Project Description:
Warm temperatures can limit the maximum performance of fish hearts, which results in an oxygen shortage that can impair migration. While this limitation has been well studied in more southern fish, little research has been conducted on culturally and economically important arctic fish such as Arctic Char. This lack of information is especially concerning as the Arctic is warming much faster than the other parts of the world. Based on these concerns our project has three goals: 1.Determine the ability of adult migratory Arctic Char to tolerate warm water 2.Use this information to help make predictions about how char migrations will be affected by climate change 3.Demonstrate that we are able to conduct this type of research in a remote Arctic field setting using the newly developed research infrastructure in the Cambridge Bay area. To achieve these goals we will capture adult Arctic Char by angling or gill netting, move them in cool water to a holding pen and then warm them in a tank while monitoring their maximum heart rate. In 2018 research will take place at the commercial fisheries sites at Lauchlan River (Byron Bay) and Jayko River. Fish will be anaesthetized (put to sleep) during these experiments so that they do not experience discomfort and maximum heart rate will be achieved through injections of two pharmaceutical drugs that are commonly used in humans, one that prevents the brain from slowing down the heart and another that acts like adrenaline to stimulate the heart. As the fish are warmed up their maximum heart rate increases to a point where it cannot increase any further and then it begins to fail. By looking at these points we can determine optimal (good), sub-optimal (harmful) and critical (lethal) temperatures for migratory Arctic Char. We can then compare these temperatures to those measured in streams and rivers in the area and to predicted temperatures to identify areas where the performance of Arctic Char migration may be impaired, information that would be useful for management.

Waste and Impacts
Environmental Impacts
Both Lauchlan and Jayko River already has some level of disturbance as they are the site of commercial fisheries camps and have permanent structures (e.g. Cabins). We do not anticipate any substantial environmental impacts based on the fact the area is already in active use, and given the small scale of the proposed project, no land vehicles used and only 2 people temporarily staying on the site. To further mitigate risk of environmental impacts we will keep stored fuel and waste away from shore (>100m).
Waste Management
Waste Type Quantity Generated Treatement Method Disposal Method
Hazardous waste 5000L The waste will filtered through activated carbon filters which will remove nearly all of the chemical and then spread on a porous substrate which will allow and remaining chemical to degrades in sunlight. This anaesthetic is commonly disposed of through municiple waste water systems that do not utilize carbon filtration so our disposal method is more precatuationary than most. Fish Anaesthetic will be disposed of daily by spreading on pourus substrate (sand or gravel)
Greywater 20L/ Day Municipal water treatment system Stored and disposed of daily in municipal waste water system
Sewage (human waste) 4L/Day none Waste will be burried at least 100m from any freshwater sources
