摘要:

文章根据大型灯光罩网渔船调查数据和卫星遥感海面风场(Sea Surface Wind, SSW)、海表温度(Sea Surface Temperature, SST)和叶绿素a浓度(Chlorophyll a concentration, Chl a)资料, 基于广义线性模型(Generalized Linear Model, GLM)对北部湾渔业资源单位捕捞努力量渔获量(Catch Per Unit Effort, CPUE)进行标准化, 应用多元线性回归等方法, 对北部湾灯光罩网渔场的时空分布及其与海洋环境的关系进行了分析。结果表明, 北部湾灯光罩网渔场适宜SST为27~29℃, Chl a为0.5~1.5mg·m -3。较高资源量出现在10月份中上旬, 分布在18°—19°N及20°—21°N海域。北部湾灯光罩网渔场的时空分布与季风、19°N附近的暖水池和Chl a等环境因素有关。

Abstract:

We analyze the relationship between spatial-temporal distribution of light falling-net fishing ground and marine environments in Beibu Gulf, based on standardized catch per unit effort (CPUE) of fishery resources through generalized linear model (GLM) and multiple linear regression. The data used include light falling-net survey data and satellite remote sensing data, namely, sea surface wind (SSW), sea surface temperature (SST), Chlorophyll a concentration (Chl a). Results show the optimum SST and Chl a of light falling-net fishing ground in Beibu Gulf were 27~29 ℃ and 0.5~1.5 mg·m -3, respectively. Higher stock density appears in the first and middle 10 days of October, and distributed in the area of 18°—19°N and 20°—21°N. The spatial-temporal distribution of light falling-net fishing ground in Beibu Gulf is linked with monsoon, warm pool in 19°N, Chl a, and so on.

Key words: light falling-net, catch per unit effort, marine environments, remote sensing, Beibu Gulf
