Abstract

This study conducted to analyses time series data of stingrays catch per unit effort (CPUE (kg/day) data from 2007 to 2018 from fishing grounds of the Persian Gulf and the Oman Gulf. Data from sea surface temperature, chlorophyll a, evaporation, wind speed, rainfall and air temperature were also considered in the analysis. In order to investigate ecological status, regression models, neural networks and decision tree used to analyses data. According to the results, biomass of the stingrays stock showed different status in various parts of the water body and results revealed that stingrays stock significantly related with wind speed and sea surface water in Khuzestan waters, chlorophyll a in Bushehr waters, air temperature in Hormozgan waters and sea surface temperature in Sistan and Balouchestan waters. Technically, temperature was the constant significant coefficient in all parts of the study area. To sum up, effect of climate change on stingray’s biomass was sensible according to the results of this study and was vary between study sites.
