Cold Weather Delays Vaccination

NORWAY - In January sales of vaccines to salmon were 20 million doses. This is a reduction of 34 per cent compared to January 2009. The main reason for this is due to the cold weather and water temperatures in south Norway delaying vaccination.

The vaccination against ISA now includes close to 10 million fish a year. This number will increase significantly if the authorities open for an extended use of ISA vaccines in 2010.

If this is the case, how extensive an ISA vaccination will be too early to say, but a conservative number might be at least 50 million doses.

Another vaccine segment is vaccination against pancreas disease. Pharmaq statistics show no major changes in the number of fish vaccinated against this disease and 12 month rolling figures varies between 95-105 million fish.

Nearly all sales of vaccines for farmed cod are water based vibrosis vaccines. More than 96 per cent of the 9.1 million doses sold in the last 12 months were water based vaccines. This vaccine segment has fallen approximately by 70 per cent over the last year.
