摘要
采用四种开口饵料对大马哈鱼仔鱼进行了30 d驯化试验。结果表明,枝角类开口饵料成活率最高,达91.5%,其次是水丝蚓组,达90%、鱼糜组,达83%、配合饲料组,达62%;水丝蚓组的全长生长率最高,达61.9%,其次是鱼糜组,达41.8%,配合饲料组,达40.5%,枝角类组,达21.4%。
A domestication experiment feeding larvae oncorhynchus keta with four kinds of larval - stage feed for 30 days was conducted. It was found that the survival rate and full - length growth rate were different. The sur- vival rate of the larvae fed with Moina sp. was the highest （ 91.5 % ）, followed by that fed with Limnodrilus sp. （90%）, surimi（83% ） and formulatedfeed（62% ）. The full - length of the larvae fed by Limnodrilus sp. was the highest（61.9% ）, followed by that fed by surimi （41.8%） ,formulated feed（40.5% ）and Moina sp. （21.4%）.
