relationship between shrimp catches per unit effort (cpue) and satellite-based environmental parameters in persian gulf, bushehr provincial waters

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.
