摘　　要：该研究通过南移养殖的方法,测定了富齿岩虫(Marphysa maxidenticulata)在广西北海地区的生长状况,并比较了南北方虫体营养成分。结果显示,经240 d的养殖,虫体平均体长达(12.66±1.52)cm,平均体质量达(2.30±0.86)g。试验前期,海泥底质组虫体的特定生长率显著高于粗砂底质组;而粗砂底质组的虫体在养殖后期表现出较高的特定生长率。营养组成分析结果显示,广西北海养殖和山东乳山野生虫体均含有18种氨基酸,但其基本营养组成存在显著差异(P<0.05)。北海养殖虫体氨基酸总量(TAA)、呈味氨基酸(DAA)、非必需氨基酸(NEAA)、半必需氨基酸(SEAA)、必需氨基酸(EAA)含量均高于乳山野生虫体。在脂肪酸组成方面,2个地区的富齿岩虫均含有27种脂肪酸,且以棕榈酸和油酸为主要脂肪酸;乳山野生虫体饱和脂肪酸含量和多不饱和脂肪酸含量与广西北海养殖虫体无显著差异;北海养殖虫体单不饱和脂肪酸总含量显著高于乳山野生虫体(P<0.05)。In this paper,we investigated the growth condition and nutritional composition of Marphysa maxidenticulata cultured in Beihai by using the"northern worm and southern cultivation"method.The results show that the average body length of M.maxidenticulata grew up to(12.66±1.52)cm and the average body mass was(2.30±0.86)g within 240 d.The specific growth rate of M.maxidenticulata in mud sediments was significantly higher than that of the coarse sands at the early phase of culture,but the late phase of culture was just opposite.The results of nutrition composition analysis show that the nutritional composition contained 18 species amino acids in both cultured M.maxidenticulata in Beihai and wild M.maxidenticulata in Rushan,but their contents were significantly different(P<0.05).The contents of total amino acid,delicious amino acid,non-essential amino acid,semi-essential amino acid and essential amino-acid of cultured M.maxidenticulata in Beihai were higher than those of wild M.maxidenticulata in Rushan.In terms of fatty acid composition,27 fatty acids had been determined in both cultured and wild M.maxidenticulata,and palmitic acid and oleic acid were the main fatty acids.There was no significant difference in the contents of saturated fatty acids and polyunsaturated fatty acids between cultured M.maxidenticulata in Beihai and wild M.maxidenticulata in Rushan.But the content of total monounsaturated fatty acids of cultured M.maxidenticulata in Beihai was significantly higher than that of wild M.maxidenticulata in Rushan(P<0.05).
