摘要:2015年3月至4月,笔者对常州最大的水产市场上常见的贝类及甲壳类水产品进行了调查分析。通过走访调查及采集照片,收集水产品种共19种,其中贝类共10种,隶属3纲6目6科;甲壳类9种,隶属于甲壳纲1目6科。本研究还对这19种常见水产品的学名、拉丁名、俗名、分类地位、生活习性、养殖状况及形态特征等方面进行了总结和归纳,并阐述了我国贝类、甲壳类养殖业的现状以及未来的发展趋势。68665 毕业论文关键词:市场,甲壳类,贝类,分类地位 Abstract:From March to April of 2015, the author investigated common shellfishes and crustaceans in the largest aquatic market of Changzhou. Through investigation and photo-taking, a total of 19 aquatic species were collected. Among these organisms, there were 10 shellfishes distributing in 3 classes, 6 orders and 6 families, the rest 9 species were crustaceans belonging to 1 order and 6 families of the crustacean class. In this paper, the scientific, Latin and common names, as well as classification status, living habits, cultivation conditions and morphologic characters of the 19 aquatic species were studied. Moreover, present aquaculture status and the future development trend of shellfishes and crustaceans were also discussed. Keywords: Market, Crustaceans, Shellfish, Taxonomic Status 目录
