Salmon spawn above Stronuich Dam in
the upper reaches of the River Lyon but there are concerns
at how well smolts from that area survive. Research
partly sponsored by the Tay Foundation has shown the
water is unnaturally cold in spring because it is released
from a dam, this affects the growth of fish and may
also delay their migration. Salmon parr will be tagged
by Tay Board staff with uniquely identifiable tags
prior to their migration as smolts. By emitting a radio
signal when passing a detector these tags allow the
migration out and return as adults to be recorded,
and their survival assessed.
By understanding these migration patterns it is
hoped that the dam can be managed to optimise their
survival.
