Fishing with a bubble or float is an old technique. I’m sure most of us have used this method with live baits to catch a variety of fish. It also works well with flies and other floating lures to catch trout.
My handline of choice is Streamlines Tideland which weighs 2.4 oz. I cut the rubber handle off mine (saving an ounce). It now weighs 1.5 oz (43 grams). You can easily cast over 20 metres accurately. It is as good as most spinning rods, better where there are overhanging branches, as you can cast underarm. It is ideal for getting a trout dinner out of small wooded alpine streams. I could trim its weight some more by cutting off the corner with the angle grinder and smoothing the finish. I might get it down to a functional 1 oz (or 30 grams), yet still have a superlative casting hand line.
Below are typical rigs taken from Martin Joergensen’s and Will Rietveld’s articles below.
The technique is simplicity itself. Cast and slowly retrieve. The splash of the bubble hitting the water attracts the fish’s attention which is then directed at the fly tied to the invisible line. When it strikes you need only set the hook, reel it in, prepare it and eat it. More detailed tips in the articles below.
‘The Streamlines handline has landed trout in the Sierra Nevada mountains, bass in low land lakes, and up to six pound snook in Costa Rica. The Tidelands model is an inexpensive lifetime tool, ideal for backpackers, kayakers, or as a part of any complete survival kit. Casting handline has been used for decades in Costa Rica as the primary tool of ocean shore-line fishermen who must live on what they catch. Streamlines has evolved this tool, combining improved design with modern materials. It casts far and accurately, limited only by the skill of the fisherman. This go anywhere, fish anytime tool is patented and molded of plastic strengthened with 40% fiberglass reinforcing. It is overmolded with a rubber Santoprene handle.’ http://www.moontrail.com/accessrs/a-misc/handline.html US$ 17.90
You could even do it with my 4 gram fishing hand lines below:

For an ultralight hiker/fisherman I think Will Rietveld’s method of cooking trout takes some beating (particularly if you were using twigs in the Caldera Cone). However, I have also been experimenting with various dry ingredients to make up a tasty fish chowder. Continental French Onion Soup is probably already a standby with you (though it takes a five minute simmer). A packet contains about 8 teaspoons full which makes four cups, so you can make them individually. Added to the (filleted) fish, it makes a tasty broth. You can thicken it (as I have mentioned before) with some Continental Deb mashed potato. A little milk powder will add to the chowdery effect. Some ‘Surprise’ peas might also help. I know you don’t have to add pepper or curry powder to everything (so my wife, Della says) but these can add some zest to the overall effect. Enjoy.
