Haematococcus pluvialis  can be used as a green additive in aquafeeds due to it contains rich astaxanthin and polyunsaturated fatty acid. In the present study, a newly strain of  H. pluvialis  GXU-A23 with high concentration of astaxanthin was firstly isolated by a newly culture strategy in our laboratory. In addition,  H. pluvialis  GXU-A23 was applied in the  Litopenaeus vannamei  feed for determining whether it has positive effects on the growth performance, antioxidant and anti-inflammatory status, metabolic capacity and mid-intestine morphology of juvenile  L. vannamei . Shrimp with 0.63 g approximately initial body weight were fed diets supplemented with/without 50 g/kg  H. pluvialis  GXU-A23. After 8 weeks feeding intervention, significantly higher growth performance of  L. vannamei  was obtained in the  H. pluvialis  GXU-A23 treatment group compared to the control group ( p  &amp;lt; 0.05). At the same time,  L. vannamei  fed with  H. pluvialis  GXU-A23 acquired significantly better antioxidant and anti-inflammatory status than the control group ( p  &amp;lt; 0.05). In addition, higher RNA expression level of hepatopancreas digestive enzyme, hepatopancreas lipid and glucose metabolic enzymes as well as better mid-intestine morphology were found in the  H. pluvialis  GXU-A23 treatment group than the control group ( p  &amp;lt; 0.05). These results indicated that 50 g/kg  H. pluvialis  GXU-A23 was suitable for the  L. vannamei  feed, which could improve the growth performance, antioxidant and anti-inflammatory status, metabolic capacity and mid-intestine morphology of juvenile  L. vannamei.
