　　根据2011年春季(4月、5月、6月)对浙江南部近岸海域进行的共3个航次的底拖网渔业资源调查资料,对该海域口虾蛄(Oratosquilla oratoria)生物量的时空分布进行了分析。结果表明,4-6月,在月间分布上口虾蛄的生物量呈逐月下降的趋势,但各月间不存在显著性差异；在空间分布上大多数站位的生物量均较低(<150kg/km2)；生物量重心位于27°33′N-27°55′N、121°20′E-121°38′E之间海域。各月相对高生物量(>150kg/km2)的空间分布与该月底温与底盐的变化相关。另外,随着月平均底盐特别是平均底温的升高,口虾蛄呈现逐月由较深海域向较浅海域移动的趋势。

Based on three surveys carried out by bottom trawl in spring (April, May and June) of 2011, the spa-tial-temporal distribution of the biomass of Oratosquilla oratoria in the coastal waters of South Zhejiang was analyzed. Two methods including sweep area method and analysis of variance (ANOVA) were used here. The results showed that:for temporal distribution, the biomass of O. oratoria decreased from April to June, but there were no significant differences between them. For spatial distribution, the biomass of most of the survey positions was lower (<150kg/km2). The biomass center located in 27°33′N-27°55′N, 121°20′E-121°38′E. Monthly distribution of relatively higher biomass related to the bottom temperature and salinity. Otherwise, O. oratoria moved from deeper waters to shallower waters from April to June with the increasing of the average salinity, and especially of the average temperature.
