    Assessing Temperature Tolerance of Bonneville Cutthroat Trout Based on Constant and Cycling Thermal Regimes

    Abstract.—We assessed the response of Bonneville cutthroat trout Oncorhynchus clarki utah to constant and cycling thermal regimes in the laboratory. The 7-d upper incipient lethal temperature (LT50) based on a constant thermal regime was 24.2°C[75F], and no fish survived temperatures greater than 25°C[77F]. All cutthroat trout survived a 7-d exposure to a diel cycle of 16–26°C, despite a 6-h daily exposure to temperatures (>24.2°C) that would be lethal under chronic exposure. However, declines in feeding and activity were observed during the 16–26°C cycle, indicating that long-term exposure to such a thermal regime would be detrimental. Mortality occurred when diel temperature cycles were escalated to18–28°C.

    Effect of Temperature on Growth and Survival of Bull Trout,

    with Application of an Improved Method for Determining

    Thermal Tolerance in Fishes

    JASON H. SELONG AND THOMAS E. MCMAHON

     

    Abstract.—Elevated temperature is considered an important factor in the decline of the threatened

    bull trout Salvelinus confluentus, but the thermal requirements of this species have not been defined.

    We used the acclimated chronic exposure (ACE) method to assess the upper thermal limits and

    growth optima of bull trout fed daily to satiation over test temperatures ranging from 88C to 288C

    during 60-d trials. Survival of age-0 bull trout was at least 98% at 8, 10, 12, 14, 16, and 188C,

    but 0% at 22, 24, 26, and 288C after 60 d. The predicted ultimate upper incipient lethal temperature

    for these trout was 20.98C.

     

    TROUT TEMPERATURE REQUIREMENTS (LITERATURE REVIEW)

    Stressful and Lethal Temperatures

    Based on available literature drawn largely from laboratory studies (Cherry et al. 1977,

    Raleigh et al. 1984, Currie et al. 1998, Coutant 1977) the upper incipient lethal

    temperature (UILT) for rainbow trout is within the range 25 to 30°C. Eaton et al. (1995)

    identified upper temperature criteria for rainbow trout as 24.0°C.

  2. Taco,

     

    Posed the question to a friend and he said what about all the South African Professionals showing up in Canada. Nearly all are white. But should they be called African Americans. But African Americans, as far as I can figure, all black.

     

    And you think you got troubles. Grandmother on Dad's side was a Laplander but born in Sweden. Married Danish. Grandmother & Grandfather on Mom's side were both US Citizens but Mom was born in Seven Persons Alberta [a place so small they considered renaming it to Eight Persons when Mom arrived. Mom carried dual citizenship till 60+ years old.

     

    That's it, I've had it!. When Global TV comes to visit about issues in Canada, I gonna be a Canadian - Canadian.

  3. If you were born in Canada, you're a Canadian.

     

    If you're a French-Canadian, yes your ancestors came from France, but I think in todays context you're a French (speaking) Canadian.

     

    N'est pas?

     

     

    But I'm still confused. Now there are French Canadians and English Canadians but only to describe those people in Canada. French Canadians are from Quebec or NB where as the English Canadians are from the rest of Canada. Now if you were born in France, emigrated to Quebec, do you become and French French Canadian. Similar rules might apply to English Canadians born in the UK.

    Boy does this multicultural society get confusing.

  4. Folks,

     

    Been thinking about the words used to describe people in Canada.

     

    1] We have Irish Canadians, Scottish Canadians, Chinese CDN's, Japanese CDN's but how come we don't have American CDN's. After all, there are >70,000 living in the Calgary area.

     

    2] My family has been in Canada for over 100 years and 5 generations. When do I become a Canadian Canadian? Certainly it would be foolish to link my grandkids with my grandfather. So am I a Canadian Canadian or a what-a-be?

  5. Hydropsyche,

     

    The wing case has a small strip of black Phentex yarn pulled over the herl.

    The bodies are of Flashabou. Numbers on the flies correspond to the numbers stamped on the packaging.

    The bodies are either glued with Loctite Super Glue or Sally Hansens Hard as Nails.

     

    catch ya'

  6. chronie63,

     

    The body is invisible sewing thread available @ most sewing shops. You'll have to load the invisible stuff to a empty spool as the invisible spool is about 1000 yards.

    The head is Arizona Sparkle Yarn - herl color - the gills are Stillwater Solution gill yarn - the rib is 0.003" copper wire - glue is Loctite Super Glue from CDN Tire.

     

    To load the spool, I use a 3/8 variable speed drill, a 1/4"*1.5" long bolt c/w nut. Slide the MT spool on the bolt and tighten nut. Chuck into drill. Put invisible thread spool on some type of post. I use a Robertson screwdriver mounted @ a slight angle in my 4" metal vise. Don't put too much on the MT spool. The thread tends to "spring".

  7. Note the absence of beads on most of the patterns shown. In my experience, they really are not required. The un-beaded hooks sink quite well and may take a couple of seconds longer to reach depth if you are using an indicator. Using a quite long leaders of +20' and a floating or neutral density line, an un-beaded pattern fishes a tad better as you can fish it slowly w/o hanging up on the bottom. And if I use a bead, it is typically a plastic or glass bead to slow it's descent.

  8. Guys,

     

    Page 19 of General Regulations under Additional Restrtictions says " Angling not permitted through ice [a] into beaver ponds or into flowing waters in Zone 1.

     

    Guess that settles the fishing through the ice issue.

     

    Guess the dates regulation was chosen to limit ice fishermen. Govt' must recognize an issue and therefore installed dates. The issues are fishing through ice.

     

    And Clive, I fear that some ice fisherman or other WILL FALL THROUGH a hole provided by aeration units. The Govt will get sued and back out of aeration quick. There goes a pile of possible lake opportunities.

     

    catch ya'

  9. Guys/Gals,

     

    Each of these lakes has a date when it's legal to fish. Problem with dates is Clive. The climate is getting warmer or colder depending on his issue of the day with the result that date ice disappears keeps changing.

     

    OK - been in Alberta for +60 years. Think I discovered ice about age 2. So most of us know what ice is. Just publish the regulations saying no fishing through the ice. Simple!! Dates don't matter.

  10. Taco,

     

    The jigs are spin rod equipment or you could dap them with a shiny new spey rod. The ones in your picture a a tad involved with a whole lot more materials than needed. Bulls can be caught on rabbit turds. They aren't terribly bright.

  11. Hey rick,

     

    Hate is a purty ugly word. Don't hate Walmart. We haven't got one. Rocky Town Council turned the leeches down. Walmart wanted $800,000 in tax relief to locate here. Hell, we don't subsidize local merchants and most of them were born here. Now why in the devil would we subsidize a business whose aim is to put local merchants outta business all the while sending the profits south. We want a second chance @ the dollar and that can only be obtained by merchants who shop locally.

     

    As far as prices - taint the law @ Walmart. You better do a little competitive shopping - a whole lot of business provide goods cheaper and of better quality. Yupe - been in the place - twice - know thy enemy.

     

    And whats a MTB?

  12. Guys/Gals,

     

    Here are some tips about hand care for tying.

     

    1] The best hand lotion I've ever found is Corn Huskers Lotion unfortunately only found in the USA. It's not popular and therefore suffers the indignity to being stuffed on the lower shelves of the drug stores. It's oil free and cheap. Google it for a list of suppliers

     

    2] The little "wickers" on hands grabs everything. The best cure I've used is a teaspoon spoon of salt poured in your palm with a table spoon of baby oil or cooking oil added to it. Liberally rub your hands together. Will remove most of the little skin breaks.

     

    3] For that junction between your finger and thumb where all the fly tying thread has to slip through when holding materials, use a finger nail buffer. Buff the area on your finger and thumb. It is available in four grits mounted on a foam block. See your local cosmetics counter. For those really cheap, a piece of 400 wet/dry sandpaper glued to a hockey stick end works as well. The buffers are about $4.00

     

    4] Bounce or anti-static cloths work well to get rid of the static that dry climates seem to suffer. Rub your hands in the cloth. Now you will able to keep up to marabou.

  13. Weedy 1,

     

    Ya' gotta get out more.

     

    From my experience of picking up @ Beaver Lake. I found my first identifiable piece of FF garbage last year. I usually fill 1>2 grocery sacks of bank garbage consisting of bait containers and beer bottle/cans/timie cups and the odd spin rod. You want to see a real pile of bank trash, go to Bullshead. Sorry to inform you, but FF types seem to be cleaner.

    Do recall a guy who owned land along Stauffer creek who told me he sure liked the new regulations of no bait. He hadn't kicked off anyone for garbage throwing or fire-lighting all summer. Used to fill 2 garbage bags each spring prior to the bait ban. Rarely get garbage there now.

    Did you ever wonder who drives the trout agenda in Alberta. FF types. Still waiting to see my first worm dunkers trout club doing anything. Whoops - there are no worm dunkers clubs unless you can call the AF&G their representative. Whoops yet again - don't see AF&G doing spit either.

    Wished that the worm dunkers would step up. Sure, some do - not a lot.
