THE TWEED Commission’s news website carries an interesting genealogy table for its spring salmon runs.  This shows the origins of fish dating back to 1999 and reveals that most of the springers are five years old, having spent a year in gravel as eggs, two more years in the river and two at sea.  The data is a worthwhile addendum to the dismal figures for this year’s spring catch returns which has resulted in a plea from the ASFB for a 100% catch-and-release programme until June.
