摘要

本研究首次考察了三种不同的培养方法(底托盘培养、悬浮托盘培养和海滩/底培养)在从种子到商业规模的12个月生长培养后对嘴獭蛤(Lutraria philippinarum)生长和存活率的影响。分析包括体重、存活率、壳大小和总脂肪。结果显示,不同培养方法间的生长差异有限,但三种不同培养方法间的成活率差异显著。底盘法成活率最高(76.5%),高于悬盘法(31.6%)和滩底法(52.5%)。这表明最适合商业养殖的方法是在基质底部放置培养托盘。改善该物种的商业养殖将支持越南和其他地方水产养殖的发展和扩大,同时减少野生种群的收获压力。

Effect of Different Culture Methods on Growth and Survival of the Snout Otter Clam, Lutraria philippinarum, in Bai Tu Long Bay, Vietnam
This is the first study to examine the effect of three different cultivation methods (bottom-tray culture, suspended-tray culture, and beach/bottom culture) on the growth and survival rates of the snout otter clam, Lutraria philippinarum, after 12 months of grow-out cultivation from seed to commercial size. Analyses included weight, survival, shell size, and total fat. Although the results showed limited differences in growth among cultivation methods, survival rates were significantly different among three different culture methods. The bottom-tray cultivation method had the highest survival rate (76.5%), compared with suspended-tray cultivation (31.6%) and beach/bottom cultivation (52.5%). This demonstrates that the most suitable method for commercial snout otter clam farming is cultivation trays placed on the bottom of the substrate. Improving commercial farming of the species will support the development and expansion of aquaculture in Vietnam and elsewhere, while reducing the harvest pressure on wild populations.
