Abstract

Abstract

According to the catch data of Dosidicus gigas and the marine environmental data, i.e.,sea surface temperature (SST), sea surface temperature horizontal gradient (SSTHG), sea surface salinity (SSS), sea surface height (SSH), chlorophyll (Chl-a) concentration in the fishing ground outside EEZ of Peru during 2003 to 2007, the method of principal component analysis was used to determine the weight of environmental factors, the weighted sum method and the geometric mean method were used to model habitat suitability index (HSI), and the optimal model was selected for an empirical analysis. The results show that the highest weight with the environmental factors for SST, the smallest for the Chl-a concentration. The high value of HSI estimated from the weighted sum method and the geometric mean method is generally distributed in the waters outside the 200 n mile exclusive economic zone. Based on the statistical comparison, the weighted sum method is better than the geometric mean method in the HSI calculation.The empirical analysis also shows that the weighted sum for estimating HSI is better suited to speculate fishing ground in 2008 since the average yield increase with the higher HSI values, which suggests that weighted sum method for estimating HSI can be used to predict the real-time dynamic fishing ground of Dosidicus gigas. The results also reveal that the putative HSI is closely related with marine environment, and the area with the HSI value above 0.8 is located at the mixture water.
