초록
The data Presented in this Paper, on the body and Jumping voltage of Penaeus japonicus BATE, are part of a current study on shrimp behaviour in order to improve fishing efficiency of the fishing gear. The experiments concerning electrical stimuli was mostly carried out at the Marine Laboratory of Busan Fisheries College in 1972. The following are the results obtained from the present investigations : 1. When the voltages between a pair of electrodes were fixed constant, the voltage drops between them showed almost constant electrical field. 2. Threshold voltages of the animals varied with body direction to the electrical field, i. e., 200 -500 mV for parallel, 500-1400 mV for vertical and 300-800 mV for diagonal (
