Presentation to NSWA Fish Forum Edmonton 25 Sept 2014 David Thompson
“I afterwards travelled much with him, and have now only to speak of him with great respect, or, I ought to say, with admiration... No living person possesses a tithe of his information respecting the Hudson’s Bay countries... Never mind his Bunyan-like face and cropped hair; he has a very powerful mind, and a singular faculty of picture-making. He can create a wilderness and people it with warring savages, or climb the Rocky Mountains with you in a snow- storm, so clearly and palpably, that only shut your eyes and you hear the crack of the rifle, or feel the snow-flakes melt on your cheeks as he talks.”

Goldeye
“1977 was one of my best times as a fisheries biologist. I canoed right across Alberta on the Battle River, catching fish, talking to people, and getting to learn how a whole ecosystem worked.”
“Locals told me how the big runs of goldeye were almost gone and how you could only catch decent numbers below Forestburg.”
“It was really evident that things were going downhill, with big kills of pike in Driedmeat Lake, low oxygen levels in big chunks of the river, and listening to stories about the sad state of the river.”

Dave Christensen 1978, Lacombe Lake As in past days, drinking, swimming, fishing in untreated river water is still normal in NSR headwaters Battle River June 2009
When will this be unacceptable? Battle River 2009 Beaver River 2010 42% White Suckers had lesions
This is not normal! Elsewhere… Doherty et al. (2005). WQRJ Can. White suckers in St John River NB near pulp mills, hydroelectric, etc. “During this community survey, a significant number of white sucker (Catostomus commersoni) were captured with external lesions (4–12% occurrence in adults), identifying a potential area of concern in the river reach near the Beechwood hydroelectric facility, as lesions in the species are rarely reported” When will this be unacceptable? When will this be unacceptable? Headwaters protection? This is illegal

Alberta’s Fish Dilemma: 10 ha = maximum sustainable harvest of 3 (big) to 10 (small) walleye 10 ha = 20 – 40+ anglers How do we get 10 ha = 3 big walleye? 1) Estimate walleye numbers - Pop’n est and FWIN Buck Lake 2010 (2527 ha) 2) Objective: Stable or Trophy? - stakeholder decision Walleye > 43cm = 4.3/ha - trade-off between harvest and size of fish Objective =10/ha 3) Calculate Total Allowable Catch (TAC) - simple math Plan: recover, with some harvest - 5% (trophy or recovery-focus) - 10% (harvest -focus) TAC = 5% of pop’n = 0.2/ha (2 in10ha)
TAC walleye >43cm = 543 fish Angler Effort at Buck (2008) = 20,000 anglers
= must share each fish with 37 anglers Low Productivity meets Heavy Fishing Pressure

Alberta’s Fish Report Card = Fish Sustainability Index - each species and 30 watershed gets scored - scores reflect fish status and threats - trends in score = success or failure - full public transparency of data and results Fish Sustainability Index (FSI) - On the surface
Simple scores (1 to 5) Population Integrity Rigorous rule set (40 pages) (is the fish pop’n healthy?) 8 parameters Productive Potential (was it naturally weak or healthy?) 3 parameters Consistent Threat Mitigation Transparent (how much attention does it need?) 5 parameters Loss of Christina River Grayling
Martin Paetz (former Fisheries Director) - in 1967, he went in to film a CBC film. He stood in one spot and got 33 grayling, all over 12 inches in less than an hour. - in 1987 he went back to the same spot. Two people fishing hard for two days caught seven grayling, one over 12 inches.
Oil Sands Aquatic Monitoring Program (Christina River) From 1984 to 2001, 21 angling studies caught 0 grayling From 2001 to 2010, electrofishing studies (207 studies) caught a total of 2 fish Loss of Christina River Grayling Arctic Grayling FSI (early)
62 watersheds with grayling < 20% intact pop’ns
5 watersheds considered “good” (numerous small fish, fewer adults) Lower Little Smoky, Caribou Mtns. Christina At least 10 populations lost Several more suspected lost
Not a pretty picture…but important to show the big picture Down-scaled FSI: Simonette River
Grayling Anthropogenic Risk Scores
- Very useful for describing present level of risk in the context of fish during DFMP development Above 20% to 30% land disturbance (agri, forestry, roads), former grayling streams became anoxic during winter Alberta’s stream habitats and fishes showing effects of people and development Main Issues: 1) Eutrophication (green water) 2) Flow (less groundwater) 3) Access and overharvest
Solution for better fishing: fewer roads , more trees, less footprint
So how are we doing compared to our neighbours? Brown Trout don’t like Alberta’s cold
Extensive stocking, no sustainable fisheries
Raven is unusual Extensive stocking, -warm ground water, Few sustainable fisheries in a cold climate

John Nishi, Will Stelfox Bow River July 2004 Alberta’s basic fisheries issues
Lake fisheries (walleye and pike)
10 hectares of northern lake -sustainable harvest 10 walleye (small) or 3 walleye (big) -attracts effort of 20+ angler-days Must share 1 fish with many anglers Stream fisheries (trout & grayling)
Habitat shared with forestry, agriculture, petro -Many streams lost in non-protected areas -Increasing pressure on few remaining streams Must share fewer fish with more anglers
= trade-offs between stakeholders
Problem: too many ineffective regs and rules, failing to communicate and solve the real issues
Lesser Slave Lake 17 Feb 2013 Solutions
Improve and simplify regulations
Provide anglers and public with clear, transparent status of fisheries (FSI)
Give industry meaningful, useful information of effects on fish (FSI and dose-response curves)
Thank you! Alberta is a cold, northern place to be a fish

Alberta is a good ($) place to be a person Hi folks just passing on some good news on PLAR being consistently implemented in the West country by our local RCMP. We typically provide between 10 – 20 impact statements for OHV’s driving in creeks out of the Rocky Office each year. Many of these statements are used for more than one offence on the same waterbody or within the same drainage. Minimum fines are $500 and we have been getting much higher fines than that. In one case the crown kept the offender’s ATV and returned a second ATV after holding it for nearly a year. John Tchir

Both individuals plead guilty and received $650 fines.
>>> Wayne HOWSE 2014/05/29 1:18 AM >>> Hi John, on May 18th, 2014 Cst Cavanaugh and I charged 2 individuals for driving in Vetch Creek and both are appearing on July 9th, 2014. They were driving in and obviously washing ( pushing mud etc off). I believe you had provided a impact statement last year on this creek. Just wondering if you could provide us with another updated one.
Thanks
