TI Electrical stunning of fish: the relationship between the electric field strength and water conductivity

QU Aquaculture 2004; 241: 219-234

PT article

AB The electric field in water required to stun trout is investigated experimentally. The results show how the electric field depends on water conductivity. The electric fields in water required to generate permanent insensibility in trout following exposure durations of 15, 30 and 60 s are identified. A mathematical model of the electric field in the stunning tank is constructed and shown to produce results consistent with the experimental results. This simulation indicates that the electric field that occurs in the fish will vary little with variation of the fish position in the tank and fish size but that there many be a significant variation in the electric field experienced by individual fish in a high density cluster of fish if water conductivity is below 50 muS/cm or greater than 500 muS/cm.
