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.</span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:120%"><span style="font-family:Calibri,sans-serif"><span style="font-size:12.0pt"><span style="line-height:120%"><span new="" roman="" style="font-family:" times=""><span style="color:black">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.</span></span></span></span></span></span></span> Shrimp, Catch per unit effort, Environmental parameters, Satellite data, Bushehr, Persian Gulf 372 386 http://jifro.ir/browse.php?a_code=A-10-26-2&slc_lang=en&sid=1 Kh.
