摘要
报道了对虾夷马粪海胆 (Strongylocentrotusintermedius )生殖腺、壳及饵料中无机元素 (Ca ,Mg ,Fe ,Zn ,Mn ,Cu)和蛋白质含量的测定结果。结果表明 :生殖腺中常量元素镁的质量分数高于钙 ,微量元素质量分数依次为w (Zn) >w (Fe) >w (Cu) >w (Mn) ;壳中钙的质量分数约为镁的 2 0倍 ,微量元素的质量分数依此为w (Fe) >w (Zn) >w (Mn) >w (Cu)。生殖腺和壳中无机元素的质量分数与饵料中相应元素的质量分数之间无明显相关性。此外 ,发现配合饵料在促进生殖腺发育方面明显优于海带 。
The contents of elements (Ca,Mg,Fe,Zn,Mn,Cu) and protein in gonad and shell of the sea urchin \%Strongylocentrotus intermedius\% and its diets were determined.It was found that macroelement magnesium level was 1 5～3 times higher than calcium level in gonad. In shell, however, the content of calcium was about 20 times higher than that of magnesium. The concentration of trace elements in gonad was \%w\%(Zn)>\%w\%(Fe)>\%w\%(Cu)>\%w\%(Mn), and in shell \%w\%(Fe)>\%w\%(Zn)>\%w\%(Mn)>\%w\%(Cu) in proper order. There was no significant differences in the contents of element between gonad and shell of sea urchin and its diets Furthermore, for gonad development, formulated feeds were obviously better than the kelp which, in turn, was slightly better than the formulated feeds for shell growth.
