Biochemical composition of the hepatopancreas from the Chinese mitten crab Eriocheir sinensis with different signs of hepatopancreatic necrosis disease (Brachyura, Varunidae)

What is it about?

Eriocheir sinensis is an important pond-reared crab in China. Recently, hepatopancreatic albinism and necrosis have become important issues that affect the development of the crab breeding industry. In this study, hepatopancreas samples collected from a crab breeding farm were classified into four color groups (I. yellow; II. yellow-white; III. white; and IV. shrunken and necrotic) based on the appearance and color of the hepatopancreas. The four different color groups were compared with respect to hepatosomatic index (HSI), hepatopancreas histology, and conventional biochemical and fatty acid compositions of the hepatopancreas. The results showed there were significant differences in HSI, histology, conventional biochemical indices and fatty acid composition of hepatopancreas among different hepatopancreas color groups. Our results are of great significance for further understanding of hepatopancreatic albinism and necrosis.
