Environmental group decries lack of action to save porbeagle sharks

HALIFAX - A Halifax-based ecology group says international regulators aren't doing enough to protect a type of shark known to frequent waters off Canada's east coast.

The Ecology Action Centre says that for the fifth year in a row, the International Commission for the Conservation of Atlantic Tunas has decided against new conservation measures for the porbeagle shark.

There is no directed fishery for this type of shark.

However, there are no rules against keeping the fish if fisherman capture them when fishing for other species.

Spokeswoman Heather Grant says bycatch is one of the largest threats to the species.

Grant says scientists consider porbeagles one of the most vulnerable sharks, which have been assessed as endangered by the Committee on the Status of Endangered Wildlife in Canada.
