Crabs, particularly the Chinese mitten crab (Eriocheir sinensis), are not only a culinary delicacy but also offer numerous health benefits. Recent studies have explored various dietary supplements and their effects on the growth, immunity, and overall health of crabs, providing insights into the potential health benefits of consuming crabs.

Growth Performance

Several studies have demonstrated that dietary supplements can significantly enhance the growth performance of crabs. For instance, mannan oligosaccharide (MOS) supplementation at optimal levels improved weight gain and specific growth rates in juvenile Chinese mitten crabs1. Similarly, icariin (ICA) supplementation was found to increase weight gain and survival rates, indicating improved growth performance2. Garlic powder also promoted growth by enhancing the final body weight and specific growth rate of crabs3.

Antioxidant Capacity

Crabs possess a natural antioxidant capacity that can be further enhanced through dietary interventions. MOS supplementation increased antioxidant capacity by up-regulating genes related to immunity and antioxidant activities1. Icariin and garlic powder supplementation also boosted antioxidant enzyme activities, such as superoxide dismutase and glutathione peroxidase, which are crucial for combating oxidative stress2 3. Sodium butyrate was shown to mitigate oxidative stress and improve antioxidant enzyme activities in crabs5.

Immune System Enhancement

The immune system of crabs can be significantly strengthened through dietary supplements. MOS, icariin, and garlic powder have been shown to enhance non-specific immunity by increasing the activities of immune-related enzymes and up-regulating immune gene expression1 2 3. Additionally, bio-fermented selenium supplementation improved immune performance by enhancing the activities of immune enzymes and increasing the expression of antimicrobial peptides7.

Intestinal Health

Dietary supplements can also improve the intestinal health of crabs. Garlic powder and sodium butyrate were found to enhance the intestinal flora structure and integrity, respectively, promoting a healthier gut environment3 5. Yeast extract supplementation improved the edible viscera index and crude protein content, indicating better intestinal health and nutrient absorption10.

Conclusion

The consumption of crabs, particularly when they are fed with specific dietary supplements, can offer numerous health benefits, including improved growth performance, enhanced antioxidant capacity, strengthened immune system, and better intestinal health. These findings highlight the potential of crabs as a nutritious food source that can contribute to overall health and well-being.
