Monitoring of surrogate zoonotic parasites of Anisakidae and Echinobothrium deeghai as bioindicators by application of energy dispersive X-ray microanalysis (EDXMA)

AbstractThe unique characteristic of quickly altered but stable response by helminth parasites against metals and elements in a variety of aquatic ecosystems because of pollution conditions merit these as significant markers of fish health as well as of marine and freshwater ecosystems. Biomagnification of toxicants released in aquatic reservoirs by human mediated processes incorporating mining in coastal zones, industrial and agricultural inputs contributed to damaging consequences of human health due particularly to human consumption of edible fish and other biota that are exposed to contaminants in aquatic ecosystems. The metals and elements analysed could be arranged in decreasing order of concentration were found to be, P  >  Ca >  Cd >  Mn >  Hg >  Pb >  As >  Zn >  S >  Fe >  Al >  Cr >  Mg >  Cl. The association betweenEchinobothrium deeghai andRotundocollarette capoori demonstrated surrogate relationship to drain in highly toxic heavy metals like Hg, Cr, As, Cd, from the ambience in the micro-environment of cestodes and nematodes and thus acted as benefactors for the life of the brackish water oceanodromous fish.
