Laboratory experiments have shown high accumulation of pollutants.
e.g. heavy metals and insecticides in the liver of Tilapia zillii
Gerv .• living in fresh or saline water. Meanwhile. the field
applications demonstrated a change and increase in the liver
conditions when the fish lives in polluted water. This could allow
the hepatosomatic i~dex to be considered as an indicator of aquatic
environmental pollution with heavy metals and insectisides.
