摘  要：
根据2013年于南沙海域永暑礁手钓采集的金带齿颌鲷(Gnathodentex aurolineatus)样品,对其体长与体质量组成及关系、年龄组成、性比及性腺成熟组成、摄食强度等进行了初步研究。结果显示,7月和9月金带齿颌鲷体长分别为112~157 mm和120~162 mm,其体长分布、各体长组平均体长及平均体质量无显著差异(P>0.05)。7月和9月其体长与体质量关系生长参数b值分别为2.814 8和2.629 6。92个耳石中,年龄为1~11龄;7月优势年龄组为2~4龄,峰值为2龄;9月优势年龄组为3~6龄,峰值为6龄;其von Bertalanffy生长方程生长参数分别为:l∞=224 mm,K=0.028,t0=-27.282。7月金带齿颌鲷性腺成熟度包括Ⅱ期和Ⅲ期,9月则包括Ⅰ期、Ⅱ期和Ⅲ期。7月金带齿颌鲷摄食等级均以2级、3级和4级为主,9月则均以1级、2级和3级为主。随体长增加金带齿颌鲷雄性个体饱满指数降低。

摘  要：
Taking Glowfish( Gnathodentex aureolineatus) collected by handline in Yongshu Reef of Nansha area in the South China Sea in 2013 as samples,we studied the composition and relation of body length with body weight,age composition,sex ratio,gonad maturity composition and feeding intensity of G. aureolineatus. The results show that the ranges of body length of G. aureolineatus were112 ~ 157 mm and 120 ~ 162 mm in July and September,respectively,no significant difference was found in the body length distribution,average body length and weight( P > 0. 05). The growing parameters( b value) between body length and body weight in July and September were 2. 814 8 and 2. 629 6,respectively. The age range of 92 otolith identified was 1 ~ 11 year old. The preponderant class and peak of age were 2 ~ 4 and 2 years old in July,and 3 ~ 6 and 6 years old in September. The parameters of the von Bertalanffy growth function were as follows: l∞= 224 mm,K = 0. 028,t0=- 27. 282. The gonad maturity of G. aureolineatus were StageⅡ andⅢ in July,StageⅠ,Ⅱ and Ⅲ in September; the feeding stages of female and male G. aureolineatus were mainly at Stage 2,3 and4 in July and Stage 1,2 and 3 in September. The repletion index of male G. aureolineatus decreased with increasing body length.
