| 为了找到适于文蛤(Meretrixmeretrix)暂养、育肥的藻类,通过实验观察了不同藻类对成熟前文蛤生长的影响。实验共分为5组,分别单独投喂4种单胞藻,包括海水小球藻(Chlorellavulgaris)(A组)、球等边金藻(Isochrysisgalbana)(B组)、青岛大扁藻(Platymonashalgolandica)(C组)和牟氏角毛藻(Chaetocerosm櫣elleri)(D组),及混合投喂海水小球藻、球等边金藻与牟氏角毛藻(E组)。结果表明,单胞藻无论是单独投喂还是混合投喂,对成熟前文蛤的壳长和体重增长没有显著影响(P>0.05),其常规生化成分如蛋白质、脂肪、总糖及各种脂肪酸含量在某些实验组之间存在显著性差异(P<0.05)。E组蛋白质含量(63.57%)最低,与其他组之间存在显著性差异;E组脂肪含量(8.17%)除低于D组(8.64%)外,高于其他3组,但与其他组间无显著性差异;E组总糖含量(7.08%)除低于C组(7.62%)外,高于其他3组,与其他组之间存在显著性差异(P<0.05)。亚油酸(C18:2)、亚麻酸(C18:3)和花生四烯酸(C20:4)均为C组最高,含量分别为2.06%、2.28%和6.50%,与其他组之间存在显著性差异。EPA以D组为最高(8.51%),DHA以B组为最高(10.33%)。 |

| The objective of this study is that the influence of different algal species on growth of pre-mature clam Meretrix meretrix,in order to find appropriate algae for temporary-keeping and fattening of M.meretrix.The test is divided into five groups,single feeding Chlorella vulgaris(Group A),Isochrysis zhanjianggensis(Group B),Chaetoceros calcitrons(Group C) and Platymonas halgolandica(Group D),respectively,and mixed feeding is E group.The results showed that the pre-mature clam M.meretrix feeding on whether unicellular alga or mixed alga,there are no prominent influence on shell length and body weight growth(P>0.05),but there are significantly different in proximate composition such as protein,lipid,sugar and fatty acids in some test groups(P<0.05).E group have been made the lowest content of protein(63.57%),there are significant difference compared to other groups;the content of lipid(8.17%) is higher than other group except D group,there are no significant difference compared to other group except D group(8.64%);the content of total sugar(7.08%) is higher than other groups except C group(7.62%),there are significantly different compared to other groups.The contents of linoleic acid(C18:2),linolenic acid(C18:3) and arachidonic acid(C20:4) in C group are 2.06%,2.28% and 6.50%,respectively.They obtain the highest level and there are significant difference compared to other groups.The contents of eicosapentaenoic acid(EPA) and docosahexenoic acid(DHA) are the highest in D group(8.51%) and B group(10.33%),respectively. |
