HomeMy WebLinkAboutThe Goderich Signal-Star, 1978-05-18, Page 37Fishing is a popular pastime in the Port Albert area. But Port Albert
residents often find fishermen are careless about their habit while
"fishing, and on occasion, have been known to destroy private property
during their visits. Fishermen do spend maoney at the general store in
Port Albert. And they do rent accommodations from time to time. Port
Albert foks, do wish that anglers would fish the river and respect private
property at the same time. (photo by Dave Sykes)
Port Albert fishway .....
• from page 13A
trout to get past the Port
Albert dam to spawn. He said
a hole in the dam was the only
route the fish could take to get
upstream and conditions had
to be ideal for the trout to get
through it. He said those
conditions were sometimes
never right in past spawning
seasons. He said water levels
and the flow rate had to be
just right for the fish to get
through the hole in the dam
and when those conditions
were met they would only last
a day or two at the most.
The fishway is basically a
water diversion skirting....th<e
five foot damthat spans the
river. The water flows
through a concrete spillway
and is dumped back into the
river below the dam reducing
the jump the fish must make
from five feet to one foot. Fish
heading upstream to spawn
instinctively follow the
current of the river and that
instinct causes them to swim
to the bottom end of the fish -
way. They jump over the
barricade, swim' up -the
concrete spillway and are
trapped in a wire cage about
five feet long and three feet
wide.
-Each hour Walroth and
ministry employee Lloyd
Tigert use a chain hoist to
raise the cage. The trout are
netted.out.of the cage and put
in bathtub like containers
awaiting processing. Tigert
scoops the fish out of the tubs
by hand, places them �n a
measuring table and Walroth
records the fishes' weight,
length, sex 'and spawning
condition and a tag is sewn on
its back. Tigert then puts the
fish in a foot wide tub that
carried the fish back to the
river above the dam.
Walroth said the size and
condition of the fish trapped
in the fishway indicates life is
good for a rainbow trout in
Lake Huron. Some of the fish
have large scars from
lamprey attacks but those
scars indicate the fish are
capable of surviving such
attacks more readily than
lake trout, a species
devastated by lamprey.
Walroth said the average
weight of trout passing
through the fishway has been
about five pounds and the
average length 25 inches. He
said the tagging operation
will permit ministry staff to
trace the movement of the
fish, expected life span,
growth trate, spawning
success and ability to survive
through the perils of water
pollution, lamprey attacks
and.an increasing number of
sport fishermen.
The tagging is not new to
trout in Lake Huron. Ministry
employees have been tagging
fish at the Saugeen River
fishway at, Southampton for
five years and some of these
fish have chosen the Port
Albert fishway as a spawning
route this year. Port Albert
fishway staff are hopeful they
can return the favor next
year when some of their fish
use the Saugeen fishway as a
spawning route.

Wheat gr.�wers seek
to end sprout losses
Pre -harvest sprouting, the
bane of winter wheat
growers, may soon yield to
the scientists' efforts. Prof.
N. F. Derera, director of
wheat breeding, University of
Sydney, and Prof. L. A Hunt,
department of crop science,
University of Guelph, hope to
make some joint headway
this summer in tackling the
problem.
Prof. Derera, who is
spending a period as a
visiting professor in crop
science at the University of
Guelph, has brought with him
seeds from his breeding
research at Narrabri in
Australia. Australia's nor-
thern wheat growing area has
extensive summer rainfall
and so sprouting has been a
problem with white wheats
there, just as,in Ontario.
Since 1973, Australian plant
breeders have discovered
that a number of hereditary
characteristics including
seed coat liquid dormancy,
may (depending on con-
ditions) protect against
sprouting damage.,
Laboratory back -crossing
methods have successfully
introduced these charac-
teristics into previously
susceptible •varieties and it is
expected that Australia will
eventually be planting white
wheat resistant to pre -
harvest sprouting.
"During the five months
which I spend at this
University, I hope to learn
more about sprouting
physiology, in addition to
initiating the control
program," says Prof.
Derera. He brought with him
from Australia all of the
techpology and much of the
germ plasma which will be
needed to set up breeding
programs here.
"Guelph is benefitting from
pro'IoIl/ Yrl:rs'.Errh and
technology developed in-
ternationally," says Prof.
Hunt, "but will be one of the
first areas to implement the
findings. The fundamental
work achieved to date, which
has sorted out the com-
ponents of sprouting, will be
brought to a focus to handle
this problem which Canadian
farmers have".
Jewell award is new
A new award at the
University of Guelph to en-
courage farm broadcasters
and journalists will also
honour one of Canada's best
known agricultural com-
municators. The Roy Jewell
Award of $500 will be offered
annually to a graduating
student who has shown a high
degree of interest and ex-
cellence in studies related to
. agricultural com m un ication
and extension.
The scholarship arises
from a fund established to
honor the retirement of Roy
Jewell from his position as
farm director of CFPL radio
and CFPL-TV in London.
Roy Jewell began his
journalistic career in 1948 as
director of farm services for
the London' Free Press and
