Albert (fishwayduring the spawning run that began in mid-April. The fish pass through a
concrete spillway that bypasses the Port Alert dam on Nine Mile River and are tem-
porarily trapped in a wire cage that is lifted lom the water to net the fish out. The trap is
lifted once every hour and tliis'lift resulted in the tagging of 10 good size trout. (Photo by

The condition of each fish that passes through the Port
Albert fishway is noted and recorded in ministry of
natural resources files. The fish are tagged for iden-
tification and If caught in the future in another fishway
the progress of the fish between spawning seasons can be
monitored. This fish bears a Large scar indicating it
suffered from a lamprey attack recently. The rainbow
trout has been able to withstand lamprey more so than
lake trout which were devastated by -the parasite. (photo

Port Albert fishway makes
life easy for spawning trout
BY JEFF SEDDON
Anglers doubting the
presence of rainbow trout in
Nine Mile River at Port
Albert need only witness
ministry of natural resources
employees tagging trout at
the Port Albert fislwiway to
have those doubts removed.
Since April 17, when the
first rainbow was caught in
the fishway, over 425 trout
have ignored the tasty
morsels offered by fishermen
at the river mouth and moved
through the fishway on their
way up river to spawn. The
trout run, small in com-
parison to other rivers em-
ptying into Lake Huron, is the
first to:r be helped up stream
by the . recently constructed
fishway.
Bob Walroth, contract
biologist at the fishway, said
Thursday that the small
numbers of trout trying to get
up Nine Mile River to spawn
is not surprising. He said the
fish normally return 'to the
same river they were born in
and spawning in Nine Mile
has been unsuccessful in the
past. He said many of the
trout trapped in the fishway
are mature fish adding
support to the theory that the
Port Albert area has been
unproductive in the past.
Walroth said a combination
of the Port Albert dam,
bypassed now by the fishway,
and large numbers of spori
fishermen dipping their lines
in the confined area between
the dam and the river mouth,
are the two main reasons for
poor spawnings. He said very
few trout made it past the
dam because of its size ad-
ding that the movement of
fishermen through the water
below the dam combined with
the fish caught during the
spawning run reduced the
number of trout born recently
in Nine Mile River
significantly.
•That fact should change
with the installation of the
fishway according to
Walroth. He said the success
of the fishway will not be
known for another four or five
years .. but claims that the
number of trout returning to
Nine Mile River in five years
should increase tenfold. He
said he expected about 500
fish to be trapped in the fish -
way this year and about 5,000
in five years.
Roy Bellinger, con-
servation officer with the
ministry, pointed out that it
