摘　　要：1998年6月至2000年7月对浙江省乐清湾塘养泥蚶的生长进行了详细的观察。刚孵化变态的D形幼虫壳长92～100μm,经10d培育达到180.5～201.5μm,平均每日增长8.9～10.2μm;稚贝附着后16d平均壳长从191.3μm增长到634.1μm,平均每日增长27.7μm;出库稚贝放养于围塘内,培育9个月平均壳长达到8.34mm,成为商品贝苗,平均每月增长0.86mm,其中9-10月份增长可达1.65mm;再经15个月培育达到成品贝,平均壳长28.57mm,平均每月增长1.35mm。泥蚶是一种慢生型贝类。对室内浮游幼虫、稚贝、中间暂养贝苗、成蚶养殖期间的多项生长指标进行测量和称重,获得的相关关系非常显著。From January 1998 to July 2000, detailed observation were made on the growth of blood clam, Tegillarca granosa, in the pond culture of Leqing Bay (Zhejiang Province, China). Larva ( just hatched) is 92-100μm in shell length, after 10 days cultivation, it attains 180.5-201.5μm in shell length,average increase of 8.9-10.2μm per day. After attachment, juveniles increase to 634.1μm in shell length from 191.3μm, average increase of 27.7μm per day. Juveniles at mid culture in pond, average shell length achieves 8.34mm in 9 months, this is the commodity seeding, average increase 0.86mm per month. After 15 month rearing, it becomes the finished product, average shell length 28.57mm,average increase 1.35mm per month. Tegillarca granosa belongs to slow growth type. Several growth indexes of the blood clam larvae and seeding in cultural ponds, juveniles at mid culture, and mature blood clam were measured and weighed. The following regression equations, which have closely correlation were obtained:(1) Linear regression equation of shell height(H) and length(L) of blood clam larvae: L=58.547+0.859H(2) Linear regression equation of shell height(H) and length(L) of blood clam seeding: L=128.643+1.795H(3) Linear regression equation of shell height(H) and length(L) of blood clam juveniles:L=1.517H-0.368(4) Linear regression equation of shell height(H) and length(L) of mature blood clam: L=1.660H-9.563(5) Linear regression equation of shell width (D) and length(L) of mature blood clam: L=1.349+1.425D(6) Functional equation of body weight (W) and length (L)of mature blood clam:W=0.831L3.425
