عنوان انگلیسی Relationship between shrimp catches per unit effort (CPUE) and satellite-based environmental parameters in Persian Gulf, Bushehr provincial waters
چکیده انگلیسی مقاله In the present study relationship between shrimp catch per unit effort (CPUE) and satellite-based environmental parameters, chlorophyll-a (Chl-a) and sea surface temperature (SST), was investigated in 27 stations in Bushehr provincial waters in the geographical position from E 50˚ 44´ and N 28˚ 59´ to E 51˚ 40´ and N 27˚ 33´, in July 2017 and July 2018. SST and Chl-a data were extracted from +ETM Landsat 7 sensor and Modis Aqua (EOS PM) satellites images. Four research surveys were conducted using a traditional vessel to record local physico-chemical parameters of water and estimate shrimp catch per unit effort (CPUE) in studied stations.The results of linear regression analysis and correlation coefficient showed a negative and strong relationship between SST- Chl-a overlap value and shrimp CPUE in waters of Bushehr province (r = -0.84), while weak negative and positive relationships were observed between SST and chlorophyll-a with shrimp CPUE with r = -0.34 and 0.03, respectively.
