| 中文摘要: |
| 利用显微技术连续观察了背瘤丽蚌(Lamprotula leai)稚蚌发育、行为、生长和壳型变化等重要生物学特征。结果表明,刚脱落的稚蚌平均壳长208.5μm,在水温23.9～32.8℃条件下,经过75 d生长发育,进入幼蚌阶段,此时幼蚌平均壳长10.12 mm。壳长(L)、壳高(H)与日龄(t)的关系分别为L=0.220 4 e0.051 2t(R2=0.993 5)和H=0.227 7 e0.041 8t(R2=0.994 2),壳高(H)与壳长(L)的关系为H=0.781 5 L0.814(R2=0.998 1)。以稚蚌行为特征变化为依据,将背瘤丽蚌稚蚌发育划分为爬行期和埋栖期,再以稚蚌壳形状变化为依据,将爬行期稚蚌发育分为稚蚌脱落期、背部平直期、壳顶突出期,反映了背瘤丽蚌稚蚌生长与发育过程的动态变化。 |

| The important biological characteristics of juvenile Lamprotula leai,such as development,behavior,growth and change of shell shape,were observed by light microscopy.The results showed that the average shell length of newly fallen juvenile was 208.5 μm.After development and growth for 75 days at 23.9-32.8℃,it became the larval mussel with the average shell length of 10.12 mm.The relationships among shell length(L),shell height(H) and age(t) were L=0.220 4 e0.051 2t(R2=0.993 5),H=0.227 7 e0.041 8t(R2=0.994 2),and H=0.781 5 L0.814(R2=0.998 1),respectively.Based on the change of behavioral features,the juvenile development of L.leai can be divided into crawling stage and burying stage.Furthermore,the crawling stage can be divided into juvenile dropping stage,straight back stage and umbo extruding stage through the change of shell shape,which shows dynamic changes during development and growth juvenile L.leai. |
