The marine ecosystems are getting warmer and less oxygen and eventually becoming more acidic, there is also clear evidence that fish species are threatened by capture fishery on a regional and global scale. For this reason, the assessment of the inherent vulnerability of major species of catches is of great importance. There are several indicators of vulnerability classifications, and one of the most important is the biological and ecological characteristics of fish. This research tries to classify their vulnerability by examining the demographic parameters of major catch fish species in southern Iran and the Intergovernmental Panel on Climate Change (IPCC). In this study, according to the vulnerability index, which has values from 0 to 100, the following classification was performed. Low vulnerability fish (liza kluzengerii, Nemipterus japonicas) with values from 0 to 25, the medium vulnerability (Platycephalus indicus, Psettodes erumei) with values of 25 to 50, the high vulnerability (Pumpus argenteus, Tenualosa ilisha) 50 to 75, and very high vulnerability (Argyrosomus hololepidotus, Rhynchobatus djiddensis) 75 to 100. Undoubtedly, this type of classification can be useful for fishery managers and fishery managers and help them to better understand species and planning appropriately. In fact, we will build on this approach and have a better understanding of species variation and climate change, and will examine the risk of fish species being confronted with and their compatibility.
