Astaxanthin as an important pigment source and antioxidant is considered that it is necessary to be provided in the diets for cultured shrimp.But the optimum supplemental amount to diets for larval and post-larval kuruma shrimp is still unrevealed.Two individual trials were conducted to evaluate the effect of chemically synthesized astaxanthin (Carophyll PinkR) on the growth performance,survival and stress resistance,respectively.Firstly,the 8-day feeding trial was conducted to investigate the effectiveness of dietary supplementation of astaxanthin on survival,growth,developmental stage (DS),metamorphosis to post-larval (PL) and formalin stress resistance (LT50) on larval kuruma shrimp.Six dietary levels of Ax (0,50,100,200,400 and 800 ppm) were added to the micro-bound diet (MBD) and fed to triplicate groups from zoea1 stage larvae to postlarvae1 stage.There were no significant differences showed on the data of survival among all the groups.
