STUDY ON TOXICITY OF DIFFERENT CONCENTRATION OF HOUSEHOLD DETERGENT “TIDE” ON OXYGEN CONSUMPTION IN FRESHWATER FISH LEPIDOCEPHALICHYTHYES THERMALIS
Shaikh Nusrat Jahan* and Nisar Shaikh
ABSTRACT
Water is one of the most important and precious element on the earth
surface which is very essential for life. Lepidocephalichythyes
thermalis is one of the most common edible fish available in the local
market of Bhiwandi was selected in the present study to analyse the
effects of tide detergent on oxygen consumption capacity of the fish in
two sublethal concentrations. The amount of dissolved oxygen
consumed by fishes was determined using Winkler’s method. The
average mortality (LC50) was determined by Finney Probit Analysis.
According to probit the 50% mortality values of detergent tide for 24,
48, 72 and 96 hrs were recorded as 42 mg/L, 39 mg/L, 36 mg/L and 32
mg/L respectively. The Fishes were exposed to sublethal
concentrations (13 mg/L) 1/3rd and (3.9 mg/L) 1/10th the LC50 values of tide for 48 hrs. The
oxygen consumption has fluctuated with both the sublethal concentration with increase in
time.
Keywords: Detergents, Tide, Dissolve oxygen, Lepidocephalichythyes thermalis, fish.
