European carp appear to be the dominant fish in Canberra’s Lake Burley Griffin. It is estimated that carp make up 85 per cent of the fish biomass in the lake they share with trout and native species.
An ongoing review of the fish of the area suggests that carp were inadvertently introduced in amongst other fingerlings when the lake was initially stocked with trout species in the mid-1970s but they quickly made the lake home, lowering the water quality and making it more difficult for other fish to thrive.
More recently, the proposed release of a carp herpes virus is being hailed as the thing that is going to tip the balance in favour of native fish, however many questions have been raised around if and how it will work and what will happen to all the dead carp.
Experts have put together information and videos in a series of FAQs to help answer some of these questions. Go to http://www.pestsmart.org.au/carp-herpes-faq/.
A Marine Safety Alert has been internationally released by U.S. Coast Guard cancelling the approval certificate for NAMMO LIAB AB Orange Hand Smoke Distress Signal.
This is because the chemical makeup of the signal was changed in October 2013 without Coast Guard approval and the signal that was manufactured is at risk of spontaneous combustion when dropped.
These smoke signals may be labelled and marketed as 'Polar MK 4' by NAMMO LIAB AB or as 'IKAROS' by Hansson Pyrotech.
