The invention discloses a compound Chinese herb medicine addictive for culturing sea cucumber seedlings, comprising the following components in parentage by weight: 10-30 percent of manyprickle acathopanax root, 20-30 percent of astragalus root, 5-15 percent of Chinese angelica, 5-15 percent of indigowoad root, 10-20 percent of liquorice, 5-15 percent of honeysuckle and 5-15 percent of indigowoadleaf. 1-5 percent of compound Chinese herb medicine addictive is used in sea cucumber feed as a feed addictive. The invention can remarkably improve the resistance of sea cucumber on disease and increase the survival rate, has no adverse influence on the palatability of the feed and small side or toxic effects as well as low possibility of generating drug resistance and cannot be remained in aquatic products. The production process has the advantages of simple flow, convenience for use, low cost and stable source of raw materials. Proved by an experiment, the compound Chinese herb medicine addictive is used in the seedling culture stage of the sea cucumber, so that the percentage of liveweight growth is improved by 15 percent, the activity of lysozyme is improved by 20-25 percent and the survival rate is improved by 30-35 percent.
