Morphological Analysis of Statoliths for Uroteuthis chinensis in the North Area of South China Sea
摘要
Abstract
Uroteuthis chinensisis an important species of cephalopodin the South China sea. The statolith is the important hard tissue for cephalopods, which have the stability of the morphological characteristics, corrosion resistance and other characteristics, and have become one of the important research materials of cephalopod in the field of fishery biology and marine ecology. According to statolith of Uroteuthis chinensis collected during September 2015, the external morphological parameters are measured.The results showed that the primary morphology parameters of statoliths are total statolith length (TSL), Mantel length (RL), maximum statolith width (MW) and wing width (WW), respectively, andthese 4 primary morphology parameters could be used as typical morphological characteristics of statolith ofUroteuthis chinensis.The relationship between primary morphology parameters of statoliths and its size and sexual maturity are analyzed, and the models between the primary morphological parameters and length and weight are established. The relationshipsbetween TSL, RL and ML could be described with linear functions, while the relationships between MW, WW and ML could be described with power functions. The relationship between TSL, RL, WW, MW and weight could be described with linear models based on the AIC value. It is also found that the effects of sexual maturity and size on statolith of morphological parameters MW/TSL are not significant (P> 0.05). This research could provide basic information on population discrimination and growth of Uroteuthis chinensis.关键词
