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. AY FREE . .

GODERICH SIGNAL -STAR, THURSDAY, MAY 18, 1978—PAGE 15A 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.
