    On the effect of electrical field on Indian carps in captivity (2021)
    In:  http://aquaticcommons.org/id/eprint/16315 | 12051 | 2015-03-28 15:00:53 | 16315 | Society of Fisheries Technologists, India

    Description: Threshold current densities required for narcosis of fish in captivity differed in different species. Increased temperature of the water had greater effect on the fishes while changes of pH had no appreciable effect on narcosis in the fishes. Impulse currents of 50 V were found to have better effect on the fishes than continuous current of 180-220 V.

    On the response of Catla catla (Ham) and Cirrhinus mrigala (Ham) to the voltage gradient of electrical field (2021)

    Description: The threshold body voltage (voltage gradient between head and tail) required for first reaction, electro-taxis and electro-narcosis depended upon species, conductivity of the fish body, nature of current and wave shape. Larger fishes showed first reaction at a lower body voltage than smaller ones. All the three reactions were dependent on the accommodation of nerves to the electrical field and subsequent fatigue of the fishes. No significant change was observed in the period of narcosis and recovery after repeated stimulation.

    On the response of zooplankton in an electrical field (2021)

    Description: Zooplankton showed directional movement towards thepositive electrode in an electrical field till the current continued to flow. Examination of the plankton 24 hours after their exposure for one minute to different current densities showed considerable mortality, the percentage of which was more in the case of the larger size groups.
