摘要
本研究描述了在菲律宾伊洛伊洛北部海岸采集的笔贝的形态特征。共对 380 个贝壳完整的笔贝个体及其内收肌进行了仔细检查和测量。共研究了 11 个物种,即Atrina pectinata (Linnaeus, 1767)、Atrina inflata (Dillwyn, 1817)、Atrina vexillum (Born, 1778)、Atrina seminuda (Lamarck, 1819)、Atrina rigida ([Lightfoot], 1786)、Pinna bicolor Gmelin, 1791, Pinna atropurpurea Sowerby, 1825, Pinna deltodes Menke, 1843, Pinna muricata Linnaeus, 1758, Pinna incurva Gmelin, 1791, 以及 Pinna nobilis Linnaeus, 1758。根据 Pinna 属和 Atrina 属分别具有的 9 个和 8 个瓣阀特征对这些物种进行了鉴定。然后将这些特征与它们的内收肌形态相关联。方差分析显示,所调查的 Atrina 属中的三个优势种,即 Atrina pectinata、Atrina inflata 和 Atrina vexillum,在气门的 8 个特征上存在显著差异(P < 0.05)。此外,3 个具有代表性的 Pinna 物种,Pinna bicolor、Pinna atropurpurea 和 Pinna deltodes,在壳宽、壳背后缘、沟宽和背后缘至背侧珍珠质边缘方面均有显著差异(P < 0.05)。在五个优势物种中观察到的内收肌特性与不同贝壳长度特征之间的高度相关性(P < 0.05)可作为生长的预测指标,并表明内收肌尺寸的增加与上述贝壳特征尺寸的增加相关。菲律宾以前没有进行过此类研究。这项工作为其他笔贝物种的相关生物学研究以及伊洛伊洛北部乃至世界其他地区的笔贝资源管理提供了相关信息。
Identification of pen shells (Bivalvia: Ostreida: Pinnidae) collected off northern Iloilo, Philippines using their morphological characters
This study describes morphological characteristics of pen shells collected along the coast of northern Iloilo, Philippines. A total of 380 pen shell individuals with intact shells and their adductor muscles were carefully examined and measured. Eleven species were studied, namely: Atrina pectinata (Linnaeus, 1767), Atrina inflata (Dillwyn, 1817), Atrina vexillum (Born, 1778), Atrina seminuda (Lamarck, 1819), Atrina rigida ([Lightfoot], 1786), Pinna bicolor Gmelin, 1791, Pinna atropurpurea Sowerby, 1825, Pinna deltodes Menke, 1843, Pinna muricata Linnaeus, 1758, Pinna incurva Gmelin, 1791, and Pinna nobilis Linnaeus, 1758. The species were identified based on the nine characteristics of the valve for the genus Pinna and eight for the genus Atrina. These characteristics were then correlated with their adductor muscles’ morphology. Analysis of variance revealed that the three most dominant species investigated under genus Atrina, namely Atrina pectinata, Atrina inflata, and Atrina vexillum, were found to be significantly different in the eight characters of the valve (P < 0.05). Moreover, three representative Pinna species, Pinna bicolor, Pinna atropurpurea, and Pinna deltodes, were significantly (P < 0.05) different based on shell width, dorsal posterior shell margin, sulcus width, and dorsal posterior margin to dorsal nacreous margin. The observed high correlation (P < 0.05) between adductor muscle properties and different shell length characteristics for five dominant species can be used as a predictor of growth and suggests that the increase in the size of adductor muscle correlates to the increase in the size of the mentioned shell characteristics. No previous study of this kind was conducted in the Philippines. This work provides relevant information for related biological research on other pen shell species and for the management of pen shell resources in northern Iloilo and, possibly, other regions in the world.
