| 摘 要： | 观察了采集于江苏南通近海的69只中国明对虾的眼柄微结构，分析了其体长和体质量的生长。结果显示，眼柄由表层、色素层、钙化层和膜层4个部分组成。眼柄内存在明显的生长宽带和细纹，其中宽带数0~1个，细纹数27~37个。最小AIC法拟合分析显示，中国明对虾体长、体质量的生长与眼柄细纹数都呈显著的Logistic关系。研究表明，中国明对虾眼柄中的宽带与其年龄相关，细纹可用来分析中国明对虾的生长，而细纹的形成周期是否与个体差异、生长环境差异等相关还需要进一步验证。

| Abstract: | It is known to all that age and growth study of crustacean is a problem. However, this problem has been solved to some extent as growth increments were found in hard structures such as eyestalk and gastric mill of crustacean. Fenneropenaeus chinensis as one of important economic shrimp, the study of age and growth has been widely concerned. This paper collected 69 F. chinensis from the coastal waters of Nantong, Jiangsu Province. The microstructures of eyestalks of these F. chinensis were analyzed, and the relationship between growth bands of the eyestalks and the weight of F. chinensis was studied. Research shows that the eyestalks consists of four parts: epicuticle, exocuticle, endocuticle and membranous layer. Eyestalk has growth bands and growth increments obviously. Among 44 clear microstructure samples, there are 33 samples with 0 growth band, and 11 samples with 1 growth band. The number of growth increments in one growth band is 25 to 37. The number of growth increments and the length and weight of F. chinensis showed Logistic relation. We conclude that the formation of growth bands of eyestalk in F. chinensis is yearly. However, the formation of growth increments is not daily. Whether the formation period of growth increment is different from the individual differences and the growth environment differences of F. chinensis needs further experimental verification. The results not only lay the foundation for the future identification of F. chinensis, but also provide a new method for the domestic identification of shrimp and crabs and their growth. |
