NORWAY - For the first time, cod from the Norwegian Cod Breeding Programme are being slaughtered. It is now possible to compare properties of the different families, such as fillet weight and liver size.

The cod is produced at the Norwegian Cod Breeding Centre in Tromsø.

It is the first year class in the breeding programme, brought into the world in 2003, which has been slaughtered.

From each of the well over 30 family groups that are now being studied, 10 to 12 individuals have been selected.

Detailed information

For each individual fish, its total weight, cleaned weight and length are being registered. In addition, the roe, liver and several other organs are being studied.

A number of measurements are being taken, as well as samples of blood and muscles. Each fish is filleted and weighed to see whether there are differences in fillet yield.

"We are now getting detailed information about genetic differences amongst the families. This is information we use when selecting fish for further breeding", says Atle Mortensen, who leads the Norwegian Cod Breeding Programme.

The fillets from the breeding cod are being kept in cold storage at Fiskeriforskning such that the quality development can be followed during storage.
