Meat quality of three different weight groups of farmed and wild Cyprinus carpio was analyzed in
this study. Proximate composition of meat and dressing losses of wild and farmed C. carpio of three different weight
categories was analyzed in this study. The farmed raised C. carpio of three different weight categories designated as
F1 (600-1000 g), F2 (1100-1500 g) and F3 (1600-2000 g), were procured from a commercial fish farm. Concurrently,
wild C. carpio of three different weight categories designated as W1 (600-1000 g), W2 (1100-1500 g) and W3 (1600-

Specimens of Clarias gariepinus were treated with lethal (70, 75, 80, 85, 90, and 95 mg/L)
and sub-lethal concentrations (8, 12 and 16 mg/L) of uranyl acetate, a low-radiotoxicity uranium salt. The
LC 50 value was registered as 81.45 mg/L. The protein and glycogen concentrations in liver and muscles
were decreased in the fi sh exposed to sub-lethal concentrations. The red blood cell (RBC) and white blood
cell (WBC) counts, haemoglobin (Hb) concentration and haematocrit (Hct) values were decreased. Diff erent

Pesticides widely used for agricultural purposes are carbamates, organophosphates as well as organochlorines. Among these pesticides, organochlorine compounds have been extensively used to control disease vectors as well as agricultural pests. The objective of this experiment was to study the chronic effect of a commercial formulation of profenofos on acetylcholinesterase (AChE) and butylcholinesterase (BuChE) activity in various tissues in Catla catla, Labeo rohita and Cirrhinus mrigala fingerlings was investigated.

The concentrations of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn was determined in the
muscle, gills, liver, and an intestine of the Clarias gariepinus from the Wadi Hanefah (WH), Saudi
Arabia. The accumulation of metals differed significantly (P<0.05) in the muscle and the skin. Zn
were most abundant (55.84±4.85μg/g dry weight) and Pb was in a minimum quantity (0.22±0.02
μg/g dry weight) in the muscle. The similar pattern of elemental deposition was observed in the skin
