摘要
为考察扇贝新品系"紫海墨"的生产性能,为新品系选育效果提供依据,在同一海域养殖、相同管理模式和相同养殖周期下,对新品系"紫海墨"F4与墨西哥湾扇贝(Argopecten irradians concentricus)养殖群体的壳长、壳高、壳宽、体质量、闭壳肌质量和壳质量等7个性状及各阶段成活率进行生长特征和生产性能分析。结果表明,新品系"紫海墨"F4从10月13日养殖至翌年4月28日,壳长从1~1.5 mm长至50~60 mm的成品时,累积成活率为51.32%,显著大于墨西哥湾扇贝的29.18%(P<0.01);养殖周期内,两个养殖群体同一时期的壳长、壳高、壳宽和体质量也有极显著差异(P<0.01),新品系"紫海墨"F_(4)的生长速度高于墨西哥湾扇贝;经过6.5个月的养殖,新品系"紫海墨"F_(4)的壳长、壳高、壳宽、体质量和闭壳肌质量分别比墨西哥湾扇贝提高了19.50%、19.84%、16.23%、56.30%和20.20%。
To assess the production performance of the scallop new strain"Zihaimo"and provide references for the breeding effect of the new strain,we conducted a research in the same sea area with the same management mode and breeding cycle.By comparing seven traits of scallop farming population including shell length (SL),shell height (SH),shell width (SB),body mass(BW),adductor muscle mass (AW) and shell mass (SW) and survival rate of the new strain"Zihaimo"F_(4)with the Argopecten irradians concentricus,we analyzed their growth characteristics and production performance.The results indicate that the accumulated survival rate of"Zihaimo"F_(4)was 51.32%when it was cultured from October 13th to April 28th of the next year,and the SL was from 1–1.5 mm to 50–60 mm,which was significantly greater than 29.18%of A.irradians concentricus (P<0.01).However,the SL,SH,SB and SW of the two cultivation groups in the same period had extremely significant differences(P<0.01).It is suggested that the growth rate of the new strain"Zihaimo"F_(4)was higher than that of A.irradians concentricus.Compared with A.irradians concentricus,after 6.5 months of cultivation,the SL,SH,SB,BW and AW of the new strain"Zihaimo"F_(4)increased by 19.50%,19.84%,16.23%,56.30%and 20.20%,respectively.
