In the present study the effects of dietary <em>Chlorella</em> on the immune status of gibel carp, <em>Carassius auratus gibelio</em>, were evaluated. A total of 540 healthy fish were divided into 6 groups, with one control group fed with <em>Chlorella</em>-free diet and five experimental groups fed diets supplemented with 0.4 to 2.0% <em>Chlorella</em>. The whole trial lasted 60 days. At the end of the trial, the weight gain and immune parameters of fish were analysed. Results showed that <em>Chlorella</em> could increase the levels of immunoglobulin M and D, interleukin-22 and chemokine (C-C motif) ligand 5 in some tissues, which indicated that dietary <em>Chlorella</em> can be involved in regulating adaptive and innate immunity.
