Clams from the Fujian group, the Laizhou group, and the zebra strain group were used in this investigation; their shell lengths were 1.0 cm, 1.5 cm, and 2.0 cm, respectively. Tests were conducted on substrates with particle sizes ranging from 151 to 180 µm, 181 to 250 µm, 251 to 425 µm, and 426 to 850 µm. Both centralized and decentralized sowing modes were used. According to the findings, the clams with the 1.0 cm shell length had the highest burrowing rate and the lowest ET. From 0 to 120 min, the burrowing rate of the zebra strain group was higher than that of the other groups. Clams with shell lengths of 1.0 cm and 1.5 cm had similar burrowing rates at the end of the test, with the zebra strain group having the highest burrowing rate. Manila clams burrowed more quickly when the substrate's particle sizes were between 181 and 425 µm. The clam burrowing rates in the decentralized sowing mode were high during the first 20 min of the test, but at the end of the test, there was no significant difference between the two sowing modes ( > 0.05). In summary, there were differences in the burrowing ability among the three groups. The clams with a shell length of 1.0 cm in the three groups had a higher burrowing efficiency, and the decentralized sowing mode was more conducive to the clams quickly burrowing into the substrate.
本研究使用了福建群体、莱州群体和斑马品系群体的蛤；它们的壳长分别为1.0厘米、1.5厘米和2.0厘米。在粒径范围为151至180微米、181至250微米、251至425微米和426至850微米的基质上进行了试验。采用了集中播种和分散播种两种方式。结果表明，壳长1.0厘米的蛤的潜泥率最高，而ET最低。在0至120分钟内，斑马品系群体的潜泥率高于其他群体。试验结束时，壳长1.0厘米和1.5厘米的蛤的潜泥率相似，其中斑马品系群体的潜泥率最高。当基质粒径在181至425微米之间时，菲律宾蛤仔潜泥更快。在试验的前20分钟内，分散播种模式下蛤的潜泥率较高，但在试验结束时，两种播种模式之间没有显著差异（P>0.05）。综上所述，三组之间的潜泥能力存在差异。三组中壳长1.0厘米的蛤具有较高的潜泥效率，且分散播种模式更有利于蛤快速潜入基质中。
