摘　　要：2010年6月24日至10月8日,以采自金沙江的34尾圆口铜鱼(Coreius guichenoti)仔鱼(出膜3～4d)为驯养试验对象,仔鱼阶段分别以蛋黄和水蚯蚓碎浆作开口饵料,稚鱼、幼鱼阶段投喂人工配合饲料,圆口铜鱼仔鱼、稚鱼、幼鱼均能主动摄食。经107d驯化培育,总体成活率64.71%,幼鱼平均体长(70.5±4.6)mm,平均体重(5.9±1.3)g,表明圆口铜鱼仔幼鱼易于驯养。34 larvae （ after hatching 3 - 4 days） of largemouth bronze gudgeon （ Coreius guichenoti） collected from the Jinsha River were tested. The larvae of C. guichenoti cultured in 2 aquariums equally, fed with the egg yolk and mashed Mierodrili as first feed separately in 7 days. Then the larvae and juveniles of C. guichenoti were fed with compound feed, and the fries, larvae and juveniles of C. guichenoti could perform active ingestion. After the domestication of 107 days, the total survival rate was 64.71%, with average body length （70.5 ±4.6） mm, and body weight （5.9 ± 1.3 ） g. The result indicated that larval and juvenile C. guiehenoti was easy to domesticate.
