Record-high juvenile numbers in the Reisa River

The initiatives and regulations to bring up the salmon population has given results in the form of record high juvenile numbers.

Very positive development in juvenile density

Norwegian Institute for nature Research by scientist Martin Svenning has delivered us fresh results from last year's juvenile counting in the Reisa River. In the period 1990-2003 we counted between 2 and 6 juveniles per 100 m2 on our 12 selected stations where we register juvenile density, and in this period it was not caught juvenile salmon on 25% of the stations. Since 2003 we have seen a marked increase in juvenile production. In 2008 there were 28 juveniles on average per 100 m2, and in 2010 were the result as much as 45 juveniles per 100 m2. At one of the stations there were 100 juveniles per 100 m2 in 2010. From being an river at the beginning of the 2000s with almost no salmon juveniles, the Reisa River is now a river that produces new and vigorous generations of Reisa Salmon.

The results shows that initiatives and regulations has given results

The results from the development of juvenile density shows that the initiatives and regulations have had a positive effect. Release of female salmon has led to a higher proportion of female salmon. This provides a greater amount of spawning fish and therefore greater production of juveniles. In addition, the regulations implemented in reduced sea catch has contributed to more salmon going up river to spawn.
