摘　　要：采用海水皱褶轮虫(Brachionus plicatilis)、淡水臂尾轮虫(Bruchionus sp.)(维持有小球藻(Chlorella sp.))、超微粒子饵料、水丝蚓(Tubifex sp.)肉糜、摇蚊幼虫(Chironomus sp.)肉糜五组不同饵料进行江鳕仔鱼开口饵料选择试验。经15 d培育,结果表明:淡水轮虫是江鳕仔鱼最佳开口饵料,生长速度最快,成活率最高(95.42%)。A 15--day rearing experiment was conduct＇ed in this study. The different initial feeds on growth in total length and survival for larval burbot were Brachionus plicatilis, Bruchionus sp. （maintain Chlorella sp. ）,ultrafine particles feed , choppers of Tubifex sp. , choppers of Chironomus sp.. The results showed that. rotifer freshwater is the best initial feed of burbot larvae, the fastest growth rate,the highest survival rate （95.42%）.
