Effect of the static electric field of the anticorrosive protection of oil piрelines crossing the Ob on the behavioral response of fish was investigated. It is shown on the basis of calculations and measurements that the electric field strength at the level of the bottom is 0,6 V/m, at a depth of 2 m from the surface it is 0,4-0,1 V/m and spreads at a distance of 50-100 m from the oil piрeline. It is established that the electric field of oil piрelines decreases the migration activity of fish, which causes an increase in fish number in the sector of increased electric field strength.
