摘　　要：为了了解大黄鱼(Larimichthyscrocea)野生群体和养殖群体脊椎骨骨骼显微结构的差异,本研究运用了MicroCT技术对大黄鱼全鱼骨骼系统进行了扫描与三维重建,选取野生群体和养殖群体背部和尾部脊椎骨进行了显微结构参数差异分析。结果显示,大黄鱼脊椎骨与头骨、尾骨相连,脊椎骨26个,肋骨附着在第1~11腹椎,无肌间刺,胸鳍位于头骨后,背鳍、腹鳍、臀鳍和尾鳍与脊椎骨并不相连。大黄鱼野生群体背部和尾部脊椎骨的组织矿物质密度和骨矿物质密度均显著高于养殖群体(P<0.01),骨体积分数较养殖群体大(P<0.05),骨小梁间隔较养殖群体小(P<0.05),骨小梁数量、骨小梁厚度和结构模型指数上没有差别。推测是由于野生群体和养殖群体食物组成、生活环境以及活动情况等差异造成的。To understand the differences in the spine microstructures of cultured and wild stocks of Larimichthy scrocea, we used the micro CT scanning technique to capture the full fish of L. crocea. Then, we compared the bone structure parameters of the dorsal and caudal vertebra in the cultured and wild stocks. The results show the head andtail to be directly connected with the trunk and 26 vertebrae, ribs were attached to the 1–11th abdominal vertebrae,and the inter-muscular bones, pectoral fin, dorsal fin, ventral fin, anal fin, and caudal fin were not separated from the vertebrae. Bone mineral density, tissue mineral density, and bone volume fraction of the wild stock were all higher than those of the cultured stock, the trabecular spacing of the wild stock was lower than that of the cultured stock, and there was no difference in the wild and cultured stocks in their trabecular number, trabecular spacing, or structure model index. We attribute these differences to different nutritional, environmental, and movement elements of wild and cultured stocks.
