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.

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.
If you have recently purchased this Hand Smoke Distress Signal, contact the retailer where you purchased the unit from, for a replacement alternative.
