Commercial fisherman Allan Marsden is pictured throwing a bear banger into a group of sea lions in the Strait of Georgia.

A danger to the fishing industry?

Marsden says he used the bear banger to disperse the sea lions not to kill them.

"You know we're not out there trying to kill the sea lions, we're not out there looking for sea lions, we'd rather if they weren't here,"said Marsden.

"They are here, we're trying to make a living, and we're just trying to figure out a way to deal with both issues."

Marsden said he took part in the video to educate the public thatsea lions pose a threat to the fishing industry.

The fisherman said he was in the area, on the water looking for herring samples to check the percentage of roe in the fish, but the sea lions were driving the herring away from the surface.

Marsden said the explosive wasneeded to ensure the safety of fishermen, adding he was once injured by a sea lion that approached his boat.

"I got bit before," hesaid.

"I'm lucky that I'm not in a wheelchair or worse, dragged overboard and drowned by the sea lion,"Marsden said.

The video drew mixed reaction on Facebook. Some showed support for Marsden's action,saying itsheds light on how sea lions can interfere with fishing activities.

Charges may be laid

In a statement, the Department of Fisheries and Oceans said it is reviewing the incident, noting it's against federal regulations to disturb, harm or kill marine mammals.

"Charges may be laid," the statement said. The DFO statement noted it is illegal to disturb or harm marine mammals by any means, including the use of acoustic deterrents.

Andrew Trites, a marine mammal researcher at the University of British Columbia, said he was shocked by the cruelty of the incident.

"Throwing a stick of dynamite next to the head of an animal, you're going to blow out its hearing. If it's near its eye, you're going to blow the eye out,"Trites said.

He said the bear bangers are meant to be used at some distance from the animals, just to scare them off, but not to harm them.

"I know I've heard them say 'well it doesn't hurt the animal.'Well if that's the case I would challenge them to hold that stick in their hand, light it and let's film it,"said Trites.
