Effect of different filling medium on cooking time and quality of yellowfin tuna during canning was assessed. Lag phase for heating was lowest for tuna processed in sunflower oil whereas lag factor for cooling was lowest for tuna in groundnut oil. Reduction in total process time was noticed in tuna processed in sunflower oil owing to faster heating...

The Wayanad Mahseer Neolissochilus wynaadensis (Day, 1873) is an endemic cyprinid fish that occurs in the upland streams and rivers of the southern region of the Western Ghats.

We collected 17 individuals of C. gariepinus ranging in size from 200 to 750 mm from different locations in the...

Soft shell turtles are among the most threatened groups of freshwater animals that are in need of urgent conservation attention.
