基于栖息地指数模型的摩洛哥底拖网渔场研究
Study on Fishing Ground of Bottom Trawl Based on the Habitat Suitability Model in the Coastal Waters of Morocco
摘要
Abstract
The coastal waters of Morocco is the main fishing area of Chinese bottom trawlers. The current study investigated the fishing ground of Morocco bottom trawl fishery based on the fishing statistical data of bottom trawlers from Shanghai distant-water fishery company during 2012 to 2015 and the satellite remote sensing data such as sea surface temperature(SST),Chlorophyll-a(Chl-a) and sea surface height anomaly(SSHA)using the method of habitat suitability index including the geometric model and arithmetic average model. The monthly suitability index is established based on the relationship between fishing nets and SST,SSHA,Chl-a and sea depth, which were various among different month for appropriate scope of marine environment. Based on AMM model, the percentage of fishing nets and catch reached 65.92% and 67.57% of the total in the fishing areas in which HSI is greater than 0.6. Based on GMM model, the percentage of fishing nets and catch only reached 44.78% and 49.60%of the total in the fishing areas in which HSI is greater than 0.6. The results indicated that AMM model is more suitable for forecasting fishing ground in Moroccan bottom trawl fishery.关键词
