Tropical freshwaters support an immense diversity of fishes and invertebrates but are understudied in comparison to temperate systems. This is especially true headwater streams, as only a small number studies has assessed the trophic dynamics underpinning food web structure these streams. We used stable isotopes carbon, nitrogen hydrogen determine resource use dominant invertebrate guild seven ...

For the purpose of cytological studies and work out the correlations among the teleost fish species, some 5 fish species are selected viz Notopterus notopterus, Labeo rohita, Tilapia mossambica, Clarias batrachus, and Channa gachua. The observations regarding hematology are made from peripheral blood by traditional staining method while histological and cytological studies are done from the sec...

Channa punctatus is a freshwater fish belonging to family Ophiocephalidae. This fish is available in almost all over the country. In present communication molecular study of COI region of mitochondrial gene was done to find out intraspecific differences in genome of Channa punctatus habitating in different states of India having variable environmental conditions. Result showed minor variations ...

Pesticides have an innate capacity to cause damage to biological system. Considering above fact the present study deals with the effect of the insecticide malathion on histological and biochemical study on cardiac muscle tissue in Channa punctatus. In present study effect of sub lethal concentration (0.8 ppm) of malathion on protein, lipid and glycogen content and histopathological changes in h...
