菲律宾蛤仔足丝产量随生长而减少。这一趋势已得到充分承认，但尚未得到详细分析。此外，它仍然没有调查是否缺乏能力，以产生足丝丝在成年阶段是由萎缩的足丝腺或没有。本研究的目的是评估的足丝生产能力的蛤通过少年到成年阶段，并检查两个内源性因素（即壳的大小，体细胞条件）在确定足丝生产概率（蛤与足丝生产的人口比例）的重要性。这项研究还证实了组织学的存在下，深海腺的青少年到成年蛤。为了这些目的，现场调查，调查之间的关系足丝生产，壳的大小和身体状况的蛤收集从4个潮间带网站和组织学研究的蛤的足丝腺进行。这项研究表明，足丝生产的可能性降低，增加壳的大小和下降的躯体条件和足丝生产的缺乏是不是由于失去了足丝腺。
Byssus production ofRuditapes philippinarumclams becomes reduced with growth. This tendency is well recognized but has not been analysed in detail. Additionally, it remains uninvestigated whether the lack of competence to produce byssus threads in the adult stage is caused by atrophy of the byssal glands or not. The objective of this study was to evaluate the byssus production ability of clams through the juvenile to adult stages and to examine the importance of two endogenous factors (i.e. shell size, somatic condition) in determining the byssus production probability (proportion of clams with byssus production in a population). This study also histologically confirmed the presence of byssal glands in juvenile to adult clams. For these purposes, field surveys to investigate the relationship among byssus production, shell size and somatic condition of clams collected from four intertidal sites and a histological study for byssal glands of the clams was conducted. This study revealed that byssus production probability decreases with increasing shell size and declining somatic condition and that the lack of byssus production is not caused by the loss of the byssal glands.
