摘要:: 根据2014—2016年福建厦门湾海域（118°E～118.4°E，24.4°N～24.6°N）渔业资源监测调查资料，对采集到的384尾条纹斑竹鲨(Chiloscyllium plagiosum Bennett,1830)测量其全长、体重等生长参数，利用ELEFAN技术和Pauly经验公式对厦门湾条纹斑竹鲨的全长-体重关系、Von Bertalanfy生长方程和死亡参数等生物学特征进行计算。结果表明：2014—2016年厦门湾水域条纹斑竹鲨，平均全长为318 mm，优势全长组为250~300 mm（占比为28.0%）；平均体重179 g，其中占比最高（17.4%）的体重组为40~60 g；条纹斑竹鲨全长-体重之间的关系式为W=5×10－6L2.9435，Von Bertalanfy生长方程的参数分别为L∞=94.5 cm，K=0.45，t0=-0.2349 a-1，生长拐点的年龄为2.1643龄；总死亡系数(Z)为1.53,自然死亡系数(M)为0.6869,捕捞死亡系数(F)为0.8431，渔业资源正处于过度捕捞状态。

Abstract:: Based on the survey data of fisheries resources in Xiamen Bay of Fujian (118°E to 118.4°E，24.4°N to 24.6°N)from 2014 to 2016，the growth parameters of total length and total weight of 384 striped bamboo sharks were measured.The biological parameters were calculated and analyzed by the ELEFAN technique and the Pauly formula.The results showed that the average total length of the striped bamboo sharks was 318 mm，the dominant total length group was 250-300 mm，occupied 28.0%，the average total weight was 179 g，the weight dominant group was 40-60 g，and the proportion was 17.4%.The relationship between the total length and weight of the Striped bamboo shark is W=5×10-6L2.9435，and the parameters of the V-B growth equation are L∞=94.5 cm，K=0.45， t0=-0.2349 a-1，and the inflection point of growth was 2.1643.The total mortality coefficient (Z)was 1.53，the natural mortality coefficient (M)was 0.6869，the fishing mortality coefficient (F) was 0.8431，and the fishery resources were being overfishing.
