“…In this context, it is notable that we observed FCRs as low as 1.4, which compares favorably to other species that are known as efficient feed converters, such as L. vannamei, and some insects (Hung and Quy, 2013;Oonincx et al, 2015). In comparison, the FCR of P. clarkii with similar sizes to the animals used in our study was found to be 2.8 with standard feed and could be improved to 1.9 by the addition of flavonoid feed supplements (Liu et al, 2020). Additional research is required to further optimize marbled crayfish feed conversion with less refined feeds and different culture conditions to fully realize their potential for the sustainable production of nutritional protein.…”

The marbled crayfish (Procambarus virginalis) is a recently discovered freshwater crayfish species, which reproduces by apomictic parthenogenesis, resulting in a monoclonal, and all-female population. The animals were widely distributed through the aquarium trade and have established numerous stable wild populations through anthropogenic releases. They are highly prevalent in Madagascar, where they have become a popular source of nutritional protein. As freshwater crayfish aquaculture in open systems is a thriving, but ecologically damaging global industry, alternatives are urgently needed. Although marbled crayfish are often branded by their invasive mode of reproduction, their overall invasiveness is not higher than for other cultured crayfish species. Furthermore, their resiliency and high adaptability provide a strong rationale for evaluating them for closed, and environmentally safe aquaculture approaches. Here we describe a novel population of marbled crayfish in a former German coal mining area that is characterized by acid and polluted water. Even under these adverse conditions, animals grew to sizes, and weights that are comparable to commercially farmed freshwater crayfish. Tailored feed development and laboratory testing demonstrated highly efficient feed conversion, suggesting a considerable capacity for sustainable production in closed systems. We further show that marbled crayfish meat can be readily introduced into European meals. Finally, chemical analysis of marbled crayfish exoskeletons revealed comparably high amounts of chitin, which is a valuable source for the synthesis of chitosan and bioplastics. Our results thus suggest that production of marbled crayfish in closed systems may represent a sustainable alternative for crayfish aquaculture.

“…In present study, dietary BT obviously declined the level of haemolymph ACP, LZM and TP; this may be associated with the deficiency of n ‐3 HUFA (Figure 3). Contents of TP, ACP, AKP and LZM in haemolymph are often regarded as the relevant indicators to evaluate immune regulation of crustaceans (F. Liu, Qu, et al, 2020; Ray et al, 2020). And the decrease in these parameters implies a depressed immune modulation and disease resistance (F. Liu, Qu, et al, 2020; Pang et al, 2019; Qin et al, 2012; Yuan et al, 2019).…”

Beef tallow (BT) has attracted research interests of fish oil (FO) sparing in aquafeed, but total replacement of dietary FO by BT might damage aquatic animal health as a controversial issue for years. This study aimed to investigate the effects of BT partially or completely replacing FO on the health of red swamp crayfish (Procambarus clarkii), especially antioxidant capacity and immune response. Three experimental diets containing FO, BT and a blend of FO and BT (FB, 1:1) as lipid sources, respectively, were formulated to feed crayfish for 8 weeks. The results showed crayfish exhibited no significant differences (p > 0.05) in growth and body proximate composition regardless of dietary lipids. Crayfish fed a BT diet were observed higher contents of haemolymph triglyceride and free fatty acid (FFA) compared with crayfish fed FO (p < 0.05), while FB diet tended to reverse this effect. For hepatopancreas antioxidants, crayfish in the FB group showed higher levels of catalase and glutathione and lower malondialdehyde content than those in the FO group (p < 0.05). Furthermore, BT diet feeding decreased the contents of haemolymph acid phosphatase, lysozyme and total protein compared with FO diet, but FB diet tended to improve these immunological parameters. FB inclusion reversed the BT‐induced suppression of nuclear factor kappa beta mRNA expression and enhancement of mitochondrial manganese mRNA expression versus BT, implying ameliorative immunity function. Taken together, total replacement of dietary FO by BT might be detrimental to the health of crayfish, while partial substitution of dietary FO with BT neither suppresses growth nor impairs antioxidant capacity and innate immunity of crayfish.

Background Danggui Buxue Tang (DBT), an ancient Chinese herbal decoction containing Astragali Radix and Angelicae Sinensis Radix at a ratio of 5: 1, is prescribed for menopausal women. Flavonoids and its flavonoid glycosides are considered as the major active ingredients within the herbal decoction; however, their amount is not controllable during the preparation. Besides, the aglycons within DBT are believed to have better gut absorption and pharmacological efficacy. Methods The herbal extract of DBT was fermented with Lactobacillus plantarum. The amounts of flavonoid glucosides and its aglycones in the fermented product were analyzed by using UPLC-MS/MS. In addition, in vitro assays were employed to evaluate the efficacy of the fermented DBT in regulating the activities of α-glucosidase, α-amylase and lipase, as well as their antioxidant capacity (DPPH and T-AOC assays) and anti-glycation property (BSA-methylglyoxal, BSA-fructose, and arginine-methylglyoxal models). Results The fermentation of DBT with L. plantarum drove a completed conversion of calycosin-7-O-β-D-glucoside and ononin to calycosin and formononetin, respectively. The chemical transformation could be probably mediated by β-glycosidase within the fermented product. Several in vitro assays corresponding to anti-diabetic functions were compared between parental DBT against its fermented product, which included the activities against α-glucosidase, α-amylase and lipase, as well as anti-oxidation and anti-glycation. The fermented DBT showed increased activities in inhibiting α-glycosidase, suppressing DPPH radical-scavenging and anti-glycation, as compared to the original herbal product. Conclusion These results suggested that DBT being fermented with the probiotic L. plantarum could pave a new direction for fermentation of herbal extract, as to strengthen its pharmacological properties in providing health benefits.
