Environmentalists are concerned about a vulnerable colony of porbeagle sharks after a fisherman caught 60 in a day. The sharks, although rare are currently not a protected species. A catch of this size could be enough to wipe out a whole colony due to the fact it would be likely to contain most of the colonies breeding females. The decline of this species is likely to continue until they are listed as a protected species. If this doesn’t happen soon it may be too late.
