| 摘要: |
| 对海南黎安港的企鹅珍珠贝养殖群体的生长进行了20 个月的观察, 每月测量其壳高(SH)、最大对角线长(MDL)、绞合线长(HL)和总重(TW)四个生长指标, 并用模型y = y∞ / ( 1+e?k(t?a)+d(t?b)sin(2π/365.25))分别拟合这四个指标的生长曲线。结果表明, 三个长度指标中MDL 生长速度最快, 其理论最大值约为112mm; HL 的生长在初期快于SH, 但到养殖实验结束时两者接近, 理论最大值都在85mm 左右;总重的增长在实验的前半段非常缓慢, 但到后半段呈加速增长趋势, 其理论最大值约为115g。企鹅珍珠贝的生长特征表现为初期长度增长迅速, 经过大约一年左右, 长度的增长减缓, 而重量的增长开始加快, 符合双壳贝一般的增长模式。研究也表明, 在海南黎安港, 降雨季节与快速生长季节存在明显的对应关系, 暗示了降雨可能是导致生长出现季节性特征的诱因。

| Abstract: |
| Growth of cultured winged pearl oyster, Pteria penguin was studied in 20 months in Li’an Lagoon, Hainan, south China. The growth parameters of maximum diagonal length (MDL), shell length (SH), hinge length (HL) and total weight (TW) were measured monthly and described using y = y∞ / ( 1+e?k(t?a)+d(t?b)sin(2π/365.25)). The results reveal that among the three length parameters, MDL had the largest growth, with the theoretical maximum (y∞) of 112mm; the increase of HL was faster than that of SH at the beginning, but the difference disappeared in the end and the two had almost the same y∞ at approximately 85mm; the growth of TW remained almost stagnant in the first half of experiment period, but speed up in the second half, with y∞ at 115g. The growth of P. penguin was characterized by fast initial increment of shell size, subsequent to which the total weight increased. It was revealed that the fast growth season of oysters corresponded with the rain season in the study area, which implies that the rainfall probably led to the seasonal variation in growth.
