and this comes as a consequence of various anthropogenic activities. The dissolution of CO , which has 2
the largest share among the greenhouse gases in terms of contribution in global warming, threatening
the continuation of life on earth. Changing climate is of vital importance because of major impacts by
influencing water resources and agricultural economy. Climate change stresses exert complex pressure
on aquatic biodiversity and natural aquatic resources. Water temperature change may alter the
metabolism and physiology of aquatic animals thereby affecting the growth, fecundity, feeding
behavior, distribution, migration and abundance of fish as well as other aquatic animals.
