| Lisätietoa: | Report 19 (XIX) Abstract Official salmon catch statistics have been available since 1972 in Norway and Finland. In the year 1979 the bilateral Tana fishery agreement required both countries to initiate common annual researches, including also the work on salmon catch and fishery statistics. In the River Tana watershed, both in Tana mainstream and in all the tributaries, there has been four net fishing methods allowed to use in salmon fishing since 1873. The methods have been drift net, weir, gillnet and seine fishing. These methods have been allowed until present day, except seine fishing that became prohibited in the year 2017. Rod fishing has been used as long as it has been technically possible. The periods 1974-1976, 1983-1985, 1991-1992, 2000-2001 had peaks in the catch statistics, and they were simultaneous in both countries. After the last peak in the total catches, it was expected to see the next peak in the years 2006-2008 but it did not realize. Instead of the expected increase in catches, there was an all the time decline in both countries... |
