AbstractGastric mills of 362 specimens of two-year-old Chinese mitten crab (Eriocheir sinensis), which contained recognizable food items, from Lake Bao'an, China were examined. The food items were macrophytes, algae, arthropods, oligochaetes, fish, protozoa, rotifers, gastropods, and detritus, and the percent frequencies of occurrence (FO) for these items were 87.3%, 82.0%, 48.2%, 28.2%, 28.7%, 0.3%, 0.6%, 0.3% and 88.7%, respectively. Unidentified animal tissue was often observed and had a FO of 46.1%. In total, FO of plants (macrophytes + algae) was 87.7% and of animals was 89.8%. However, 5.8% of the gastric mills contained only animals, 5.3% had only macrophytes, and 0.3% contained only algae. There was no significant difference (p>0.05) in food habits between male and female crabs. The ratio of cell number of macrophytes to algae was about 156:1.
