The objective of this study was to evaluate the eff ect of anthropogenic pollution on DNA
damage and the fatty acid profi le of the bottom dweller fi sh ( Cirrhinus mrigala ), collected from the River
Chenab, in order to assess the eff ect of the toxicants on the quality of the fi sh meat. The levels of Cd, Hg, Cu,
Mn, Zn, Pb, Cr and Sn and of phenols from this river were signifi cantly higher than the permissible limits
set by the USEPA. Comet assays showed DNA damage in Cirrhinus mrigala collected from three diff erent

The eastern and southern parts of the Faisalabad
city produce considerable quantities of industrial and municipal
pollutants, much of which is drained into the River
Chenab, reducing the productivity of fauna and flora in the
river. This study was aimed to determine whether cysteine is
useful as a biomarker of exposure to polluted fresh water. The
amino acid profile of fish muscle was analyzed by paper chromatography
in Cirrhinus mrigala and Labeo rohita from the
River Chenab to determine habitat related variations due to the

In this study, the ontogeny of the digestive tract was studied histologically in striped murrel Channa striatus from

hatching to 25 days post-hatching (DPH). At hatching, the digestive tract of striped murrelconsisted of a straight tube

dorsally attached to the yolk sac. St 2 DPH, the mouth opened, oral valves were visible and taste buds were detected

between 2 and 3 DPH. During this period, intestine was differentiated into the anterior and posterior intestine, and the

Feeding ecology of any species can help us to understand its natural history, ecological

requirements and approaches involved in searching for food. Feeding ecology and sexual dimorphism

in the horned viper, Cerastes cerastes gasperetti collected from the Al-Thumama area, central

region of Saudi Arabia was described. The gut content of Cerastes c. gasperetti mainly consisted of

rodents (70%) in addition to arthropods (15%) and lizards (10%). Least sexual size dimorphism
