Abstract

Chinese mitten crab (Eriocheir sinensis) is an importantly economic species farmed in China and is becoming a commonly worldwide food due to its increasing export. The nutritional compositions of Chinese mitten crab of commercial size grown in pond with different genders were analyzed in this study. The results showed that total edible yield were ~40% for both male and female crabs. Meat from muscle contributed as much as 80% of the total protein, and can be considered as a low-fat and high-protein food with relative well-balanced essential amino acids, especially that from female crabs. While the edible viscera counting ~ 99% of the total fat with rich n-3 fatty acids, especially EPA and DHA, which together with the higher n-3/n-6 PUFA ratios, proved that Chinese mitten crab grown in pond is undoubtedly an n-3 PUFA-rich food for human. No significant differences were found in all parameters tested between male and female crabs though male crab has lower values of essential amino acids score than female crabs, indicating that male and female Chinese mitten crabs have equally nutritional values.

Keywords: Chinese mitten crab, nutrient, amino acids, fatty acids, crude protein, fat, pond.
