摘要/Abstract

摘要： 2012年10月在长乐沿海布设31个站位开展西施舌资源调查，仅在4个站位采集到西施舌，占全部站位的12.9%。调查共采集西施舌9个，总重量376.5 g；样品壳长27.11～113.55 mm，平均61.29 mm；个体重2.0～162.0 g，平均41.8 g。栖息密度和生物量最高值分别为144.30个/hm2和4.98 kg/hm2。调查结果表明长乐沿海西施舌资源已经明显衰退。

Abstract: The resource of Coelomactra antiquata was investigated in Changle coastal waters in October 2012. 9 samples were collected at only 4 investigation sites, accounting for 12.9% of the all sites. The shell length of the samples is 27.11mm～113.55mm, average of 61.29mm; the body weight is 2.0g～162.0g, average of 41.8g. The maximum value of distribution density and biomass of Coelomactra antiquata was 144.30 ind./hm2 and 4.98kg/hm2 respectively. The results show that the resource of Coelomactra antiquate in Changle coastal waters was declined obviously.
