CLIMATE CHANGES AND ITS IMPACT ON FISH WITH REFERENCE TO ANTIBIOTIC RESISTANT ENTERIC BACTERIA AND HEAVY METAL ACCUMULATION: A HUMAN HEALTH

Fresh fish (Mugil cephalus) is a very important source of protein to the population in our country. This fish may harbor Salmonella sp. It may be a source of pathogen to human being. A total of 20 samples (20 muscles and 20 gills) were analyzed. The isolates were exposed to 5 different antibiotics. Most of the isolated were resistances to at least one of the antibiotic. This is a clear indication that sewage effluent causes contamination of marine wildlife. Investigation on the accumulation of heavy metals (cadmium, copper and chromium) was carried out commercially important fish (Mugil cphalus). The accumulation was observed in tissues of muscles and gills. The result revealed that the copper and cadmium concentration were highest in the muscle and gills. In the muscle and gill of Mugil cephalus the order of accumulation was Copper>Cadmium>Chromium. Key words: Salmonella sp, Heavy metals, Fish, Muscles and Gill
