Fishing is usually a quiet and relaxing pastime but a couple of Russians have turned it into a more explosive affair.
The men were launched into the air in a frightening blast after dropping a grenade into the water next to their boat.
Video of the incident posted online shows one of the men drop the grenade into the water.
The grenade has barely begun sinking when it explodes sending the men and their equipment flying.
The men struggled to get up following the incident, but were apparently unharmed.
This dangerous type of fishing usually involves detonating the explosive deeper underwater to allow fishermen to collect dead fish as they float to the top.
