Aquatic toxicity impacts on behaviour and survival of fresh water fish: A reviewAuthor(s):
Kavya Tanna, Dr. Dhara Bhavsar and Dr. Archana MankadAbstract:
The earth has only 3% of freshwater out of all the water available on the earth and only 1.2% water can be utilized as drinking water. It is thus quiet clear that freshwater ecosystem consists only 3% of all ecosystems on earth. Aquatic toxicity is the measure of contamination in aquatic ecosystem and its impacts on inhabiting organisms. The toxics generally found in aquatic ecosystem are metals, fertilizers, micropollutants and macropollutants. The sources of these pollutants are mostly due to industrial discharge, run off or anthropogenic activities. The toxic effects are lethal and sub lethal both, which may change development, growth rate, reproduction, biochemistry, physiology and behaviour. The toxics are added to water body as a result of runoff residue which is extremely hazardous and harmful to fish. There are emerging concerns about these toxics and its hazardous impacts but comparable research is not reported in freshwater environments. Present study aims to investigate the occurrence and impact of toxics on aquatic species. The importance of such fishes are food web management, regulation of carbon flows, sediment strength and ecosystem links. Hence, freshwater fish populations should be protected and preserved in natural habitat. The purpose of the paper is to highlight the contaminants in freshwater and their impact on adjoining species; responding with different behavioural changes as we are closely associated with it.Pages: 235-243 | 269 Views 40 DownloadsDownload Full Article:
