I have a telescopic Shimano similar to one in the link you posted. Although I don't consider it a survival rod, it is small and light enough to put into the pack for times we go hiking and there is good fishing nearby....which is very common in my AO. These rods are good for larger trout sized fish and thats about it.

Around here, any time after July, salmon by the millions start their journey up almost all the rivers, streams and creeks. Many times they are so abundant that in a true survival situation, using a rod and reel is slow as compared to other methods of catching them. This especially true in shallower water where the salmon more or less slowly scrape/swim/scrape their way up and through the gravel and rock beds. When the fish are in low water stream/creek areas like this, a strategic hit with a long hefty stick or a well placed throw of a 6-8 inch sized rock can yield a good dinner or few.
