Scenario
You hook a loon while fishing
Action
Reel the loon in slowly: you do not want to set the hook deeper or have the line break
Use a fish landing net, towel, jacket, or blanket, to bring the loon out of the water
While de-hooking, it is most important to keep the loon from flapping around
Wrap it with a towel or use gloved hands
Hold the wings firmly against its back and brace the legs against its body
Eye protection is also recommended
Best practice to de-hook/untangle the loon is to have two people: one person holds onto the loon and the other removes the hook and fishing line
Additionally
DO NOT
Cut your fishing line: the loon will suffer a slow death from drowning or starvation
If your line breaks while reeling in the loon get help from anyone available to recapture the loon
DO NOT
Lift the loon out of the water by the fishing line: it will only set the hook in deeper and increase the risk of the line breaking
