The Nizhny Novgorod Region is imposing a ban on burbot fishing from December 15 to January 31 to protect the fish population during the spawning season. Burbot is the only cod species in the region and has commercial value. The region will increase control at places where the fish accumulate and impose a fine of 500 rubles for each illegally caught burbot. Violators may face a fine of two to five thousand rubles or criminal liability. A separate ban on fishing in wintering pits has been in place since October 1 and will continue until April 30.
