An investigation of the climate change effects on Carangidae stocks in the Sistan-Baluchestan waters

In this research, the relation between the time series Carangid fishes (Carangidae) CPUE data in Sistan-Baluchestan waters with the environmental effective data including sea surface and air temperature, chlorophyll a, evaporation rate and rainfall as parameters of climate change indicators have been studied monthly during 2007 – 2018. GLM and GAM regression were used for data analysis. The results showed significant decrease in carangid species. In this regard, the two factors of SST and air temperature have had an increasing and both SST and air temperature showed significant relationship with Scomberoides commersonianus and other carangid species CPUE stocks. Finally, it seems that in order to maintain the carangids fish stocks due to the various effects of climate change and environmental factors, and human activities particulary, need to reform fisheries regulatory management.
