Yes, by survival I mean in the bush - not by a mall like Park Royal where you can make weirs from rocks and shopping carts and pick up salmon with nets in the pools thus created and assuming you are not a chemistry major who can make explosives in the forest to bomb fish like with dynamite; and don't know how to weave a net out of pine needles... Besides a spear (which would only be useful when salmon are running and/or in shallow water - because of water refraction) and besides an indian fish trap made of sticks stuck in the mud by water's edge, what else can be improvised in a forest in winter?
If fishing with 'rod', assuming you had a limited amount of space in your backpack, besides some basic tools and a survival knife what minimum fishing gear would maximize your chances? Since there is not going to be a reel or a tackle box at hand, realistically one could only have a small length of line, some hooks and a few small lures. But besides winter steelhead what species would you be targeting? What minimum length of line must your have for this type of improvised fishing is even to be attempted with a simple rod (you chopped down)? What strength line? What size hooks? Since bugs aren't easy to find in winter, what simple lures can be improvised?
CohoMan: do you know what plants in our forests could be used to produce this 'stunting' effect?
Driller: you mean with an improvised rod and float, right?
