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
