I carry one floating line for all types of fly fishing. To fish a feathered lure I may use a swivel, or lead shot on a long leader to get some depth, or use a weighted homemade lure. For lure fishing I use a level leader of 10 to 12 lb strength, ditto the monofilament for spinning. Do not be fooled into thinking that it is sporting to fish fine when lure fishing - it is only necessary to do so for success when imitating insects on the drift. Landing a Fish Forget about landing nets.
Large fish can be a problem.
If this is not feasible then get in the water and carefully take hold of the fish by the gills and heave it onto the bank. In some countries and places it may be necessary to buy a license to fish for trout and salmon. Enquire at the nearest angling shop or tourist information center. Often there is a countrywide license as well as specific licenses for tourist fisheries and National Parks, and special rates for foreigners e.g., Chile, Argentina and New Zealand . You will find out what methods are legal and where to go and not to go.
