I think it's important to work on these issues of fixing fishing mortality according to knowledge about the stock and the conditions of the sea at present. These things worry us quite a lot, depending on the situation in the area that the stock utilizes for spawning or for feeding, and so on.
For instance, in the last five, six, or seven years, we have had a temperature increase in the Barents Sea, which is the important feeding ground for the cod stock. The ice cap has retreated quite substantially in the Barents Sea, and this has made it possible for the cod stock to utilize a much greater area of the Barents Sea for feeding, and so on, than it did only some five to 10 years ago. This meant that the cod stock grew more than we expected, which also makes it possible to fix a higher fishing mortality rate in our management regulations of the stock.
It's important to follow the development of the conditions for a stock and use the knowledge from historical periods for the stock to fix a good harvest control rule. It's not something done once and for all.
