hello every one. I have measured lead, cadmium and chromium in fish muscles and my result showed a reduction of heavy metals concentrations in females .is it possible that heavy metals have been eliminated in fish eggs?

If it is a controlled experiment, then it is necessary to analyze metal concentration on the eggs (collection required). However, a complex interaction may avail metal affinity to the eggs due to the presence of specific proteins.
Fish eggs are vital for continuity of population and susceptible to heavy metal pollution. Heavy metal concentrations in seawater is efficient on hatching achievement of fish eggs. Most of marine fish produce their eggs and spermatophores to marine water freely and fertilization happens in seawater. whilst heavy metals in seawater go over defined limits, they can influence the physiology of eggs and larva
