    Changes in Oxygen Uptake in Mullet, Liza parsia (Hamilton-Buchanan) Exposed to Dichlorvos
    (Society of Fisheries Technologists (India)Cochin, 1993) Mohapatra, B.C; Noble, A
    For acute study on oxygen consumption Liza parsir were exposed 96 h to 0.482 ppm of organophosphate insecticide, Dichlorvos 76% (96 h LC so value) and for sublethal effects to I/S, 1/10 and 1/15th of it for 15, 30 and 45 days. Initially the consumption of oxygen increased. But it was followed by decrease in acute experiment. In sub-lethal exposures the oxygen consumption remained high without decrease. However, the increase was higher in lower concentrations. 'l11e experiments were conducted ln I brackishwater medium of salinity 10.0 ;l: 1.0%°, temperature 27.5 i 1.5 °C and pH 6.0 1 0.5.
