L. John et Tv. Fernandez, INCIDENCE OF TRACE-METALS IN SCYLLA-SERRATA, AN EDIBLE CRAB FROM ASHTAMUDI ESTUARY, INDIA, Journal of environmental biology, 19(2), 1998, pp. 99-106
Trace metals such as zinc, copper, iron, lead, nickel and cadmium in d
ifferent tissues like gills, hepatopancreas, gonads, chelate and abdom
inal muscles of different sizes and sexes (juveniles, subadults, adult
males and females) of Scylla serrata were analyzed. All the five meta
ls (except zinc) showed the maximum deposition in the gills followed b
y hepatopancreatic tissue. Concentration of zinc was highest in the ed
ible muscles. Another equally important finding is that the incidence
of non-essential metals such as nickel and cadmium were minimum in juv
eniles and maximum in adults.
