Oxygen deprivation caused due to water logging during flood could affect physiology of earthworms with significant increase in oxidative stress. This study reports the effects of short-term water logging of 12h and 24h duration with different water column heights and consequent depletion in oxygen level in water on survivability, tissue protein, lipid peroxidation (LPX) levels and activities of the enzymes, lactate dehydrogenase (LDH) and catalase (CAT) of the earthworm, Eudrilus eugeniae. The survivabilities were 30% and 15% under 5cms (T1) and 10cms (T2) water columns after 24h. With depletion of DO in the water, tissue protein of the earthworm indicated significant increase up to 12h but there after declined sharply up to 24h. Significant increase in LPX level, LDH and CAT activities were observed after 12h and 24h. The biochemical parameters of the animal showed significant variation between treatments and was found to be negatively correlated with DO of water column. It was concluded that hypoxia due to short-term waterlogging could seriously impair the metabolism and survival of earthworms. [ABSTRACT FROM AUTHOR] |
