摘要/Abstract

摘要： 为改进菲律宾蛤仔苗种中间培育技术，对福建省晋江市围头湾浅海中培的菲律宾蛤仔稚贝生长和海区环境进行了调查分析。结果显示，从2019年1月到4月，海区水温逐渐上升，盐度逐渐下降，但均处于菲律宾蛤仔稚贝适宜范围；浮游植物以硅藻为主，1月份密度为5 100个/L，4月份密度为8 300个/L；菲律宾蛤仔稚贝壳长由（2.33±0.75）mm生长至（11.14±2.52）mm，成活率为30.30%。

Abstract: In order to improve the nursery culture technique of Ruditapes philippinarum, a survey for the juvenile growth and environmental parameters was carried out at Weitou Bay of Jinjiang, Fujian Province, China. From January to April, 2019, the water temperature increased while the salinity gradually decreased, both were within the suitable range. Diatoms dominated the phytoplankton, with a density of 5 100 cells/L in January and 8 300 cells/L in April. The shell length of juveniles increased from (2.33±0.75) to (11.14±2.52) mm, but the survival rate was 30.30%. Comprehensive analysis showed that the high death rate might be caused by predators.
