The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish o...

the effects of dietary nucleotide (nt) were evaluated on some serum biochemical parameters and acute stress responses of the catfish (pangasianodon hypophthalmus). five experimental diets including 0, 0.25, 0.5, 0.75, and 1% nt were supplied to catfish fry for 10 weeks. at the end of the experiment, fish fed the control and 1% nt diets were subjected to handling and crowding stress. the results...

Abstract A 3-month experiment was designed to investigate the effects of different stocking densities on growth, stress markers, intestinal digestive enzymes, hepatic antioxidant biomarkers, serum immunity, and survivability striped catfish, Pangasianodon hypophthalmus . The relationship between fish water quality parameters also assessed. Healthy ( n = 1260 individuals, 17.52 ± 0.20 g) were ra...

the present experiment was undertaken to study the effect of different dosages of β-glucan on the growth, survival and physiological responses in juvenile striped catfish ( pangasianodon hypophthalmus ). over nine weeks of feeding fish with a diet containing 0, 0.5, 1 and 2% β-glucan (as control, g1, g2 and g3 group, respectively), some blood parameters such as serum lysozyme activity, total pr...
