Abstract
This study aims to shed light on the fact that pollution and climate changes has an adverse effect on both cold water and warm water fishes. It is a known fact the capability of a fish to adopt or accept the changes in environment is a species specific thing, if there comes a case of rapid change in temperature, there are almost some situation which will come out as an outcome i.e. it could result in extinction because of the thermal stress or it may go under the process of genetic changes within some limits based on the natural selection process. There is a possibility that alteration in the dominance of species will probably occur, for the reason that species are adaptive to certain range of thermal, spatial and temporal characteristics. This will happen because of the climate induced shifts. May be it will affect the route of dispersal. Keywords: Climate Change, Extinction, Cold Water Fish, Warm Water Fish, Pollution.
Introduction
Temperature of water regulates the food web of a river and its network, this process in itself is complex by nature, experts believe that thermal regime in rivers as well as stream ecosystems are profoundly significant to fishes and other water and marine organism this is for the reason that most of these organisms are ectotherms in nature hence their physiological processes is unswervingly controlled by temperatures of the ambient atmosphere. As an end result it is seen that the temperature of these water stream evidently governs the distribution and quantity and type of species along spatial and temporal scale, any change or modification in temperature put direct effect on marine life. Temperature is one factor that regulates or governs that which organism will thrive or which will reduce in size and number, as for each aquatic organism there is a thermal death point determined already, temperature mainly effects the cold blooded or poikilothermic species. Fishes are supposed to be poikilothermic in nature because not only its survival but also the growth and reproduction of these organism has acute temperature range, in order to survive each of these organism need to be favored by the suitable temperature. This is because temperature influence most of the activities of an organism such as enzymatic reactions, hormonal reactions, nervous control and digestion, if to suffice it won’t be wrong stating that all of aspect of an organism’s performance and behaviors are governed by temperature.
