研究了不同水温对菲律宾蛤仔生长、摄食和抗凝血酶活性的影响，以确定菲律宾蛤仔生长的最适水温。在18、22、26、30、34、38 °C和室温（RT）水温条件下养殖菲律宾蛤仔后，测定其最终体重（FBW）、增重率（RWG）、比生长率（SGR）、饲料转化率（FC）、平均每次摄食量（AFI）、平均每次摄食率（AFIR）、观察64天存活率（SR）和抗凝血酶活性（AT）。结果表明，在26-30 °C温度范围内，菲杨的FBW、RWG、SGR、AFI、SR等生长指标均显著高于其他试验处理（P<0.05），而FC低于其他试验处理。菲律宾蛤仔的最适水温范围为26-30 °C，在34 °C时AT最大（295.52 U）（P<0.05）。
The effects of different water temperatures on the growth, feed intake and antithrombin activity of P. manillensis were studied in order to identify the optimum water temperature for growth. After P. manillensis were cultured at the water temperatures of 18, 22, 26, 30, 34, 38 °C and room temperature (RT), final body weight (FBW), weight gain rate (RWG), specific growth rate (SGR), feed conversion rate (FC), average feed intake per time (AFI), average feed intake rate per time (AFIR), survival rate (SR) and antithrombin activity (AT) were measured for 64 days. The result showed that FBW, RWG, SGR, AFI, and SR of P. manillensis presented different growth indices that were higher than other experimental treatments at 26-30 °C (P<0.05), while FC was lower than others. The optimal water temperature range for P. manillensis was 26-30 °C, and the results indicate that the maximum AT (295.52 U) occurs at 34 °C (P<0.05).
