摘　　要：在16、20、24和28℃这4个设定的水温下,以杂色鲍(Haliotis diversicolor)日本群体、台湾群体、越南群体和"东优1号"为材料,进行为期40 d的养殖试验,对4个杂色鲍群体在不同温度下的壳长日增长率(LGR)和体重日增长率(WGR)进行比较.结果表明,"东优1号"杂色鲍群体在28℃时的LGR和WGR值分别达到162.23±15.79μm/d和46.52±6.89 mg/d,在4个温度下的LGR和WGR值都优于其他3个群体,台湾群体在较高温度(24和28℃)条件下的LGR和WGR值要高于日本群体,而日本群体在较低温度(16和20℃)时的值则高于台湾群体.双因素方差分析的结果进一步表明,温度对杂色鲍不同群体的生长率指标具有显著影响.The small abalone, Haliotis diversicolor, is naturally distributed along the coastal waters of East Asia and is a commercially important species cultured along the coast of southern China. The current study genetically char- acterized four different small abalone populations （Japan, Taiwan, Vietnam, and ＂Dong You No. 1 ＂） that were reared at 16, 20, 24, and 28℃ for 40 days, and the values of length growth rate （LGR） and weight growth rate（WGR） were investigated. The study revealed that the Dong You No. 1 and the Vietnam populations had the high- est and lowest values of LGR and WGR, respectively. Dong You No. 1 reached 162.23±15.79 Ixm/d for LGR and 46. 52 ±6.89 mg/d for WGR at 28℃. In terms of LGR and WGR, the Taiwan population performed better than the Japan population at higher temperatures （24 and 28℃ ）, while the Japan population performed better than the Tai- wan population at lower temperatures （ 16 and 20℃ ）. The impact of population and temperature on LGR and WGR was investigated by two-way analysis of variance. The current study indicated that the impact of population and tem- perature on growth were both highly significant （p 〈0. O1 ）, and a significant association （p 〈0.05 ） between pop- ulation and temperature was also found. The results provide useful information for optimal growth conditions for the small abalone industry.
