    摘要:

    利用平均壳长为24.0 mm、平均个体重为2.0 g的西施舌人工稚贝进行水泥池中间培育试验。结果显示:采用150%的日流水量并结合底质定期冲洗和更换等措施,经177 d培育,西施舌苗种平均壳长为40.0mm,平均个体重为9.8g,基本达到养成所需的规格标准。其壳长生长速度为0.09 mm/d,体重生长速度为0.04g/d。成活率为68%,高于潮间带围网培育和土池中间培育。

    Abstract:

    Artificial breeding juveniles of Mactra antiquata with an average shell length of 24.0 mm and individual weight of 2.0 g were reared in cement tanks. Adopting the measures of 150% water replacement per day and tank sediment flushing and replacement at regular intervals, after 177 days rearing, the shellfish grew to an average length of 40.0 nun and average weight of 9.8 g, meeting the requirement of post juvenile aquaculture. The mean shell length growth rate was 0.09 mm/d, and weight growth rate was 0.04 g/d. The survival rate was 68 % , higher than that of traditional rearing in sand pool or in net cage in intertidal zone.
