| Summary: | No abstracts are to be cited without prior reference to the author.An International tagging program on both adult and young mackerel was implemented in 1997 (and partly in 1998) from Portugal to the Shetland isles within the frame of European Study Project 96-035 with the objectives of clarifying the migration pattern of adult mackerel from the southern and western areas and determining the recruitment spatial pattern of juveniles from two nursery areas, different from the current Mackerel box i.e. from the Northwest of Ireland and West of the Iberian Peninsula. Both external and internal tags were used in all the surveys in different proportions. A total of 161,115 mackerel were tagged along the European Atlantic coasts, 119,913 of them in 1997 and 41,202 extras in 1998. We report here for the recaptures obtained up to march 2001: Adult recoveries show that almost all adult mackerel (regardless of the discrete areas of tagging, southern or western areas) follow the same northward migration in late spring ... |
