Study on Otolith Morphology of Chelidonichthys spinosus in the Qingdao Coastal Waters
摘要
Abstract
Monthly variation in otolith shape of Chelidonichthys spinosus in the Qingdao coastal waters was investigated from June to December 2002. A toal of 286 samples were collected from the fishing catches for this study. Otolith length, width, perimeter, area, rectangularity and circularity as well as some Fourier descriptors were analyzed. The results indicted that the otolith was round or quadrangular with a nick in the anterior part. All otolith measurements except for OL/OW(i.e. length, weight and area) were significantly correlated to the standard length of the fish. Otolith shape significantly altered with monthly growth of the fish. Multivariate analysis and canonical discriminant function analysis found that the morphological development of the otoliths was compartmentalized in to three phases: June, July to September and October to December.关键词
