Abstract

The study was aimed to estimate the current status of physico- chemical characteristic of Madavarvalagam tank (Srivilliputhur) located in Virudhunagar District, Tamil Nadu. Monthly changes in physico- chemical parameters such as temperature, pH, dissolved oxygen, free CO₂, total alkalinity, chlorinity, salinity, total hardness was analysed. The present study, observed that 9 species of zooplankton belonging to four major groups i.e. Rotifera (3 species), Cladocera (1 species), Copepod (4 species) and Ostracoda (1 species).

G. Seetha lakshmi and R. Arthi Manju

Abstract

The present study has been carried out the effect of medicinal plants like Cynodon dactylon and Cassia auriculata on different concentrations of formulated diet against Aeromonas hydrophila infection on Channa punctatus. The parameters such as, anti-protease activity, total heterotrophic count and antioxidant enzymes were studied. The results of feeding the fishes with experimental diet has significantly (p<0.05) enhanced the serum anti protease and total heterotrophic count than fishes fed with control diet.

Keywords: Channa punctatus, Cynodon dactylon, Cassia auriculata, Aeromonas hydrophila, Antiprotease activity, Total Hetertrophic count; Antioxidant enzyme.
