The non-returning of fish tags recovered by Norwegian fishermen
Abstract
In addition to 5 N.Kr. reward for each returned cod, coalfish, haddock,
halibut and catfish tag, Fiskeridirektoratets Havforskningsinstitutt
introduced in 1959 an annual drawing of 1000, 500 and 250 N.Kr. for
tags, Norwegian and foreign, returned by Norwegian fishermen. The
extra reward system was in use during 1959-1961.
After the extra rewards were introduced, the reporting rate of tags
returned the same year as recovered and one or more years afterwards
has increased. The non-returning rate of tags recovered by Norwegian
fishermen in 1947-1957 was estimated to be at least 4-6 percent and
the indication from the calculations is that the non-returning rate is
decreasing with the continuous advertising and with people in the fishing
ports to receive the recovered tags.
