As far as we known there are many scientists doing a lot of researches about animal physiologic regarding the influence and the result of different factors on fish metabolic rate. We can mention as an example: mass, temperature or chemical pollutants on metabolic rate. Regarding intraspecific variation, the reasons why it isn’t very well known less about factors causing. It is well known that feeding control influences the metabolism, they interlinked each other. During the last years we have been seeing a lot of climate changes which affect also the fish. Many areas like ecological niches, metabolic performance is definitively influenced by two very important factors like oxygen or temperature. Sometimes, when we have most important environmental variables, the answer for these variables is the temperature of the water and as an effect of this environmental variables we could see the metabolic rates of ectotherms. For this reason, wise minds studied besides water temperature the also the effects of this factor on fish metabolic rate. The also concluded that other environmental factors like oxygen and salinity play very important role as potential determinations of the fish metabolic rate. This review aims to integrate the currently existing data regarding the influence of environmental factors on metabolic rate in fish.
