| Lisätietoa: | Report 15 (XV) Abstract Salmon of the sea-ages 1SW, 2SW, 3SW, 4SW were caught in all the municipalities in Finnmark and in Troms and Nordland counties in the research periods in 2008-2021. The proportions of 1SW fish in male salmon catches were higher in Russia in many sampling areas compared to their proportions in Norwegian catches. Differences in the sea-age distributions between municipalities in Northern Norway can be explained by the fishing method used during the fishing season and by the period of allowed fishing. Large 2SW, 3SW, 4SW salmon and previous spawners ascend into the coastal areas earliest in the summer and are covering more than 50% of the weekly catches towards the end of first week of July (week 27). The smallest salmon, 1SW fish, starts to appear in the coastal catches in week 24. The numbers of 1SW salmon increases steadily towards to the end of week 28, in the middle of July, when their proportion reach 50% of the weekly catches. After the middle of July, the proportion of 1SW salmon in the weekly catches is stabile towards the end of the fishing season... |
