Abstract：To clarifytheeffctsof acompound Chinese herbal medicine （formulated by Houttuyniacordata Thunb.， Plantago asiatica L.，and Portulaca oleracea L. with a weight ratio of 3：1：1 ）on fish，36O juvenile triploid crucian carp （XiangyuncruciancarpNo.3）wererandomlydivided intofour groupsandfedwithbasicfeedand experimentalfeedscontaining

2% ， 4% ，and 6% of the compound Chinese herbal medicine， respectively.The fish were cultured for 85 days.Results showedthatcomparedwiththe triploid cruciancarp fedwith basic feed，the relative growth rate and specific growth rate of thefishfedwith 6% compound Chinese herbal medicinewere significantlyreduced（ P<0.05 ），while the feed coefficient wassignificantlyincreased（ P<0.05 ）. The 4% and 6% compound Chinese herbal medicine significantly reduced the crudefatcontent of theeviscerated fish （ P<0.05 ）. Compared withthe juvenile triploid crucian carp fed with basic feed，

those fed with 2% ， 4% ，and 6% compound Chinese herbal medicine showed significantly lower hepatic total triglyceride and total cholesterol contents （ P<0.05 ），along with a significantly enhanced hepatic antioxidant capacity （ P<0.05 ）. The addition of 2% ， （2号 4% and 6% compound Chinese herbal medicine in feed improved liver histology.Furthermore，the intestinal histology was improved in the 2% and 4% groups.However，a significant reduction（ P<0.05 ）in intestinal villus height was observed in the 6% （2 group.From the research findings，it can be concluded that the addition of 2% and 4% compound Chinese herbal medicine in feed can improve the growth performance of triploid crucian carp.However，the addition of 6% compound Chinese herbal medicine is detrimental to the growth and health of the fish.
