Abstract

Mangrove clam Pegophysema philippiana Reeve, 1850, is common to mangroves muddy substrate in Baganga, Davao Oriental, particularly in barangay Kinablangan, Lucod, Salingcomot and Bobonao. Sampling was done on May 2-7, 2022, during high tide. Mangrove clam length-weight relationship was calculated using the exponential equation W = aLb. A total of 769 mangrove clams were collected during sampling. The biggest (4.4 ± 0.81cm) and heaviest (43.4 ± 25.3 g) clams were recorded at Bobonao, the smallest was measured at Lucod (3.7 ± 0.65 cm), and the lightest clam was found at Kinablangan (26.8 ± 16.28 g). ANOVA detected significant differences (p < 0.05) in length and weight of mangrove clams between sites. Length-weight relationship of mangrove clam exhibited a strong positive relationship between length and weight; however, different values of slopes were noted. This is very common in bivalves because they are very sensitive to environmental changes. In general, the length-weight relationship of mangrove clam in Baganga, Davao Oriental, revealed allometric growth pattern.

菲律宾达沃省Baganga不同地点红树林蛤(peophysema philippiana)的长-重关系

红树蚌peophysema philippiana Reeve, 1850年，常见于达沃东部Baganga的红树泥质基底，特别是在Kinablangan, Lucod, Salingcomot和Bobonao。采样时间为2022年5月2日至7日涨潮期间。利用指数方程W = aLb计算了红树林蛤的长重关系。采样期间共采集到769只红树林蛤。其中，博博鳌蛤最大(4.4±0.81cm)、最重(43.4±25.3 g)， Lucod蛤最小(3.7±0.65 cm)， Kinablangan蛤最轻(26.8±16.28 g)，各地点蛤长、重差异均有统计学意义(p < 0.05)。红树林蛤的长-重关系表现出较强的正相关关系;然而，注意到不同的斜率值。这在双壳类动物中很常见，因为它们对环境变化非常敏感。总体而言，达沃东部Baganga红树林蛤的长重关系呈现异速生长模式。
