Effects of Microencapsulated Diet on the Growth Performance of Crossbred Juvenile Abalone
-
摘要: 结合业者鲍苗繁育生产,用市售粉态鲍苗配合饲料作对照,进行为期129d的稚幼鲍微胶囊饲料对杂交鲍苗生长性能的影响试验。试验至92d,试验Ⅰ组(微囊饲料占日给饲量的1/3)和试验Ⅱ组(微囊饲料占日给饲量的1/9)鲍苗的壳长都显著大于投喂粉态料的对照组(P<0.05);至129d,试验Ⅰ组的鲍苗壳长及鲍苗特定生长率(SGR)都显著大于对照组和试验Ⅱ组(P<0.05),而试验Ⅱ组与对照组差异不显著(P>0.05)。试验Ⅰ组的鲍苗成活率比试验Ⅱ组和对照组高出2个百分点,但差异不显著(P>0.05)。试验结果显示:用稚幼鲍微胶囊饲料取代市售的粉态料给饲量的1/3~1/9饲喂的鲍池形成了杂交鲍苗不同程度的生长优势。Abstract: According to current situation of larval abalone breeding production,an 129-days experiment was conducted to test the effects of microencapsulated diet on the growth of crossbred juvenile abalone.The commercially available powder state abalone formulated diet was used as a control.At the 92th day,the abalone shell length of groupⅠand groupⅡ were significantly higher than those of the control fed with powder state diet(P<0.05);and at the last day,the abalone shell length and the specific growth rate(SGR) of the abalone shell length of groupⅠwere significantly higher than those of the control and groupⅡ,while no significant difference was found between the control and groupⅡ.The survival rate of the juvenile abalone in groupⅠwas two percents higher than others,but the difference was not significant(P> 0.05).The results indicated that the crossbred juvenile abalone fed with microcapsules diet which accounted for 1/3 or 1/9 ration showed various degree of dominant growth.
