In the River
Tay salmon from different tributaries constitute separate
breeding populations. This structuring of the population
is very important as it helps to main differences between
salmon, for example the highly varied timing of runs
of fish returning to different tributaries throughout
the year.
Recent advances in genetic techniques mean it is
now possible to “fingerprint” fish from
individual tributaries. Once fingerprinted it is
possible to tell where fresh fish entering the river
are actually heading.
This is important as it aids the identification
of vulnerable populations and can help target conservation
measures on those populations which most need them.
