Energy value and chemical composition (CHN) of the Chinese mitten crab Eriocheir sinensis (Decapoda: Grapsidae) from the Baltic Sea

The present study was undertaken to determine the energy value and chemical composition of the Chinese mitten crab Eriocheir sinensis Milne-Edwards, 1854, which is one of a few newcomers to the Baltic Sea. The average energy value of the studied specimens of E. sinensis was 10.96±2.11 J mg−1 DW (15.30±2.42 J mg−1 AFDW). Carbon was the major constituent of E. sinensis (33.2±3.5% DW), whereas the nitrogen and hydrogen content was 6.3±0.5 and 4.7±0.5% DW, respectively. The organic C:N ratio in E. sinensis was 4.8±0.6, on average.
