DHA oil significantly increased the gonadosomatic index (GSI), and Diet 2 (Axn 0% + DHA oil 0.33%) had the highest GSI among all treatments. (2) For the enzymatic indicators in the hepatopancreas and hemolymph, supplementation with 0.33% DHA oil significantly improved the antioxidant capacity (T-AOC and MDA), immunity (AKP and ACP), and health status (e.g., GPT and GOT) of E. sinensis. (3) Supplementation with 100 mg/kg Axn significantly increased redness (a ∗ ) and Axn concentration in both the ovaries and hepatopancreas, and supplementation with 0.33% or 0.67% DHA oil produced a further significant improvement in Axn concentration when the diets were supplemented with 100 mg/kg of Axn. (4) As for proximate composition, dietary Axn and DHA significantly increased the deposition of total lipids and triacylglycerol in the hepatopancreas. As expected, the crabs fed diets with DHA supplementation showed an increase in the DHA percentage and DHA/EPA ratio in the ovaries and hepatopancreas. In conclusion, dietary Axn and DHA oil had positive effects on ovarian development in E. sinensis females. The optimal combination of dietary Axn and DHA oil was determined to be approximately 100 mg/kg and 0.33%, respectively, for this species during ovarian maturation.

“…In the present study, we recorded concomitant increases in values obtained for the redness ( a *) of crab carapace and ovaries and their respective carotenoid concentrations during wintering. Numerous studies have similarly reported that tissue astaxanthin contents in crustaceans are strongly correlated with redness, and thus a * values represent a good predictor of tissue astaxanthin concentrations (Fanning et al, 2016). In contrast to increases in the redness of carapace and ovary samples, we detected marked reductions in hepatopancreas redness during wintering.…”

In this study, we conducted a cage‐culture trial to evaluate the gonadal development and nutritional quality of adult female Chinese mitten crabs (Eriocheir sinensis) fed a formulated diet (FD), traditional diet (TD) or trash fish (TF) during wintering. The results revealed a marked reduction in the hepatopancreatic index (HSI) during 90 days of wintering, and that crabs fed the TF diet had a significantly higher HSI and total edible yield than those fed the TD diet after wintering (p < 0.05). In terms of proximate composition, protein and lipid contents in the ovaries showed significant increases over the wintering period, whereas there was a significant reduction in hepatosomatic protein levels. Among the three overwintering treatments, the contents of ovarian proteins and hepatosomatic lipids were significantly higher in TF crabs. Although the redness (a*) of the carapace and ovaries was found to have increased significantly during wintering, there was a significant reduction in hepatosomatic redness, which was consistent with the total carotenoid contents detected in these tissues. Moreover, among the three treatments, hepatosomatic redness was significantly higher in TF treatment after the overwintering period. In addition, nutritional quality index assessments revealed that crabs in the TF and TD groups were characterized by the highest and lowest values respectively. In conclusion, we found that the nutritional quality of adult female E. sinensis undergoes a marked decline during the wintering period. However, the provision of a TF diet can contribute to protecting against a deterioration in the nutritional quality of crabs maintained over winter.
