When in a survival situation, you will likely want to keep your actions as stealthy as possible to avoid attracting any unwanted attention. However, looking for food in your attempts at survival can lead to exposing yourself much longer than you would like.
A great solution to this issue is to get some mechanical fisher’s yoyo reels and set them up after the sun goes down with some natural material fishhooks. Chances are good that you will wake up to a fish or two on your lines. What’s most beneficial about these yoyo fishing reels is that they won’t require a rod, which means a substantial amount of space would be saved for your bug-out bag in general.
Most important when setting overnight fishing up, though, is that you want a strong foundation so a fish could theoretically be attached to the line for 8 or more hours without running away with the line its attached to or even your entire setup if you are using a cross-river technique.
