摘　　要：根据2022年8月—2023年4月福建漳浦近海张网作业调查数据,对主要渔获物368尾口虾蛄(Oratosquilla oratoria)的体长、体质量、摄食强度、雌性卵巢发育程度、雌雄比例和肥满度等生物学特征进行了研究,以期为口虾蛄资源的利用和保护提供参考。研究表明,张网作业渔获物中,口虾蛄雌雄比例为1∶1.115,口虾蛄体长优势组为110~130 mm,体质量优势组为15.0~25.0 g,雌、雄样品平均体长、平均体质量差异均不显著(P>0.05)。口虾蛄体长和体质量关系为W=2.140×10^(-5) L^(2.882)(R^(2)=0.946,n=368)。雌性口虾蛄性腺成熟度在Ⅰ~Ⅲ期之间,Ⅲ期个体主要出现在2—4月。口虾蛄摄食等级平均为1.44级,其中1级最多。口虾蛄群体肥满度指数平均值为1.226,雄性略大于雌性。Mantis shrimp(Oratosquilla oratoria),the main catches of stow net fishing vessel in Zhangpu,Fujian Province,were followed and sampled monthly from August 2022 to April 2023.A total of 368 samples were used to determine the body length and body mass,to characterize the feeding intensity and female ovarian development,and to calculate the ratio of males to females in the catch,in order to analyze the fishery biology of O.oratoria.The results showed that the ratio of female to male was 1∶1.115 in the catch of O.oratoria,the dominant body length group was 110-130 mm,the dominant body mass advantage group was 15.0-25.0 g,and there was no significant difference in average body length and average body mass between male and female samples.The relationship between body length and body mass was W=2.140×10^(-5) L^(2.882)(R^(2)=0.946,n=368).The gonadal maturity of female O.oratoria was between stageⅠ-Ⅲ,and stage III individuals mainly appeared from February to April.The average feeding grade of O.oratoria was 1.44,of which grade 1 was the most.The average annual condition factor index of O.oratoria was 1.226,and the male was slightly larger than the female.
